Abstract: In order to improve the utilization of energy, reduce automobile fuel consumption and exhaust emissions of air pollution, the automobile engine idle start-stop technology has been widely used. This system can realize the intelligent start and stop of vehicle under the idle speed. In actual use, due to the various reasons, the engineer idle start-stop system cannot run, and the vehicle combination dashboard indicates that the idling start-stop function is abnormal. This paper analyzes the BESTUNE automobile engine idle start-stop system principle, and puts forward the fault diagnosis and troubleshooting methods.

引言
随着汽车节能技术的发展,越来越多的汽车发动机配备了怠速启停系统。发动机怠速启停系统能够有效降低燃油量、减少环境污染,避免发动机积碳问题[1]。然而发动机怠速启停系统功能复杂、故障时有发生,维修繁琐。下面就以奔腾B50手动挡轿车的发动机怠速启停系统为例,介绍其工作原理和故障诊断排除方法。
1 怠速启停系统概述
奔腾b50 发动机怠速启停系统是在整车短时间停止时控制发动机停止,并在驾驶员操作或者系统有需求时再次起动的智能控制系统。当遇到红绿灯或者堵车时,发动机怠速启停系统能够让发动机熄火;当驾驶员踩下离合器、油门踏板或松开刹车的瞬间,发动机启动。该系统通过传感器采集车辆运行状态信
