汽车排放污染的控制技术探究

Research on the automotive emissions and pollution control methods

目前空气污染是我国急需解决的问题,而汽车尾气污染已经成为环境污染的重要因素,为了降低污染程度,提高空气质量,需要采用科学合理的技术控制汽车排放污染。目前可采用的技术有:直喷式燃烧系统、稀薄分层燃烧、多气门、可变气门正时和升程、废气再循环、催化反应器、微粒收集器、富氧燃料和燃油添加剂。

The current air pollution is an urgent need to solve our problems, and automobile exhaust pollution has become an important factor in environmental pollution, in order to reduce pollution levels, improve air quality, we need a scientific and reasonable technical control of vehicle emissions. The technology currently in use are： direct injection combustion system, stratified lean combustion, multi-valve, variable valve timing and lift, exhaust gas recirculation, catalytic reactors, particulate traps, oxygen-enriched fuel and fuel additives.
