摘要
随着全球空气污染加剧,控制柴油机排放污染物是解决污染的主要措施之一。柴油机排放污染物中的颗粒数(PN)不仅污染空气,还严重危害人们的身体健康。为了满足法规中PN的要求,分别从优化燃烧、优化活塞环组、优化油气分离器的分离方式、优化颗粒捕集器(DPF)四方面入手,提出了优化措施,并通过试验,验证了优化措施的可行性。
With the intensification of global air pollution,the control of diesel emission pollutants is one of the most important measures to solve the pollution.Particle number(PN)in diesel emissions not only pollutes the air,but also seriously endangers people's health.In order to meet the requirements of PN in the regulations,optimization measures are put forward from four aspects,namely,optimization of combustion,piston ring group,separation mode of oil/gas separator,and diesel particulate filter(DPF),and the feasibility of the optimization measures is verified through tests.
