汽车排放污染控制技术 摘要：随着经济条件的迅猛发展，汽车在全国范围内已越来越普及，在人们交通越来越便利的同时，汽车尾气排放的污染也越来越成为威胁人们赖以生存的环境的主要途径之一。分析了汽车尾气的主要成分危害以及治理方法，对柴油机的一些故障诊断方法作了一些具体的分析，以及柴油机排气净化，机内、机外净化作了详细的研究，然后作出了对柴油机高压共轨多次喷射技术的改进，排气后处理技术的研究及发展进程等。最后提出了努力发展研制可替代能源的环保型汽车的一些方法和具体行动，为未来汽车污染的有效控制以及新一代更为环保型汽车指明了有效的途径。 关键词：排放；污染；控制 Steam emissions contamination control technique BIE Heng-Qi (Yangzhou Industry Polytechnic Institute, Yangzhou 225127,China) Abstract: A swift and violent exhibition, the steam is more popular in entire Fan Yiyue, in person transportation Vietnam more convenient same, steam exhaust emissionss pollution also more Cheng Weiren survives one of boundary main ways. Has analyzed the steam exhaust principal constituent harm as well as the government method, diesel engines some breakdown method has made some concrete analyses, as well as a diesel engine row of gasification, machine, the outside the aircraft has done the research, then made the diesel engine high altogether many times to shoot the technique changing, After the exhaust, principle technique research and exhibition regulation and so on. Finally proposed unfolds the development to be possible diligently the energy alternative to guarantee steam some methods and effects personally, not the steam pollutions active control as well as the new generation guaranteed the steam to indicate the effective way.
