Cause and Analysis of Heavy Truck Diesel Engine Overspeed Failure
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.
