Design Research of Intake Compensation Device for Improving the Dynamic Performance of Diesel Engine in Plateau Environment
The impact of plateau environment on working performance of diesel engine is greater, it is important to explore the research of power restoration of diesel engine in plateau environment. In this paper, the numerical simulation model of a whole diesel engine with high-power is established based on the GT-POWER software, and the accuracy of the model is verified by the bench test. Based on this, the best intake air amount of compensation of the engine are calculated with different conditions in plateau environment, the compensation intake device with the idea which the high-pressure air of the vehicle storage is introduced into the engine to restore the power is proposed, and the relevant hardware and software are designed. Through real vehicle tests show that the compensation intake device can improve the dynamic performance of diesel engine effectively, which provide a basis for diesel engine design and improving the applicability of the existing diesel engine of vehicles in plateau environment.
