尾气分析在发动机故障检测中的应用

汽油发动机工作情况与燃烧质量有直接关系，而发动机尾气可反应混合气的燃烧质量。通过检测和分析发动机不同工况下尾气的成分，可以判断发动机各系统是否正常，也可以据此对汽油发动机系统进行故障诊断。文中介绍混合气的燃烧过程、废气的生成、利用发动机尾气分析结果对发动机各系统进行故障诊断的方法。

Research on Exhaust Gas Analysis and Checking and Measuring of the Engine's Malfunction

The working condition of gasoline engine has direct relation with combustion quality, and exhaust gas of the engine can reveal combustion quality of the mixed gas.Through measuring and analyzing different operating modes of the engine make the composition of the exhaust gas,we can judge whether every system of the engine is normal or not,and hereby we can also diagnose the malfunction of the gasoline engine system.This paper introduces the combustion process of the mixed gas,the formation of the exhaust gas...
