Our generation isn’t getting pure air and a major cause of air pollution » is diesel engines. Diesel engines » emit many dangerous gases and lessened purity in air, Which is very harmful for us. Now we are upgrading our technologies and using [DG engines], which are a combination of electric & diesel to control air pollution. Retrofit technologies are filtering specific particles up to 90% which are the causes of air pollution. Diesel emission reduction technique is basically a combustion chamber design which uses an electric fuel system etc. There are mainly 2 types of systems to control the air-injection system and the exhaust gas recirculation [(EGR)] system. Other hand we have more missions like-
There are mainly 3 Auto emission missions, Which are evaporative emissions, refueling losses, and exhaust emissions.
[There are basically four methods of producing electronic emission.
Thermionic Emission, Photoelectric Emission, Secondary Emission, Field Emission.to control pollution.]
