3. Engine is a device which transform one form of energy into another
form.
The six stroke engine “Using water” was developed
By Brush Crower in 2006.
A six stroke engine derived its name from the fact that it is a mixture
of two and four stroke engine.
The six stroke engine is a type of internal combustion engine based
on the four stroke engine , but its additional two stroke make it more
efficient and reduce emission.
Types of six stroke engines
1. Griffin six stroke engine.
2. Bajulaz six stroke engine.
3. Crower six stroke engine.
4. Velozeta six stroke engine.

6. The internal combustion is an
engine in which the burning of a
fuel occur in a confined space
called “ IC ENGINE’.
An external
combustion engine is
heat engine where
an(internal) working
fluid is compressed and
heated by combustion
of an external fuel
through the engine wall
or heat exchanger.

Alternators – it is used to convert the mechanical
energy into electrical energy.
Camshaft – it is used to controls the opening and
closing of valves.
Time belt – a belt connected to both camshaft
and crankshaft ensuring that they work in time
with each other.
Sparkplug – it is a component to initiate the
combustion process in spark ignition engine and
is usually located on the cylinder.
14. Fifth stroke
(secondary power stroke)

In this stage water is
injected by an Injector in the
form of fine droplets and the
water converted into steam.
Both valves are closed.
15. Sixth stroke
(secondary exhaust stroke)
At this stage water is
injected by an
Injector in the form of
fine droplets.
Exhaust valve open.

Engine With Four Stroke Engine

In otto cylce ,there
are two adiabatic
processes
1- Adiabatic
compression
2- Adiabatic
expansion
And
One constant
volume heat
Addition process
and one constant
17. 17t
The dual cycle
consist of the
following operations-
1- Adiabatic
Compression
2- Addition of heat at
constant volume
3- Addition of heat at
constant pressure
4- Adiabatic
expansion
5- ejection of heat at
constant volume
The heat is added partly at constant volume and
partly at constant pressure;
The advantage of which is that more time is
available to fuel for combustion.

parameters Four stroke engine Six stroke engine
Strokes It consist a 4 strokes . It consist a 6 strokes .
( add 2 additional strokes)
Thermal efficiency Low high
Weight Low High
Fuel consumptions High Low
Power Low High
Example- Car ,buses etc. Motor boat, high cost bikes(ex –Ducati).
19. Advantages of six stroke
engine
The thermal efficiency reaching 40-50%.
Fuel consumption reduce by more than 40%.
Reduction of chemical, noise and thermal pollution.
Increased torque and power output.

20. Disadvantage of
six stroke Engine
Complex Head Design
Complex Cam Design For Exhaust
(Due to two exhaust strokes).
Heavier Engine
(Due to combustion engine).
Manufacturing of essential part is difficult.
Weight increases.

21. conclusion
In a six stroke engine the fuel consumption is
less.
Better fuel economy compared with a conventional
four-stroke design.
Torque is increase by 35% and efficiency increased
by the same.
It reduces the weight and complexity of the
engines head by as much as 50%.
The concept of Six Stroke Engine seems to be
rather eco-friendly and low fuel consuming which
can fulfill the needs of near future.
