摘　　要：在Ricardo Hydra单缸柴油机上,采用一次主喷射+一次后喷射的方法进行了5组燃烧对比试验。示功图和缸内燃烧分析表明,两次喷射有效地延长了等压加热过程,平均有效压力得到较大的提高,NOx排放有一定幅度的下降。In the Ricardo Hydra single cylinder diesel engine, the comparison between combustion experiments was carried out by means of post injection following main injection. The indicator diagram and in-cylinder combustion were analyzed. The results show that the two injections prolong effectively the isobaric heating process, increase greatly the mean effective pressure and reduce the NOx emission to some extent.
