重卡柴油发动机超速故障原因与分析

Cause and Analysis of Heavy Truck Diesel Engine Overspeed Failure

重型卡车发动机超速故障原因较多,大都是由于发动机喷油异常导致的,在正常行驶过程中还经常出现因司机误操作和低挡倒拖制动导致的超速现象。从超速机理和司机误操作等方面分析其具体原因,同时制定相关措施,以解决故障,提升整车运行可靠性。

There are many reasons for engine overspeed failure of heavy trucks,most of which are caused by abnormal engine fuel injection.In the normal running process,the overspeed phenomenon caused by driver's misoperation and low-grade backward towing braking is often encountered.This paper analyzes the specific reasons from the aspects of overspeed mechanism and driver's misoperation,and meanwhile develops relevant measures to solve the fault and improve the vehicle's operation reliability.
