尾气分析与汽油发动机系统故障诊断

Exhaust Gas Analysis and Fault Diagnosis of Gasoline Engine System

汽油发动机尾气成分直接与发动机的工作情况有关,对发动机在不同工况下尾气中不同成分气体含量的检测和分析,可以判断发动机各系统工作是否正常,也可以据此对汽油发动机系统进行故障诊断。本文介绍利用尾气分析结果对发动机各系统进行故障诊断的方法。

The ingredients of exhaust gas are related to the working condition of the engine. The detection and analysis of exhaust gas under different conditions can help us decide whether each system of the engine works normally and diagnose the faults of gasoline engine system. The diagnostic ways are introduced.
