    • PURPOSE: A malfunction diagnosis system of a vehicle using exhaust gas is provided to detect trouble due to the malfunction of an electronic control unit and a mechanical matter of an engine in itself. CONSTITUTION: A malfunction diagnosis system of the vehicle using exhaust gas includes an exhaust gas analyzing device(2) analyzing constituents of exhaust gas and outputting constituent ratio data of exhaust gas, a data storing unit(4) storing data of causes of error and constituent ratio of exhaust gas, a data processing unit(6) connected to the exhaust gas analyzing device and the data storing unit, and a display unit(8) connected to the data processing unit. The data processing unit searches data stored in the data storing unit if constituent ratio of exhaust gas is output from the exhaust gas analyzing device and outputs data of the cause of error against the constituents of the exhaust gas. The display unit displays data of the cause of error output from the data processing unit.
    • 目的:提供使用废气的车辆的故障诊断系统,以检测由于电子控制单元的故障和发动机本身的机械事件而引起的故障。 本发明提供一种使用废气的车辆的故障诊断系统,其包括:废气分析装置(2),其分析废气的成分并输出废气的构成比数据;数据存储单元(4),其存储错误原因和成分 废气比率,连接到废气分析装置和数据存储单元的数据处理单元(6)以及连接到数据处理单元的显示单元(8)。 如果从排气分析装置输出排气的构成比,则数据处理单元搜索存储在数据存储单元中的数据,并将错误原因的数据与排气的成分进行输出。 显示单元显示从数据处理单元输出的错误原因的数据。
