摘　　要：通过对柴油机供油系统匹配试验的结果分析 ,阐明了车用直喷柴油机低速不稳定现象是由供油系统的异常喷射造成的 ,并进行了机理探讨。最后提出了改善不稳定喷射的措施。In this paper, matching experiments of fuel feed system have been conducted to expose the unsteadiness of the vehicle DI diesel engine at low speed,which was caused by abnormal injection of fuel feed system. Further more, the mechanisme of unsteady injection was explained. After all, measures are presented to improve the stability of DI diesel engine at low speed.
