文档介绍：关于汽车尾气污染及其防治问题的研究
摘要
随着汽车工业的不断发展,汽车的保有量不断增加,汽车在给人类带来方便的同时,也对人们的健康和社会环境造成了危害。如何应对并能解决由于汽车保有量高速发展造成的大气污染,并且适应汽车燃料结构的调整,这正是世界各国急需解决的问题,而解决的最好办法,就是大力发展天然气汽车。
本文首先介绍了中国目前汽车尾气的排放情况,尾气的形成机理、化学组成以及相关的机内净化、机外净化、提高燃油品质和替代原料技术。然后分析了汽车尾气对环境的影响及其危害,并从治理汽车尾气的角度提出大气污染治理的措施与方案。最后对如何发展天然气汽车理论和实践中的主要问题进行了尝试性的研究,大力指出发展天然气汽车是解决汽车尾气对大气污染问题的最好办法,并在理论上及实际操作方面为人类环境保护和我国汽车业提供了参考与借鉴。

Abstract
With the development of automobile industry, the car retains the quantity increases ceaselessly; the car is in while the mankind brings convenience, but also on people's health and social environment harm. How to deal with and solve the car retains the quantity rapid development caused by atmospheric pollution, and adapted to the automobile fuel structure adjustment, it is world each country is badly in need of solving problems, and the best way to solve, is to promote the development of natural gas vehicle.
This paper first introduces the current situation of China automobile exhaust emission, emission mechanism, position and related internal purification, external purification, to improve the quality of fuel and alternative raw materials technology. Then the analysis of automobile exhaust on the environment 's influence and harm, and from the vehicle tail gas treatment of air pollution control measures and programs. Finally on how to develop natural gas vehicle in the theory and practice of main problem has made a tentative study to point out, develop natural gas vehicle automobile tail gas on the air pollution problem is the best way to, and in theory and practical operation for human environmental protection and China's auto industry to provide reference and use for reference.
Key Words: atmospheric pollution environmental protection
Vehicle exhaust natural gas vehicle
