摘　　要：摩托车使用中,经常出现供油不畅的问题,甚至熄火后很难再启动,有经验的维修人员会考虑到燃油开关及通往化油器的燃油开关是否发生故障。通过对摩托车熄火无法启动故障进行统计,基本上来自于燃油开关故障。因此,通过针对某摩托车燃油开关企业的三包退件进行统计,结合FMEA分析方法进行故障诊断,成功定位故障源。根据其失效模式采取相应的改进处理措施,最终解决燃油开关故障的漏油问题,为企业创造更好的经济效益。In the use of motorcycles,there is a problem of poor oil supply,and even it is difficult to start after a flameout.When it comes,experienced maintenance personnel will consider whether the fuel switch and the fuel switch to the carburetor have break down.By the statistical analysis of those failures,the problem basically stems from the fuel switch breakdown.Hence,Combined with analyzing three guarantees return of motorcycle from corporations of motorcycle fuel cock and the Failure Mode and Effects Analysis,this research successfully locates the source of trouble;furthermore,some actions based on the failure mode have been taking to solve the leak of fuel cock and the enterprise will gain much more benefits from this research.
