摘　　要：对一台轿车用柴油机燃烧低比例生物柴油的排放污染物进行了试验研究,分析了不同配比的生物柴油燃烧污染物随发动机转速、发动机负荷的变化规律。试验结果表明:生物柴油可以有效地降低柴油机的排气污染物,尤其是烟度污染物;随着生物柴油掺混比例的增加,烟度和THC污染物的排放呈线性下降,而CO和NOx排放物的变化受发动机的转速和负荷影响很大。The exhaust emissions of a car diesel engine are experimentally studied when diesel fuel is blended with low proportion of bio-diesel. The law of how the combustion pollutants of bio-diesel changes with engine speed and load is analyzed under different blending proportion. The results show that the bio-diesel fuel can reduce the emissions of diesel engine effectively, in particular, the soot pollutant. When the proportion of bio-diesel increases, the emissions of soot and THC pollutants will linearly decline. The engine rotation speed and load have large effects on the emissions of CO and NOx.
