当前汽车工业中,内燃机是重要的汽车动力源,燃料燃烧均会留下有害的残留物,例如炭烟颗粒(PM),我国新颁布的《中华人民共和国大气污染防治法》对在用机动车尾气排放提出了更加严格的要求,世界各国也均制定了更加严格的排放法规,以降低汽车尾气排放对环境的污染。柴油发动机尾气排放因大众公司的“尾气门”事件,更是引发全球密切关注。柴油机有害颗粒物排放始终是汽车工程师们关注的焦点之一。目前,欧洲甚至全球均颁布了非常严格的汽车尾气排放标准,由欧洲经济委员会(ECE)的汽车尾气排放
In the current automotive industry, internal combustion engines are an important source of automotive power. Fuel combustion leaves behind harmful residues such as soot particles (PM). The newly promulgated Law of the People’s Republic of China on Prevention and Control of Atmospheric Pollution affects the use of motor vehicles Tail gas emissions have put forward more stringent requirements. All countries in the world have also formulated more stringent emission regulations to reduce the environmental pollution caused by tail gas emissions. Diesel engine exhaust emissions due to Volkswagen’s “tailgate” incident, it is caused by close attention around the world. Diesel emissions of harmful particles has always been the focus of automotive engineers. At present, Europe and even the world have promulgated a very strict vehicle exhaust emission standards by the European Economic Commission (ECE) vehicle exhaust
