3. How to reduce Air Pollution:
Increasing amount of air reduces
incomplete combustion projects
Use of appropriate A/F ratio
Engine should be maintained properly.
A catalytic converter is a device which is
placed in vehicle exhaust syetem to reduce
HC & CO by oxidising catalyst & NO by
Reducing agent
Rhodium is best Catalyst to control NOX
keeping A/F ration within 14.6:1 to 14.7:1
4. Idling:
Idling is running a vehicle's engine when the vehicle is
not in motion.
Acute Effects:
Neurophysiologic: nausea
Respiratory
Cough, phlegm congestion
Immunologic: allergic or asthma
Decreased Lung Function
Engine idling produces several pollutants that are monitored
by the Environmental Protection Agency (EPA)
Children are also more susceptible, due to their faster breathing rate and the
fact that their respiratory system is still developing.
5. Conclusion:
An internal combustion engine is compact and lighter
An internal combustion engine can be started immediately
An internal combustion engine has higher efficiency than external combustion
engine
Each type of engines has some advantages over the other one. Thus, the selection
of the appropriate engine requires determining the conditions of application.
A vast research has to be done in this sector to:
More Efficiency
Less Fuel Combustion
Least Pollution
Use Bio Fuels
A European Union-funded project, called ‘New integrated
combustion system for future passenger car engines’, or ‘NICE’,
aiming to develop a new integrated combustion system.
