Emission Control on IC Engine
The pollusion problems in our country are increasing day by day. Euro 2000 norms came to reduce the pollusion problems. Now a day LPG vehicles are more preferred due to this reason.
Atmospheric pollusion from automobiles mainly occured from the fuel tank, the carburattor, the crank case and the exhaust system. One of the main method to reduce pollusion from engine is to introduce positive crankcase ventilation valve (PCV valve) in between the crankcase and intake manifold. Other methods to reduce pollusion from different parts are
1. Closed crankcase ventilation
2 Fuel tank and carburattor ventilation
3. Re-designing the engine
a. Combustion chamber
b. Cooling system
c. Fuel supply system
d. Ignition system
4. Treating the exhaust gases to reduce pollutants
5. Exhaust gas analysis
