| Abstract:The jacking mechanism of diesel engine is an important system to realize the function of intake and exhaust. In recent years many failure cases of jacking mechanism have occurred in the production and practive work of diesel engines. Aiming at four typical faults, this paper analyzes the failure phenomenon in detail, finds out the common cause of failure, and puts forward improvement and preventive measures, which is helpful to improve the reliability of jacking mechanism of diesel engine. |
