One of the odd bits of knowledge that stuck with me from a college English class a thousand
years ago was this: “rival,” according to my learned professor, originally meant “friend.” To be
precise, it derived from a Latin expression that roughly translates to “one who uses the same stream.”
I guess it makes sense that you wouldn’t share a stream with an enemy. How that changed to the
meaning we all know now is anybody’s guess.
But that arcane factlet came to mind after seeing the recent deals and cooperations that have been
breaking out involving companies that you’d normally assume are, at least to some extent, fierce
competitors.
The most recent case in point is Cummins’ MOU with Daimler Truck involving medium-duty
truck engines. If it goes as anticipated, it will end with a Cummins engine plant inside a Daimler
facility in Germany. A “wow!” is in order.
Cummins will also be making engines for Hino and Isuzu (shameless plug – you can read about it
all in Global Engine News on the other side of this issue).
Now you might not consider Daimler, Hino and Isuzu to be competitors with Cummins. But they
all do make engines, as Cummins does, and history suggests that if you make engines, you’d rather
use your own than buy them from somebody else.
Of course, Cummins has made a living by supplying engines to customers who also make engines,
but it’s not just Cummins. Deere and Deutz are cooperating on engines (see February Diesel
Progress) and while some will go into Deere’s machines, it’s also quite possible that Deere, which has
a thriving engine business of its own, will sell some as loose engines. Where it is likely to butt heads
with – wait for it – Deutz.
And it’s not just engines. Daimler and Volvo are hip-deep in a cooperation involving fuel cells,
with the idea that they’ll work together to develop them for heavy-duty truck applications… at
which point they’ll go back to trying to knock each other’s brains out in the truck market. Hyundai
and Toyota are doing the same with fuel cells for cars.
At one time, it would have beggared the imagination to see such competitor cooperation. It just
wasn’t done. But technology is a whole lot more expensive these days and it’s clear that sometimes the
balance sheet wins out over brand loyalty.
They’re probably not ready to gather round a campfire singing Kumbaya, but companies seem a
lot more open to accepting help from anybody these days. Even from rivals.
Maybe we really all can get along.

A look at new power generation sets,
systems and controls
TAYLOR POWER’S UNVEILS
STREAMLINE SERIES GEN-SETS
Taylor Power Systems, the Clinton,
Miss., manufacturer of generator sets
used in standby and prime power
applications, has launched a new series
of generator sets the company said are
designed to “reach those customers who
are seeking a more efficient and refined
generator option.”
The new Streamline series gen-sets
are available in ratings of 40 to 150 kW
operating on natural gas or LP. Diesel
units rated from 30 to 200 kW will
follow in the coming months.
“The word streamline is synonymous
with sleek, efficient, and often simplified
design,” said Thomas Culpepper,
manager of Product Design and
Development for Taylor Power Systems.
“The Streamline Series embodies efficient
design and elegant simplicity. We
eliminated extra processes and materials
to provide consumers with a generator
that delivers quality, efficiency, and
simplified integration.”
The Streamline gen-sets are all
powered by gaseous-fueled engines from
PSI, in displacements of 4.3 L (40 kW),
5.7 L (60, 80 and 100 kW) and 8.8 L
(150 kW). The engines drive Stamford
three-phase (with dedicated single-phase
available) 12-lead reconnectable PMG
alternators, with engine and generator
functions controlled and monitored
through DynaGen TG410 Tough Series
digital controllers.
The units also incorporate a high
ambient radiator, engine jacket water
heater, two-stage radial air filter, molded
case LSI electronic circuit breaker and
COGEN SYSTEMS FOR SCHOOLS
Tecogen has sold a pair of its InVerde e+ cogeneration systems for use at a
school district in upstate New York. One of the systems will be installed in
the district’s middle school and the other in the elementary school. Both units
will provide electricity and heat to the facility at a discount to their existing
utilities. The cogeneration installation is part of a larger energy services
package to the district provided by a large Energy Services Company (ESCO).
“Schools continue to be a good market for our InVerde cogeneration
systems,” noted Jeff Glick, Tecogen’s vice president of East Coast Sales. “The
systems not only save the school districts energy costs but also are equipped
to provide backup power during a grid outage.
“The recent grid outages in Texas, closely following those in California, have
heightened public awareness of the increased risk from extreme weather
events and their often-devastating impact on communities. Cogeneration
systems like the Tecogen InVerde provide energy resiliency to facilities in
the form of both hot water and electricity that can be provided for indefinite
periods after the grid fails.”
The InVerde+ units are driven by Origin V8 natural gas engines that
drive Tecogen water-cooled permanent magnet generators that deliver 125
kW of electricity and 780,000 btu/hr of thermal energy that can be used
for heating. The units also include an inverter and the company’s TecoNet
microprocessor-based controls system.
Tecogen said it has installed and maintained more than 300 cogeneration
and chiller systems in the upstate New York area, primarily in school
systems. This project will be serviced from Tecogen’s Western New York
service center in Rochester, N.Y.

The gen-sets are packages within a
level 1 sound attenuated enclosure that
can be specified with polyester fiber
fire resistant foam. The powder coated
enclosure also includes lift-off doors
for easier servicing. Easily accessible
tie points enable securing to a slab and
provisions are made to supply customer
connections for remote start, remote
annunciator, generator running and
common alarms. ■

MECC ALTE TO
DISTRIBUTE
SICES
CONTROLS
Alternator manufacturer Mecc Alte will now
globally distribute Sices control products and
accessories.
“When an alternator is served to an OEM, it
is common that a gen-set controller is required
as well,” said Laura Curioni, chief executive
officer at Sices. “We hope this will make it
easier for customers to specify reliable control
products that work in synergy with market
leading alternator solutions.”
The Sices range will include generator
set, parallel and automatic transfer switch
products, along with hybrid controllers. The
products are used in several sectors worldwide
including mission critical data centers,
transport networks, telecommunications,
distribution and healthcare facilities.
PSI MILESTONE WITH
ENCHANTED ROCK
Power Solutions International, Inc. (PSI)
announced it recently shipped its 1000th

Rock, a Houston, Texas-based provider of
utility-grade backup power to commercial
and industrial customers. PSI and
Enchanted Rock entered into a multiyear
supply agreement in 2017.
Enchanted Rock uses PSI’s power
generation units, rated 400 kWe for
limited time running (LTR) and 448
kWe for emergency standby applications,

known best for agricultural
tractors – was founded in
Italy in 1926 and since 2015
has been part of the Arbos

plant. The company said
it has a clear strategy to
restart the Goldoni tractors
production as soon as
possible, focusing on making
specialized tractors, compact
transport vehicles and motor
cultivators, using Goldoni’s
tradition with Keestrack’s
innovation.
“After decades of organic
growth, we’re glad to
continue our growth by
expanding our business into
the agricultural segment”
said Kees Hoogendoorn,
president of the Keestrack
group. “After analyzing
many opportunities, we felt
personally drawn to Goldoni
for its rich traditional family
values which are very close
to ours. Our goal is to keep
this historic brand alive
supporting the local economy
and employment rates.”
Peter Hoogendoorn, vice
president of Operations of
the Keestrack Group, which
already operates its own
Italian factory for crushers in
Ponzano Veneto, added: “We
see a lot of synergy between
the current businesses, such
as: production systems,
suppliers and dealer network,
which will leverage the
Goldoni business to bring
success to the company.”
According to the CEO
of Keestrack Italy, Roberto
Lopes, the new owner wants

A monthly column devoted to the on-highway
truck market. By Steve Sturgess
The Work Truck show
that is historically in
March at the Indianapolis
Convention Center has
become a favorite of mine, not
so much as the launch site of
new heavy trucks but for the
usually hot news from Ford,
Ram Trucks and Cummins.
Mack usually has something
to make the visit to the show
worthwhile, too.
And Mack had a number
of announcements, but at this
year’s Work Truck Week ’21
it was a virtual launch like the
rest of the meeting. Not my
favorite way to experience new
introductions as I have griped
before.
That being said, Mack’s
announcements were fairly
significant on the whole.
Mack said its recently
announced medium MD
Series models are exceeding
customer and dealer
expectations for productivity
and performance, resulting
in strong order activity and
driving increased interest in
the medium-duty vehicles.
“Mack is proud that
customers and dealers
are excited about our
new Mack MD
Series,” said Jonathan
Randall, Mack Trucks
senior vice president of
North American sales and
commercial operations. “With
the addition of the MD6 and
MD7 vehicles, Mack now
offers a complete lineup of
Class 6 to Class 8 vehicles to
meet customer requirements.”
The Mack MD Series
includes the Class 6 MD6
with a GVWR of 25,995 lb.
and the Class 7 MD7, with
a GVWR of 33,000 lb. Both
models are exempt from the
12% Federal Excise Tax.
Available in 4x2
configurations, the Mack
MD6 and MD7 are targeted
at dry van/refrigerated, tank
truck, dump, stake and flatbed
applications. They offer a clear
back of cab and top of frame
rail to make it easier for body
builder adaptations.
NO CDL NEEDED
A Commercial Driver’s
License (CDL) is not required
to operate the MD6 model
as long as the payload is
non-hazardous. The MD6
and MD7 use Cummins
B6.7 engines, Allison
six-speed transmissions
and Meritor front and
rear axles. Additionally,
the MD Series models
feature a sharp wheel cut
for increased maneuverability
in tough-to-navigate job sites,
as well as a claimed industry-
best 103 in. bumper-to-back-
of-cab (BBC) measurement.
Mack’s other two
announcements were in the
CDL category. The Mack
mRide spring leaf over rubber
block suspension, ideal for
vocational customers needing
improved stability and
greater traction on jobsites,
now offers additional weight
savings for increased payload
when paired with proprietary
Mack axles.
Available at 40,000 and
46,000 lb. suspension ratings
and with standard track
axles, customers can save
140 lb. with drum brakes
and 146 lb. with air disc
brakes as a result of casting

The mRide’s parabolic springs
are thickest at the center to
ensure the clamp load area
offers the greatest strength and
are tapered to improve driver

Mack also said its highly anticipated active steering system, Mack
Command Steer, that is aimed to reduce driver fatigue, is now in
production in Mack Granite axle-back models.
Produced at Mack’s Lehigh Valley Operations facility in Macungie,
Pa., where all Mack Class 8 models for North America and export are
assembled, Mack Granite models with Command Steer help reduce
the physical demands of working on a jobsite, said Mack.
The system combines an electric motor with the Mack Granite’s
existing hydraulic steering. Multiple sensors throughout the truck
monitor the terrain, driver inputs and environmental elements more
than 2000 times per second. Based on the collected data, Command
Steer provides variable steering effort through its electric motor,
applying additional torque as needed to make it easier to keep the
truck on the desired trajectory.
Along with a significant reduction in driver steering efforts at
slow speeds, Command Steer suppresses uneven terrain, such as
potholes, dips and ruts. The system reacts to those irregularities
by countering the steer force, smoothing the steering feedback and
reducing steering wheel kick-back.
Mack Command Steer also has a return-to-zero capability that
automatically returns the steering wheel to the center position in
forward and reverse, helping to simplify tight maneuvers.

A monthly column devoted to the off-highway equipment markets.
By Peter T. Yengst
It seems like a daily
occurrence – every
direction you turn, you
see a growing number of
irregularities, inequalities and
gaps forming all around us.
While the writing may be
splattered all over the walls
and right before our eyes,
these changes often occur at a
very slow pace and over a long
period of time. They can be
impossible to see unless you
look back and spot the trend
as it emerges.
This is true in many areas
of life in general as well as
some much closer to home,
specifically, the growing gap
between skid-steer loader and
compact track loader (CTL)
sales. There is a divergence
that has been growing
between these siblings over
the past two decades that
really accelerated during the
pandemic.
Let’s take a brief trip back
to the early 2000s, where our
story of these two compact
dynamos really takes shape.
We’ve followed skid-steer
loaders as far back as the late
1980s, but for the sake of this
discussion, let’s focus
primarily on when
the CTL entered
the scene around the year
2000. The skid-steer was well-
known and had surged from
sales of less than 30,000 units
in the late ‘80s to roughly
73,000 units in 2000. A very
successful story indeed for all
OEMs participating, which
included familiar names
like Case, New Holland,
Gehl, Deere and the market-
dominating Bobcat, which
accounted for half of annual
sales.
CTL’S COOL TRICK
When we started covering
CTLs in 2000, sales were a
mere 3300 units, less than
1/20th of the skid-steer loader
market. Yet it didn’t take
long for this new variant
to become a hit as it had
a cool trick the skid-
steer couldn’t match – it
didn’t skid. The CTL
floated, sometimes gracefully,
over certain surfaces the skid-
steer dreaded. CTLs enjoyed
getting dirty and especially
flourished when it came to
slick areas and muddy job
sites.
The CTL was also more
forgiving on loose ground
and turf, leaving a smaller
footprint than its wheeled
sibling. Those attributes
gained much attention in
short order and sales exploded
more than 650% between
2000 and 2006. That success
didn’t come at any great
detriment to skid-steers, as
demand ranged between
50,000 to 60,000 annual
unit sales over that same
timeframe. The two brothers
each had their purpose and
loyal following of contractors
and landscapers.
Enter the housing crisis
and subsequent great
financial collapse. Both
markets took a staggering hit
along with pretty much all
other earthmoving machine
segments. As the markets
began emerging from the
rubble, both skid-steers and
CTLs climbed their way
back. Yet in 2015 it became
apparent that the recovery was
becoming K-shaped and CTLs
took the lead for the first
time. Sales of CTLs exceeded
40,000 units compared to
37,000 skid-steers sold that
year. From that point, CTLs
have never looked back.
CTL GAP GROWS
The Coronavirus added to
the growing sales gap, as
2020 sales actually ended up
positive for CTLs with a gain
of roughly 12% year over
year, versus a 7% decline for
skid-steers.
As of today, CTLs
command nearly three times
the sales volume of the skid-
steer market. Together, both
had a combined sales total of
over 100,000 units in 2020,
a silver lining considering
the bloodbath the rest of the
markets endured.
Over the years, Bobcat has
reigned supreme in both the
skid-steer and compact track
loader markets, so the shift
has been a win-win situation
for the top dog (or cat). Other
major CTL suppliers include
Caterpillar, Kubota, Deere,
Takeuchi, Manitou and ASV.
We expect skid-steers to
maintain a firm position with
tens of thousands of annual
unit sales, but the machine
that spawned the CTL 20
years ago will never see the
No. 1 spot again.
Similar evolutions have
taken place in automobiles,
and even more recently, with
the advent of electric vehicles
after more than a century of
internal combustion power,
where it also could take some
time to see the true divergence
take place. ■

This graph of raw index data is generated by the total dollar volume reported to NFPA by CSS participants
and compared to the average monthly dollar volume in 2018. For example, the January 2021 total dollar
volume for pneumatic shipments are 96.1% of the average monthly dollar volume in 2018.
Each point on this graph represents the most recent 12 months of orders compared to the previous 12
months of orders. Each point can be read as a percentage. For example, 75.2 (the December 2020 level
of the industrial hydraulic series) indicates that industrial hydraulic orders received from January 2020 to
December 2020 were 75.2% of the orders received from January 2019 to December 2019.
This graph of 12-month moving averages shows that in January 2021, both hydraulic shipments and

With much of the world still
firmly in the grasp of the
COVID-19 pandemic, it might seem a
strange time for any business to commit
to a major brick-and-mortar expansion.
Yet Kohler Power Systems, part of the
Kohler Power Group, is doing just that,
as the company has begun work on a
155,000 sq. ft. expansion to its existing
North American manufacturing facility
in Mosel, Wis.
And though the timing might appear
odd, from the company’s perspective, it’s
just another example of how Kohler has
always done things.
“In our 100 years in the power
business, Kohler has always taken the
long-term view,” said Brian Melka, group
president, Power at Kohler Co. “We have
to manage through the business cycles,
but as a family-owned, privately-held
company, we’ve always taken a longer-
term approach and don’t necessarily look
at what’s been happening this year or
last year, or what might happen in just
another year or two.
“The world needs power. That hasn’t
changed and if anything, it’s been

and peoples’ understanding of power and >

where and how they need it. The reality
is we made the decision to start forward
on this expansion last May, right at what
could be considered the worst time in the
pandemic.
“But that’s because we don’t make
decisions based on short-term thinking;
we make decisions based on the future,
not about what’s happening in a single
point in time.”
DEMAND GROWING

expected to be complete in 2023. It is
intended to help Kohler ramp up to meet
the growing demand the company has
seen with its higher capacity generators,
particularly in the data center segment.
“I saw a stat the other day that 90% of
the world’s data has been created in the
last two years,” Melka said. “Whether
that’s completely accurate or not, the
practical reality is that there has been
a massive amount of data created and
there will be a massive amount more
created in the future. For that kind of
expansion, you must have reliable power.
We create reliable power solutions
for mission critical applications like
data centers, hospitals, schools, and
telecommunications sites. It’s our fastest
growing area.
“The other thing that has been fueling
our growth is the instability of the grid.
And that is not just a U.S. thing, it is a
global issue. The infrastructure costs of
adding grid stability are astronomical and
so again, that need for reliable backup
power continues to persist, and we expect
it’s going to continue to accelerate in the
future.”
BIGGEST GEN-SETS
Kohler’s primary products for data center
and larger standby applications are its
largest KD Series generator sets. Last
year, Kohler unveiled the largest units
in that range, the KD3500 (3.5 MW)
and KD4000 (4 MW) Series generator
sets (see August 2020 Diesel Progress).
Those top end units have been primarily
assembled at the Kohler SDMO facility
in Brest, France, and in Asia. The Mosel
expansion will enable Kohler to assemble
and test the complete package for the
Americas.
“Because we’ve expanded our product
range to 4 MW, we can provide one of
the largest diesel backup generators in the
market,” Melka said. “Now, not only will
we have that product range, but we will
be able to build and test a fully enclosed
4 MW generator in our facility where a
customer can see it, fire it up, test it and
make sure it works before it is delivered
on site. Customers will not have to worry
that their mission-critical backup power
is being fired and tested for the first time
after it is delivered.
“We can do that today in our
European facility and we can do that in
our two facilities in Southeast Asia, but
we have been capacity constrained in
North America. We can test a 4 MW
unit here today, but not in the way we
want and our customers expect. It’s not
an elegant solution. This is going to give
us the capability to build these 2 to 4
MW power nodes on a dedicated basis.
“It is also really difficult to build large
generators in one location and then ship
them somewhere else in the world. I’m a
big believer in building products as close
to our customers as possible, whenever
that is feasible. That is true whether that’s
our small engine facilities or up to our
4 MW generators. It’s an advantage to
being as close to the customer as possible,
but also locating your supply chains as
close to your production facilities as
possible.”
INTEGRATED PACKAGE
The ability to assemble and test
complete generator sets also highlights
the company’s aims to be the only
manufacturer able to deliver a completely
integrated, high-power generator set from
one facility.
“When a customer asks, how is the
engine assembled to the alternator, we
can say, that’s right here,” Melka said.
“How are the enclosure and the controls

TAYLOR POWER’S UNVEILS
STREAMLINE SERIES GEN-SETS
Taylor Power Systems, the Clinton,
Miss., manufacturer of generator sets
used in standby and prime power
applications, has launched a new series
of generator sets the company said are
designed to “reach those customers who
are seeking a more efficient and refined
generator option.”
The new Streamline series gen-sets
are available in ratings of 40 to 150 kW
operating on natural gas or LP. Diesel
units rated from 30 to 200 kW will
follow in the coming months.
“The word streamline is synonymous
with sleek, efficient, and often simplified
design,” said Thomas Culpepper,
manager of Product Design and
Development for Taylor Power Systems.
“The Streamline Series embodies efficient
design and elegant simplicity. We
eliminated extra processes and materials
to provide consumers with a generator
that delivers quality, efficiency, and
simplified integration.”
The Streamline gen-sets are all
powered by gaseous-fueled engines from
PSI, in displacements of 4.3 L (40 kW),
5.7 L (60, 80 and 100 kW) and 8.8 L
(150 kW). The engines drive Stamford
three-phase (with dedicated single-phase
available) 12-lead reconnectable PMG
alternators, with engine and generator
functions controlled and monitored
through DynaGen TG410 Tough Series
digital controllers.
The units also incorporate a high
ambient radiator, engine jacket water
heater, two-stage radial air filter, molded
case LSI electronic circuit breaker and
COGEN SYSTEMS FOR SCHOOLS
Tecogen has sold a pair of its InVerde e+ cogeneration systems for use at a
school district in upstate New York. One of the systems will be installed in
the district’s middle school and the other in the elementary school. Both units
will provide electricity and heat to the facility at a discount to their existing
utilities. The cogeneration installation is part of a larger energy services
package to the district provided by a large Energy Services Company (ESCO).
“Schools continue to be a good market for our InVerde cogeneration
systems,” noted Jeff Glick, Tecogen’s vice president of East Coast Sales. “The
systems not only save the school districts energy costs but also are equipped
to provide backup power during a grid outage.
“The recent grid outages in Texas, closely following those in California, have
heightened public awareness of the increased risk from extreme weather
events and their often-devastating impact on communities. Cogeneration
systems like the Tecogen InVerde provide energy resiliency to facilities in
the form of both hot water and electricity that can be provided for indefinite
periods after the grid fails.”
The InVerde+ units are driven by Origin V8 natural gas engines that
drive Tecogen water-cooled permanent magnet generators that deliver 125
kW of electricity and 780,000 btu/hr of thermal energy that can be used
for heating. The units also include an inverter and the company’s TecoNet
microprocessor-based controls system.
Tecogen said it has installed and maintained more than 300 cogeneration
and chiller systems in the upstate New York area, primarily in school
systems. This project will be serviced from Tecogen’s Western New York
service center in Rochester, N.Y.

MTU STANDBY SYSTEM WITH AFTERTREATMENT
Rolls-Royce has launched a new
generator set system that directly couples
the engine and aftertreatment for a single
source solution designed to optimize
emissions performance. Based on the mtu
Series 4000 engine for power generation
applications, the gen-sets incorporate
a 12V configuration and come in four
ratings – 1350, 1500, 1600 and 1750
kWe – for 60 Hz standby applications.
“This latest version of the mtu
Series 4000 offers additional emissions
flexibility that our customers are looking
for,” said Mark Halbert, director of
Engineering for Power Generation at
MTU America Inc. “When coupled
with its SCR aftertreatment system
we can meet the strict emissions limits
that are mandated in non-attainment
areas. The engine can handle more back
pressure, so the size of the aftertreatment
system can be smaller, giving it a smaller
overall footprint, which our customers
appreciate.”
The aftertreatment system consists of a
diesel oxidation catalyst, diesel particulate
filter and selective catalytic reduction
system. It was jointly developed with
the Series 4000 G05 engine so that
the two work seamlessly together, with
all development taking place in-house
within the Power Systems business of
Rolls-Royce. The plug-and-play design
of the generator set and aftertreatment
system makes it attractive to customers as
it simplifies the design and specification
for the emergency power system within
the overall project, the company said.
The mtu Series 4000 G05 generator
set is certified to EPA Tier 2 without
aftertreatment. It is available with
optional certification to UL 2200 and
CSA. All mtu diesel generator sets
undergo rigorous Performance Assurance
Certification that tests the generator set
to ISO 8528-5 for transient response,
verifies product design, quality and
performance integrity and includes
prototype and factory testing. The mtu
Series 4000 G05 accepts rated load in one
step per NFPA 110 and has a permissible
average power output during 24 hours of
operation of up to 85%.
The mtu Series 4000 G05 is available
for order now, with start of delivery later
this year. The engines are manufactured
at Rolls-Royce’s mtu Aiken Plant in
South Carolina and the generator sets are
manufactured at its facility in Mankato,
Minn. ■

It has been said that every cloud has a
silver lining and even a near-fatal bite
from a black widow spider isn’t necessarily
all bad. At least that was my experience
about 15 years ago while recovering from
in the hospital after getting such a bite.
The medications used to combat the
spider venom had some mind-altering
side effects and it was during one of
those episodes that the inspiration for
what would become the successful Reed
A-Series Rockmaster concrete pumps
occurred. It was literally designed between
visits from doctors and nurses while I
recovered.
Reed has been producing equipment
to move concrete since 1957 with
products that include hydraulically
powered reciprocating piston units
using a hopper and drive cylinder and
air-propelled shotcrete units that mix
concrete in the nozzle immediately before
spraying it. These days, Reed equipment
is used for everything from sidewalks
and foundations to tunnels and walls on
multi-story buildings and even lining
kilns in steel mills.
ENTRY-LEVEL MACHINES
The pumps originally inspired by the
spider bite, the Reed A-Series, have been
powered by Perkins diesel engines since
their inception. Perkins was chosen
because its engines offered an optimum
balance between cost and performance
with good power curves, high power
density and plenty of torque.
These are entry-level machines and
buyers tend to be very price sensitive so
the Perkins value profile and excellent
reputation for reliability and longevity
all fit perfectly with the new design.
Reliability is invaluable in this day and
age, because nobody wants to get phone

calls, they just want customers to go out
there and use the machine and not have
to call with problems.
Today’s flagship of the A-Series is the
A40HP, which is powered by a Perkins
854F-E34T four-cylinder turbocharged
diesel rated 74 hp (55 kW) that meets
U.S. EPA Tier 4 emission requirements.
The engines are delivered by Reed’s
Perkins distributor, Perkins Pacific of
Ridgefield, Wash., complete with all
electrical connections, a cooling system
complete with fan, the correct mounts
and an aftertreatment package. The
distributor also provides spare parts
stocking and field support for the

A-Series pumps.
The Perkins engine drives a
Kawasaki KV3L-112 pressure
compensating, load sensing and torque
limiting hydraulic pump that powers
twin reciprocating hydraulic cylinders
that drive pistons in the triple chrome
plated concrete cylinders to pump and
pressurize concrete.
The A40HP is rated at 40 cubic yards
per hour at up to 1172 psi (80 bar). It
can move concrete up to 975 ft. (297 m)
horizontally or 400 ft. (122m) vertically.
This high pressure and volume capability
make the A40HP suitable for many
shotcrete applications which require a
combination of pressure and volume
typically handled by pump systems using
more costly technologies.
The Perkins engine drives either a
Rexroth or Parker gear-type pump that
powers the hydraulic outriggers for
stability and the S-Tube, also known as
an S-Valve, that directs concrete from
the reciprocating pistons of the concrete
cylinders into the discharge hose. The
pumping cylinder drive circuit includes
a flow-control valve that allows users
to adjust the output while keeping the
engine’s speed at a constant.
HOW TO RUN IT
In operation, the S-Tube is shifted
between the two concrete cylinders
fitted with the pumping pistons by a
cylinder that is driven via an accumulator
circuit. As one piston reaches the end
of its discharge stroke the S-Tube is
moved to the other cylinder which has
just completed its intake stroke. The
result is a virtually continuous flow of
concrete through the S-Tube and into the
discharge hose.
Switching of the S-Tube is controlled
electronically and the change from one
cylinder to the other takes less than 250
milliseconds. The mating surfaces on
the cylinder discharge and S-Tube are
made of hardened high-carbon steel, or
optionally carbide, to minimize wear.
The cylinder driving the S-Tube is
sufficiently powerful to shear rocks in
the concrete up to 0.75 in. (19 mm)
in diameter. The S-Tube has a reverse
function that can be used to clear
rock jams by sucking concrete out of
the discharge hose and back into the
pumping cylinder. It also features a
unique parabolic reduction designed to
keep concrete flowing evenly from both
pumping cylinders.
The hydraulic system is designed to
take a lot of abuse and work in very high
temperatures because of the cooling
system. If the machine is used properly
and regularly maintained, it can easily be
in service for 20 to 25 years.
The A40HP is a go-to for residential
work such as creating sidewalks and large
patios as well as swimming pools which
are often built using shotcrete. On larger
jobs its high-pressure capabilities allow
lightweight concrete to be placed up to
the sixth floor on a commercial building.
A-Series pumps are used for virtually
everything under the sun including lining
steel mill kilns with a special refractory
material that contains both glass and steel.
It’s heavy and hard to pump, but the
A40HP can handle it for distances up to
60 or 65 ft. and the Perkins engine just
purrs while doing it.
Not bad performance for a machine
designed during a near-death experience.
Not bad at all. ■

Sullair has launched its Mid-Range
Series of Tier 4 final portable
lubricated rotary screw air compressors,
which the company said were the first of
its portable air compressors to incorporate
electronic spiral valve technology.
“Electronic spiral valve technology
is a gamechanger in our portable air
compressors,” said Jerel Cole, senior
product manager at Sullair in Michigan
City, Ind. “Sullair electronic spiral valve
technology helps maximize fuel
efficiency and extend runtimes by
matching air supply to demand. It
allows an operator to quickly and
easily input the exact pressure they
want, anywhere between 100 or 200
psi, and the machine calibrates to
give maximum flow at that pressure.
It gives users all the air they want, at
the pressure they need.”
The company said the series is designed
for flexibility and efficiency, with the
800HH/900H model delivering 800
to 900 cfm at 150 to 200 psi, and the
920H/1100 model delivering 920 to
1100 cfm at 100 to 150 psi.
The units can be ordered with a
Caterpillar 7.1 L or a Perkins 1206J diesel
engine rated 302 hp. The 7.1 L diesel
engine replaces the previous generation’s
9 L powerplant.
New Sullair machines feature electronic
spiral valve technology.
FLEXIBLE MACHINE
The company said the series covers
the jobs of up to nine compressors.
Applications include pipeline work,
construction, abrasive blasting, fiber
optics installation, shipyards and more.
“Flexibility is at the center of how and
why we developed the new Mid-Range
Series,” said Cole. “For rental companies,
this means one compressor covers a wide
range of applications – giving rental
companies maximum ROI and higher
utilization rates. Construction companies
also benefit from a reduction in the
number and types of compressors they
need to own. The Mid-Range Series
provides different pressure/flow options
at different times, eliminating the need to
rotate compressors on a jobsite.”
The series gets a 7 in. Sullair

With so much of the recent news
focused on the development
of electrification technology and other
power system alternatives, it’s worth
remembering that even under the most
optimistic electrification scenarios,
combustion engines are going to be
around for quite some time. In all
likelihood, decades.
As such, while much engineering time
and money have been poured into all
things “e,” there are still any number
of suppliers that continue to invest
in the further refinement of critical
engine technologies. A good example is
Stanadyne.
Beginning as a machine shop more than
140 years ago, Stanadyne has specialized
in diesel engine fuel system technologies
since the 1950s. Over the last five years,
the company has invested in both its
technical capabilities and facilities, with
an eye toward continued refinement of
combustion engines.
“Some of our competitors have made
public announcements that they are
reducing their emphasis and investment
in high pressure or any kind of fuel
injection system as the world moves
towards electrification,” said Dr. John
Pinson, president of the Windsor, Conn.-
based company. “We saw an opportunity
to take advantage of some of this
whitespace that’s opening up with the exit
of part of our competitive base.
“We think there is a lot of runway left
in both gasoline and diesel fuel systems
and the rate of innovation is just as
breathtaking today as it was 20 years
ago when it seemed like we were getting
near the top of the S-curve. It just hasn’t
happened yet and it’s astounding what
we’re able to do today that we could not
conceive of 10 years ago. We still see
a great need for innovation in internal
combustion engines.”
STRATEGIC INVESTMENTS
That sentiment is more than just lip
service, as the company has continued
to strategically invest in technology and
facilities. In 2016, it opened its Sharjah,
U.A.E., plant, which has a production
capacity of 3000 rotary diesel fuel pumps
per month. That production is dedicated >

to Millat Tractors Ltd., an agricultural
tractor manufacturer in Lahore, Pakistan.
Capacity was expanded in 2020 to
6000 units to support additional global
OE and service part demands from
Americas, European and emerging market
customers.
In 2017, it established a strategic
alliance with Chinese fuel system specialist
BYC through which it has developed
high pressure common rail fuel systems
for engines up to 800 hp built in China.
Later that same year, the company opened
a Center of Excellence for common rail
systems in Suzhou, China.
In early 2019, the company acquired
PurePower Technologies, a supplier
of new and remanufactured diesel fuel
injectors for OEM and the aftermarket
and aftermarket applications.
Then in mid-2020, Stanadyne formed
a strategic partnership with Liebherr
Components, one of the world’s largest
Stanadyne has continued to
invest in advancing combustion
engine technology through
products such as its common
rail diesel fuel pumps.

manufacturers of construction machines,
to supply, distribute and service integrated
diesel fuel injection systems for on-and
off-highway engines.
LOOKING TO THE FUTURE
Finally, last October, Stanadyne opened
a new Research and Customer Service
Center in Southfield, Mich., where it will
carry out engineering and sales activities
surrounding fuel injection systems.
“The mandate we’ve had has been
to figure where should Stanadyne be
growing for the future,” said Pinson, “and
then design and sell those products so that
we can continue to be a vital influence in
the industry.
“One of the things we did is invest in
diesel common rail technology and our
large facility in China has grown a really
thriving business in high pressure diesel
common rail pumps. We also have the
strategic partnership with Liebherr and
they and a number of other partners are
driving hard and growing quickly in the
diesel common rail space.
“Recent troubles in the automotive
diesel space notwithstanding, the
technology on the commercial diesel side
is absolutely rock solid. If you look at the
injection pressures we’re pushing now,
2500 bar is quite commonplace and we’re
pushing ever higher and getting emissions
compliance capabilities and drivability
and performance that once would have
been hard to imagine.
“We have also been, in the U.S.,
diversifying into high pressure gasoline
fuel injection. Starting in 2013, we
have been producing about a million
high pressure gasoline injection pumps
for GDI systems for the U.S. and the
America’s markets since 2013. That’s just
been a very strong business.”
GROWTH OF GDI
While used primarily in passenger cars
and light commercial vehicles, Pinson said
GDI (gasoline direct injection) promises
to ultimately transform all gasoline engine
markets, including smaller engines used
in commercial applications, Pinson said.
“I think that the era of non-electronic fuel
injection system engines is fading very
quickly,” he said. “If we take a look at
the growth rate of GDI within the overall
gasoline engine world, it’s taking more
and more share of the total market. Every
year it’s growing by double-digit CAGR.
“And the systems are becoming much
more cost-effective. When they started
out, they were very expensive, to the
point of being prohibitive – that’s why
initially you saw them up in just high-
performance vehicles. Now you’re seeing
them get all the way down into really
small engines, and I wouldn’t be surprised
at all to see them in work tools and
things like that because they offer such
a tremendous fuel economy benefit and
performance benefit.
“There are also emissions regulations
coming to those smaller engine segments
and sooner or later, GDI technology
could become the cheapest way to address
those concerns.”
ROLE IN ELECTRIFICATION
And for any who might think Stanadyne
is being shortsighted in its focus on
combustion engines, Pinson indicated
that the company is hardly ignoring
electrification.
“I never want to be that guy getting out
there in the rainstorm with the umbrella
saying, ‘It’s not gonna rain!” he said. “I
completely understand the enthusiasm
about electrification. It’s going to grow
rapidly and it’s going to bring new
features that we’ve not had in the past.
But it’s going to require considerable
innovation and Stanadyne sees an
opportunity to compete by providing
innovative solutions for the future.
“The way we define Stanadyne – wholly
or through partnerships – is that we
design and manufacture price-competitive
vehicle and powertrain pumping,
injection, air management and control
solutions. That’s what we’re focused
on – it’s pumps, it’s injection, it’s air
management, it’s control solutions. That
does encompass electrified vehicles.
“We very specifically have taken
the initiative to broaden our scope to
include that. The acquisition of Pure
Power has given us given us turbocharger
technology, injector technology and we
already had pumping technology. We’re
moving aggressively in all of those areas
with the thought to not only be there for
IC engines, but also the overall electrified
powertrain.
“At some point, there’ll be a
tipping point. We think that there are
opportunities within our scope would
help facilitate and help our customers
make the transition to electrification. And
we plan to be right there with them.” ■

electronic rotary and mechanical
rotary fuel pumps, Stanadyne
also manufactures fuel injections
components through its Pure-
Power Technologies subsidiary.

HEAVY-DUTY TRUCKS
APRIL 2021 | DIESEL PROGRESS | 37
Peterbilt Motors Co., the Texas-
based division of Paccar, has
unveiled a new flagship to its heavy-
duty Class 8 truck range. Five years
in development, Peterbilt said its new
Model 579 is the most advanced and
aerodynamic truck in its 82-year history
and brings new levels of efficiency and
fuel economy to the long-haul trucking
industry.
“In 2012, we unveiled our current on-
highway aerodynamic truck, the Model
579,” said Jason Skoog, Peterbilt general
manager and Paccar vice president. “The
579 was a brand-new clean sheet design
based on an entirely new robotically
assembled all aluminum cab platform.
“The truck we are introducing is the
result of five years of relentless focus
on improving uptime, increasing fuel
economy, and taking driver comfort to
new heights.”
The new Model 579 includes a range
of new aerodynamic features, the result
of more than 1000 hours of computation
fluid dynamics (CFD) analysis, that
the company said leads to significantly
improved fuel economy. These include
a lower, narrower hood intended to
improve airflow airflow over the top ana
around the sides of the vehicle. A new
A-pillar fairing redirects airflow around
the windshield and new sculpted mirror
heads and mirror arms now positioned on
the cowl. A redesigned air dam improves
aerodynamics while maintaining ground
clearance and the ground skirts have
been optimized, as have new tandem
axle fairings and wheel covers that are
designed to withstand road debris. New
tip-out chassis fairings also add to the
aerodynamics, while allowing easy access
to chassis components and full removal
without the need for tools.
“There were over 7.8 million CPU
hours used in order to make sure this
product was the most aerodynamic
product,” said Scott Newhouse, Peterbilt’s
chief engineer. “There were more than
300,000 hours of just engineering time
and that doesn’t even count the amount
of time by our testing and validation
engineers, and by our customers, who also
helped us validate the product.” >

Model 579 truck offers up
to 7% fuel economy improvement.
By Mike Brezonick
PACCAR POWERTRAIN
Along with the aerodynamics, Peterbilt
said the fuel economy improvement is
also the results of an integrated Paccar
powertrain that incorporates, engines,
transmissions and axles. Either of two
Paccar MX diesel engines are available,
the MX-13 and MX-11.
The MX-13 is an inline six-cylinder
engine with bore and stroke dimensions
of 130 x 160 mm and an overall
displacement of 12.9 L. The engine is
available with ratings from 405 to 510 hp,
with torque ratings from 1550 to 1850
lb.ft. at speeds from 900 to 1000 rpm.
The MX-11 is a 10.8 L (bore and stroke
of 123 x 152) inline six-cylinder engine
with ratings of 355 to 455 hp with torque
of 1250 to 1700 lb. ft., all at 900 rpm.
The engines incorporate an
aftertreatment system that includes a
diesel particulate filter (DPF) and selective
catalytic reduction (SCR) system. DPF
regeneration is typically passive, but
an active regeneration can be initiated
through a switch in the cab when the
truck is parked.
Peterbilt Motors Co.’s newest
Model 579 truck offers new
aerodynamics and a Paccar
powertrain to provide significant
improvements in fuel economy.

38 | DIESEL PROGRESS | APRIL 2021
The engines drive Paccar’s proprietary
12-speeds forward, two reverse automated
transmissions. Input torque capacity is
1850 lb.ft., with a low cruise speed of
1100 rpm. Incorporating an aluminum
housing and coolerless lubrication system,
system weight, including clutch and
oil, is 657 lb., which Peterbilt said is
105 lb. less than comparable automated
transmissions.
The powertrain also incorporates
a Paccar forged steel beam front axle
available in weight ratings of 20,000 and
22,000 lb. and Paccar tandem rear axle
with a gross combined weight rating of
80,000 lb.
Peterbilt said the new Model 579 truck
can also be specified with Cummins X15
diesel and X12N natural gas engines
and Eaton automated and manual
transmissions.
BETTER MILEAGE
Between the efficiency of the powertrain
and the aerodynamic enhancements,
the new Model 579 offers a significant
fuel economy improvement over its
predecessor. “These improvements will
deliver up to a 7% fuel economy gain on
a like-for-like basis for a linehaul sleeper
application compared to a current model
579,” Skoog said. “This is not funny
math, where you start with a truck with
no aero features, and then add the aero
features and then you get to the 7%.
We’re talking 7%, apples to apples.
“At a diesel cost of $2.50 a gallon
and driving 100,000 miles per year
that translates into an annual savings of
$2000. That will total up to $8000 over
an average trade cycle of four years.”
The aero design also improves driver
visibility as the hood, which is constructed
of Metton engineered plastic, is narrower
with a lower crown height to improve
forward sight lines. New LED headlights
are designed for better nighttime visibility
and better daytime conspicuity and
infrared heaters keep the headlight lens
clear in inclement weather.
Inside the cab the highlight is a new
15 in. Digital Dash Display, which is
engineered to deliver all the information
drivers need in a clean, intuitive design.
The display offers a fully customizable
user interface that can deliver a range of
digital gauges on the screen at any time.
Three different Drive View Zones are
available. Minimized View shows only the
speedometer and tachometer for minimal
driver distraction. Basic View includes
air and oil pressure, fuel and DEF levels,
water temperature and speedometer and
tachometer.
The Enhanced View displays the
maximum number of gauges from a list
of over 30 choices. Operators can fine-
tune the information shown to suit their
individual needs through controls found
on an all-new steering wheel.
Prior to trip departure the display
can provide a visual Systems Check,
inspecting 13 systems and providing
a green checkmark with each passed
test. The display also incorporates the
Digital Vision System, which provides
camera-enabled visibility around the
truck at all times, including at night and
during inclement weather. The display
system also interfaces with the Bendix
Fusion Advanced Driver Assistance
Systems (ADAS), which include collision
mitigation, lane departure warning and
the new lane keeping assist (LKA).
“The pre-production trucks had very
high praise for the Digital Display,” said
Skoog. “We’re also announcing that every
conventional Class 8 Peterbilt truck will
now include this new display.”
Peterbilt said it had 59 customers were
involved the design and helped record
more 1.5 million test miles, Available for
order in a day cab and a range of sleeper
configurations, the truck is built at the
Denton facility. ■

Along with diesel common rail,
electronic rotary and mechanical
rotary fuel pumps, Stanadyne
also manufactures fuel injections
components through its Pure
Power Technologies subsidiary.
The new 15 in. Digital Dash Display is engineered to deliver all the
information drivers need in a clean, intuitive, customizable interface.

A look at the latest developments
in marine vessel technology.
TIER 4 APPROVAL FOR
MTU MARINE ENGINES
Rolls-Royce announced it has received
EPA Tier 4 certification for its mtu
marine propulsion systems based on its
Series 4000 M65L 16-cylinder diesel
engines.
“This means we have climbed to the
king’s class of emissions regulations with
our engines for yachts and commercial
vessels,” said Denise Kurtulus, head of
marine business at Rolls-Royce’s Power
Systems division. “I am pleased that we
can now offer our customers these clean
and powerful propulsion packages.”
Through further developments in
turbocharging, combustion and fuel
injection, combined with the new mtu-
SCR exhaust aftertreatment system,
Rolls-Royce said it reduced NOx
emissions by 75% compared
to IMO II requirements
and particulate emissions
by 65% versus compared to
EPA Tier 3 without the use of
a diesel particulate filter. Fuel
consumption has also been reduced
compared to the previous generation
of engines and engine power to up to 214
hp (160 kW) per cylinder.
Rolls-Royce also announced it is
supplying two mtu 16V 4000 M55RN
gas engines to Sembcorp Marine
Integrated Yard for the construction of
the world’s first liquefied natural gas
(LNG)-hybrid powered tug. The harbor
tug will be operated in Singapore by
Jurong Marine Services, a subsidiary
of Sembcorp Marine. The new LNG-
hybrid, expected to be completed later
this year, is the first of 12 tugs that
Sembcorp Marine plans to build to
replace existing diesel-powered vessels
between now and 2025.
The main propulsion system of the
tug comprises twin 16-cyclinder mtu
Series 4000 gas units which will provide
EPA Tier 3 without the use of
a diesel particulate filter. Fuel
consumption has also been reduced
compared to the previous generation
of engines and engine power to up to 214
