The Engine Can not Start and Toyoda Camery Analysis of Difficult Starting Fault Diagnosis

电子技术的飞速发展和汽车相关法规(节能、安全、排放)的建立,促进了汽车控制技术的形成与发展,作为汽车重要组成部分的发动机已进入了电子控制的时代。汽车发动机电控技术在给发动机带来了控制的精确性、系统的稳定性、燃油消耗的经济性和排放的环保性等优点的同时,也给发动机故障检测诊断带来了困难。针对这一问题,深入研究了汽油发动机电子控制系统的检测诊断,为轿车发动机故障检测诊断提供参考。

the rapid development of automobile electronic technology and related laws and regulations （energy saving, safety and emissions） to establish, promote the formation and development of motor control technology, as an important part of the engine of the car has entered the era of electronic control. Electronic control technology of automobile engine to engine brought about environmental protection and has the advantages of accuracy, system control stability, the consumption of fuel economy and emission of the engine at the same time, also to the fault detection and diagnosis difficult. Aiming at this problem, in-depth study of the detection and diagnosis of gasoline engine electronic control system, providing the reference for diagnosis of fault detection engine car.
