摘　　要：研究了不同山茶油生物柴油比例混合燃料的热重特性,并在R180柴油机上进行试验,分析比较了柴油机的经济性和排放特性。结果表明:生物柴油与柴油混合性良好;不同燃料的热重特性基本相同;柴油机动力性没受明显影响;与柴油相比,混合燃料的当量燃油消耗率略为增加;CH排放降低;CO排放在中低负荷时降低,高负荷时增加;NOx排放在中间转速时随着生物柴油比例的提高先增加后降低,高速时降低。研究证明山茶油生物柴油用于柴油机具有良好的替代柴油、减少排放的效果。Biodiesel/diesel mixed fuels with different mixing ratios are analyzed by thermogravimetic analyzer. A R180 diesel engine is fueled with the fuels and its economies and emissions are measured and compared. The results indicate that： camellia oil biodiesel can be mixed with diesel well; diesel engine power outputs have no significant changes; fuel consumption of mixed fuels is a little more than diesel; HC emission decreases; CO emission decreases at low- medium loads but increases at heavy loads; NOx emission increases at first and decreases at end at moderate speed but decreases at high speed. The research shows biodiesel presents a good effect on diesel substituting and emission reduction.
