摘要：

为满足对未来汽车发动机更加严格的排放法规和油耗标准，且降低成本，该文将汽油部分
扩散压燃模式和低辛烷值汽油相结合，在一台两缸常规柴油机上进行了实验对比。实验采用0# 柴油
和辛烷值46、56 的汽油，用FBY-2 型波许烟度计测量排气烟度，用AVL SESAM 4.0 多组分排放仪测
量气态污染物；测量并对比了发动机的油耗、烟度以及各种气态污染物的排放浓度等主要性能参数。
结果表明：汽油部分扩散压燃模式的燃烧速度加快，使油耗达到甚至略低于常规柴油压燃模式的水
平；高速高负荷时，碳烟排放显著降低；但总碳氢化合物排放明显高于常规柴油燃烧模式。

Abstract:

Partially diffused compression ignition mode was combined with low octane number gasoline to
meet the more strict emission and fuel economy standards in future, as well as to lower costs. Experimental
comparison was carried out based on a two-cylinder diesel engine fueled with low octane number gasoline and
conventional diesel fuel, respectively. Normal 0# diesel and gasoline with research octane number (RON) of 46
and 56 were tested. Smoke numbers were measured by FBY-2 Bosch smoke meter, and the gaseous emissions
were measured using AVL SESAM 4.0 multi-gas analyzer. Performance of fuel economy, soot emission and
gaseous pollutants were compared and analyzed to show that the fuel consumption is even lower than that
of diesel when burning low octane number gasoline due to a rapid combustion of the gasoline with the smoke
markedly reduced, especially under high load and high speed conditions; however, the total hydrocarbon (THC)
emission is higher than that of burning conventional diesel fuel.

Key words: combustion, gaseous emissions, partially diffused compression ignition, low octane number gasoline
