尾气分析在电喷汽油发动机故障诊断中的应用

The application of exhaust analysis on the failure diagnose of elcetronic control gasoline engine

根据发动机的燃烧和废气形成原理,分析了发动机废气产生的机理,并根据发动机废气分析的规则,分析了发动机各系统存在故障时对尾气排放的影响,最后通过尾气分析测得的各项数据追踪发动机故障的原因,结合实例进行说明.

According to the theory of combustion engine and exhaust to form theories, analyzing engine exhaust produced by mechanism, and in accordance with the rules of the engine exhaust gas analysis, analysis of the engine system fault when the impact of emissions, and finally through the exhaust gas measured values of various tracking engine failure reasons and examples to illustrate.
