燃料在汽车发动机汽缸中有时不能充分燃烧,即出现所谓缺火现象,这时,燃料会在尾管或催化转化器中燃烧,造成对催化转化器的损伤。催化转化器是用来将一氧化碳、氮氧化物等有害气体转化成无害的二氧化碳、氮气和水的装置,它的损害会引起汽车尾气的污染。美国Purdue大学的研究人 Sometimes the fuel can not be fully burned in the engine cylinder of a car, that is, the so-called lack of fire occurs. At this time, the fuel burns in the tail pipe or the catalytic converter, causing damage to the catalytic converter. Catalytic converter is used to carbon monoxide, nitrogen oxides and other harmful gases into harmless carbon dioxide, nitrogen and water devices, its damage can cause automobile exhaust pollution.
