Jiang Xiaojun

Abstract：With the increase in the number of motor vehicles， the problem of automobile emission pollution is becoming more and more serious. How to control the environmental damage of automobile emissions has become an important task faced by relevant R&D personnel. The automobile engine system is related to the quality of the automobile. Strengthening the fault diagnosis of the engine system can effectively reduce the failure rate. It is an important research topic for automobile fault diagnosis and maintenance to ensure that automobile engine failures are issued in time to warn and detect as soon as possible， so that automobiles can work under the regulations of the national standard， and to reduce air pollution. This article describes the structural composition of the automobile engine system， analyzes the malfunctions of the automobile engine， and proposes the application of modern detection technology in the maintenance of automobile engine failures.
