摘要
静止的发动机进入工作状态,必须先用外力转动发动机曲轴,使活塞开始上下运动,气缸内吸入可燃混合气,并将其压缩、点燃,体积迅速膨胀产生强大的动力,推动活塞运动并带动曲轴旋转,发动机才能自动地进入工作循环。发动机的曲轴在外力作用下开始转动到发动机自动怠速运转的全过程,称为发动机的起动过程。完成起动所需要的装置叫起动系。通过发动机起动机的电路故障的检测和诊断的讲述。让我们知道起动系统的组成和其功用。并对起动系统的常见故障现象、故障部位、故障机理、故障的检测、诊断和排除有了一定的认识。明确了检测和诊断的基本思路。通过理论与实践结合,把起动系统常见的故障检测与诊断作了说明。通过实验掌握起动机的试验方法,掌握起动机不运转故障的判断排除方法,掌握起动机运转无力故障的判断与排除方法,以便于以后快速、准确地查找故障发生的原因和部位。

Abstract
Stationary engine to enter into a working state, must use external force to rotate the engine crankshaft, piston begins to move up and down, the cylinder bustible gas mixture, and pression, ignition, the volume of rapid expansion to produce strong power to push the piston motion, and drives the crankshaft to rotate, the engine can automatically enter the work cycle. The crankshaft of the engine under the action of external force began to turn to the automatic engine idling operation of the entire process, known as the engine's starting process. Finish start need device called a starter system. The engine starter circuit fault detection and diagnosis on. Let us know the starting system and its function. On the starting system of mon faults, fault location, fault mechanism, fault detection, diagnosis and exclusion of a certain understanding. The detection and diagnosis of the main train of thought. Through bination of theory and practice, the starting
