摘　　要：通过柴油机高原性能模拟试验,分析了柴油机的动力性、经济性随海拔高度的变化规律,以及高原环境对柴油机起动性能和热平衡性能的影响,提出了高原增压、供油系统调整及优化、低气压低温起动、热平衡控制、电控柴油机高原标定等提升车用柴油机高原性能的技术对策,为研究进一步提高柴油机的高原环境适应性提供了参考。The performance of diesel engine working in different altitude regions were studied by simulation test. The influence of the altitude on engine performance, such as power, economic, cold starting and thermal balance were verified,and some measures were put forward to improve diesel en- gine performance at plateau, such as boosting technology, fuel system improvement, cold starting, heat balance control, calibration for electronic controlled diesel engine. The purpose was to provide reference for improving plateau environmental worthiness of diesel engine.
