nature : car exhaust emissions contain 150 to 200 species of harmful substances, such as CO, SO2, nitrogen oxides (NOx, mainly to NO), benzo [a] pyrene and other hydrocarbon compounds. Mainly from petrol, diesel and combustion products. Diesel combustion produces smoke and stench specific, a general grams of black smoke contains about 70 micrograms of benzo [a] pyrene. At least to control hydrocarbon compounds and CO reduction of 96% of emissions, a 75% reduction NOx, respirable particulate matter by 90%. Environmental protection departments have control automobile exhaust emissions stringent standards. This must change the combustion and to add appropriate fuel additives to increase the combustion of fuel; Cars Lead Lead Pollution Control; Improved engine, electronic injection technology for machine control and to increase the exhaust after treatment, such as exhaust gas purification installation of catalytic converters and other means to control the aircraft.
