摘　　要：在经过改造的单缸柴油机上对PRF87、PRF93、TRF25这3种汽油替代物在中、低负荷时进行了低温模式的燃烧物排放研究。试验表明,TRF25在中、低负荷工况下的燃烧物排放特性与汽油吻合较好,且炭烟排放极低,体现出在低温燃烧模式下燃用高辛烷值汽油特性燃料在降低炭烟排放方面的巨大潜力。On a modified single cylinder diesel engine,the paper studied the combustion emission of low temperature model with PRF87,PRF93,TRF25 three gasoline substitutes at low and medium loads. The tests result show that at medium load,the combustion emission characteristics of TRF25 agree with that of gasoline,and smoke emission is extremely low. This proves that high octane gasoline in low temperature mode has a tremendous potential in reducing soot emission.
