汽车尾气对环境的危害及其对策

针对汽车尾气污染日益严重的问题，以CO和PM2．5为例分析汽车尾气对人类及环境的危害。提出通过优化汽车设计、提高燃油品质、优化道路条件及开发新能源汽车等方案来解决汽车尾气排放对环境造成的危害。优化汽车设计以涡轮增压技术为例，采用涡轮增压技术的发动机可使汽车尾气中CO，NOx ，CH的含量较同款车型非涡轮增压发动机含量降低。

The Harm of Automobile Exhaust to Environment and the Countermeasures

Aiming at the problem that automobile exhaust pollution is more and more serious, and based on the present situation of automobile exhaust pollution, the authors analyzed the harm of auto exhuasted gas to environment,and took CO and PM2.5 as an example to explain the damage for human and environment as a result of vehicle exhaust.Four plans were put forward to deal with the environmental damage on account of increasingly serious automobile exhaust, which would optimize car design , improve the quality of the fuel, optimization of road conditions and exploit new energy vehicles.In the optimization of automotive design, a turbocharged engine could decrease the content of CO,NOx,CH in exhaust than general engines. Government regulation, cooperative enterprise and the whole people make common efforts to improve the environment damage due to automobile exhaust .
