The continuous development of automobile electronic products is an important symbol in the car used more widely. In the environmental impact is taken seriously more and more today, automobile pollution problem has attention, but because of its low electronic-controlled engine emission pollution, good performance and fuel economy has become an indispensable part of automobile engine. The main components of air flow, the inlet temperature sensor/inlet pressure sensor, temperature sensors, oxygen sensors, knock sensor, comprehensive type throttle position sensor, the camshaft position sensor, crankshaft position sensor, idle, injector valve. This paper mainly introduces the main above electronic-controlled engine sensor, the actuator fault phenomena and detection methods. Keywords: air flow, comprehensive type throttle position sensor, the temperature sensor, oxygen sensor. 目录 摘要···································································3 目录绪论 1.1发动机电控技术的发展··············································7 1.2 电术对发动响8 第二章电控发动机传感器的检测············································9 2.1空气流量计························································9 2.2进气温传/进气压力传2.3水温传11 2.4氧传11 2.5爆燃传13 2.6综节门传14 2.7光电轮轴/轴传15 第三章 电发动机执检测16 3.1怠速控制阀16 3.2喷17 致谢19 参考文献··················································
