Title:Passat T electronic-controlled engine fault diagnosis and maintenance
Abstract:The rapid development of electronic technology and the establishment of the relevant laws and regulations, promote the formation and development of the auto control technology, as an important part of automobile engine has entered the era of electronic control. Automobile engine electronic control technology in brought engine control accuracy and the stability of the system, the consumption of fuel economy and emissions of the advantages of the environmental protection at the same time, also brought difficult to diagnosis of engine fault detection. This article is aimed at this problem deeply studied the passat T electronic-controlled engine fault diagnosis and maintenance.
This article expounds the passat T of electronically controlled engine control system basic position and working principle, analyses the passat T electronic-controlled engine electronic control system after a failure, how to make use of artificial and all kinds of instrument to detect the diagnosis. Passat T electronic control engine is mainly studied various mon faults (engine not starting, engine starting difficulty, idle speed, acceleration, the ignition abnormal) the failure phenomenon, failure reason and fault diagnosis method.
Keywords:Passat electronic controlled engine fault diagnosis
