摘要
针对四川省在用压燃式汽车尾气烟度排放情况进行了详细的调查研究，结果表明：四川省机动车颗粒物排放量中99．34％的颗粒物来自汽车排放，其中在用压燃式发动机汽车占到绝大比例。同时分析得出，实施“四川《在用压燃式发动机汽车加载减速法排气烟度限值》”标准可有效控制机动车排气烟度量，有利于四川省大气环境质量的改善。经预测采用加裁减速法及实施《在用压燃式发动机汽车加载减速法排气烟度排放限值》标准后，可使四川省汽车排气烟度削减率达到68．05％-95．92％。
This paper detailedly investigated particle emissions from in - use motor vehicles with compression ignition engine in Sichuan Province . The results showed that in Sichuan Province 99. 34% of the vehicle particulate matter emissions came from car exhaust, among which the in - use compression ignition automobile took the overwhelming proportion. After analysis, this paper put forward that implementation of the standard ＂ Limits for exhaust smoke from in - use vehicle equipped with compression ignition engine under lug - down test （LUGDOWN） ＂ is an effective way to reduce particle emissions of motor vehicle, and it helps to improve quality of atmospheric environment in Sichuan. Furthermore, it was predicted that by applying LUGDOWN and the standard the particle emissions from motor vehicle could be reduced approximately 68.05% - 95.92% in Sichuan Province.
