摘要 通过改造一台压缩比为16 . 5的2 - 135柴油机,在其上实现DME的HCCI燃烧方式。试验结果表明,DMEHCCI发动机不但可以实现无烟燃烧,而且可以有效控制发动机NOx排放,使其接近0排放。在试验负荷范围内,CO排放随负荷增加而降低;HC的排放随负荷变化不大。 A 2-135 diesel engine with a compression ratio of 16.5 was modified t o a DME HCCI engine. The experiment results showed that DME HCCI engine not only realized smokeless combustion, but also presented almost zero NOx emission. Wi t hin the engine load range, the emissions of CO decreased with the increase of en gine load, while the HC emissions didn't change much with the variation in engin e load.
