摘要
汽车污染物来自排气管排出的废气、曲轴箱窜气和燃油蒸发等。恒温进气空气滤清器、二次空气喷射系统、催化转换器、排气再循环系统、曲轴箱通风装置及汽油蒸发控制系统等新型排气净化装置,可以抑制有害排放物的产生,使汽车排气得到净化。
Automobile pollutants come from waste gases exhausted from outlet,blow-by of crankcase and vaporization of fuel.New purifying apparatuses,such as air filter in constant-temperature inlet,second air-injection system,catalytic converter,exhaust recycling system,crankcase ventilation apparatus and gasoline vaporization control system can reduce the forming of harmful emissions to purify automobile emissions.
