摘　　要：奇瑞汽车是知名度较高的国产汽车,也是芜湖自主品牌。作为比较经典的奇瑞车型,目前芜湖市场奇瑞A3的保养量较大。从上市至今,一批车辆已经过了正常工作期,逐渐进入加速磨损期,故障率大大增加。发动机是汽车的核心,各大维修站都有遇到A3轿车发动机不能起动的故障。发动机要能正常起动必须具备三个要素:足够的气缸压缩压力、准确的点火正时及强烈的火花和良好的可燃混合气。如果某一要素异常便会引起发动机不能起动或起动困难故障。从故障现象、分析原因到排除故障,就是解决以上三要素的问题。而每个要素是否正常需要经过技术检测,确定技术参数是否符合技术标准。本文介绍了奇瑞A3轿车发动机无法起动故障的分析思路与诊断流程,总结了发动机不能起动故障的排除方法,对使用与维修奇瑞A3轿车有较高的现实的意义。Chery is a well-known domestic car,is also an independent brand of Wuhu.As a more classic Chery model,the current market in Wuhu Chery A3 maintenance volume.From the market up to now.A number of vehicles have passed the normal working period,gradually entered the accelerated wear period,the failure rate greatly increased.The engine is the core of the car.All the major maintenance stations have trouble starting the engine of the A3 sedan.To start the engine normally,the engine must have three elements:sufficient cylinder compression pressure.Accurate ignition timing and strong sparks and good combustible mixtures.If an element is abnormal,it will cause the engine to fail to start or start It is difficult to solve the above three factors from fault phenomena,analysis reasons and troubleshooting,which is to solve the above three factors.Whether each element normally needs to be detected by technology to determine whether the technical parameter meets the technical standard.This paper introduces the analysis thought and diagnosis flow of the failure of the engine of the Chery A3 car,summarizes the troubleshooting method of engine failure to start failure,and has a higher realistic meaning for the use and maintenance of the Chery A3 car.
