doi:10.3969/j.issn.1000-1093.2015.12.002

Abstract

Abstract: For the reliability problems of diesel engine in plateau area, such as cylinder head ablation and so on, the simulation investigation is made on the maximal fuel supply of injection pump and the different structures of injector nozzle. The effectiveness of the method to control the thermal load of engine in plateau environment is verified by adjusting the fuel supply parameters without modifying the engine structures. A plateau adjustment scheme of fuel supply system is presented, which includes decreasing the largest supply of the fuel pump properly, increasing the number of the jet holes, and reducing the diameter of jet holes and the spray angle of injector, by performance optimization experiment. The proposed scheme can be used to reduce the heat load of diesel engine and improve the reliability of diesel engine in plateau environment. The results show that the power output of diesel engine is dropped by 27% at high altitude of 4 500 m, and other control parameters are in the limited range.
