Faults and Countermeasures of Plateau Engine Turbocharger
When the diesel engine is running in the plateau environment,due to the decrease of air density,the intake air volume decreases,which can easily lead to the damage of the turbocharger,white smoke and insufficient power.In this paper,the turbocharger fault of a certain type of off-road ChinaⅣ engine in plateau conditions is diagnosed,and the inlet position of the turbocharger bypass valve and the engine control strategy are adjusted and optimized by using the plateau environment simulation bench test.The results show that the high speed of the turbocharger in the plateau environment is the main cause of the failure.The optimized scheme effectively controls the speed of the turbocharger,improves the dynamic performance of the engine,verifies the feasibility of the optimization scheme,ensures the reliability of the plateau equipment,and provides a reliable basis for improving the performance of the plateau engine.
