the ignition delay period became longer while the sustained combustion period became shorter.
柴油机使用混合燃料后,滞燃期延长,燃烧持续期缩短。
the results show that the start timing of combustion is advanced and the ignition delay period is shortened.
通过对燃烧特征参数的计算分析,发现生物柴油的燃烧始点有所提前,滞燃期缩短;
experimental results show that using hot egr can significantly reduce the maximum cylinder pressure and temperature and slightly increase ignition delay period and combustion duration.
试验结果表明:采用热egr能增大氢内燃机的滞燃期和燃烧持续期,显着降低缸内最高压力和温度;
although the ignition delay period of e-diesel was postponed, the combustion duration was shortened and the mean indication pressure was enhanced.
