汽车排放的污染物占大气中总污染物的65％～85％,其中主要有害气体为HC、NOx和CO等。汽车排放污染物的多少与汽车各大总成的技术状况有关,在影响汽车排放污染物含量的主要总成中,燃油供给系统占30％,点火系统占26％,发动机其他方面占28％,底盘传动系统占16％。因此,减少汽车排放污染主要应对汽车进行及时维护。本文以五菱型汽车为例介绍降低汽车排放污染的日常性措施。
The pollutants emitted by vehicles account for 65% ~ 85% of the total pollutants in the atmosphere, of which the main harmful gases are HC, NOx and CO. The amount of pollutants emitted by vehicles is related to the technical conditions of the major automobile assemblies. Among the major assemblies that affect the emission of pollutants from vehicles, the fuel supply system accounts for 30%, the ignition system accounts for 26%, and the rest of the engine accounts for 28% Chassis drive system accounted for 16%. Therefore, to reduce vehicle emissions pollution mainly to the timely maintenance of the car. This article takes Wuling Automobile as an example to introduce the routine measures to reduce the pollution caused by automobile emissions.
