| 2. | The advantages of hcci are numerous comparing with the traditional engine . relative to si gasoline engines , hcci engines are more efficient , because they have no elimination of throttling losses , use the high compression ratios and have shorter combustion duration . relative to cidi engines , hcci engines have extraordinarily lower emissions of pm and nox and can offer more power as high as cidi engines with the dilute homogeneous air and fuel mixture
与传统的发动机相比均质压燃( hcci )具有很多优势:与火花点火汽油机相比, hcci发动机由于没有节流损失,压缩比较高,燃烧持续期短,其效率更高;与直喷柴油机相比, hcci发动机的碳烟和氮氧化物排放非常低,并且稀薄空燃混合气可以产生与柴油机一样高的功率。 |
