车用直喷式柴油机低速稳定性研究

An Investigation in Stability of the Vehicle DI-Diesel Engine at Low Speed

本文通过对柴油机供油系统的匹配试验，分析了车用直喷式柴油机产生低速不稳定现象的原因，着重阐明异常喷射的机理；最后，提出了改善不稳定喷射的措施。

Matching experiments of fuel injection system have been carried out to investigate the unstable operation of a Dl-diesel engine running at low speeds. In this paper, the important factor causing unstability for the engine is expounded, the mechanism of abnormal fuel injection is mainly illuminated, and finally certain countermeasures are presented.
