| 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。

| Abstract: | 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. |
