| 摘 要： | 本文根据调速特性线出现失速时的特点导出了失速段出现的判别式,并应用压力波传播原理阐明了低速失速区出现在针阀波形分界线上的机理。分别利用波形分界线方程及失速判别式两种方法来预测失速区,其结果与实测基本相符。

| Abstract: | A discriminant for appearance of diesel engine low speed discontinuity was deduced from the features of speed governing characteristic of diesel engine when speed discontinuity occurs. It was found that the low speed discontinuity region corresponds to the parting of injector needle lift wave curves. The speed discontinuity region was predicted by both wave parting and discontinuity discriminant and the results were in agreement with those of experiments by and large. |
