| Abstract: | There is a close relationship between the operating condition of a engine and the vent gas composition.the operating condition of a engine,air-fuel ratio,and ignition timing also have a direct influence on the content of HC,CO and NO x.In this paper,the anonaly of the vent gas composition is analyzed and the engine fault could fastly be diagnosed based on the correlation between the vent gas composition and the fault in a engine system. |
