摘　　要：通过对燃烧生物柴油发动机排放污染物的测量和分析,探讨了燃烧生物柴油排气污染物的形成机理,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。研究结果表明:生物柴油可以有效的降低柴油机的排气污染物,尤其是颗粒污染物。随着生物燃料中油酸甲脂含量的增加,柴油机的各种排气污染物均有不同幅度的降低。此外,通过推迟喷油时间,可以进一步降低柴油机的NOx污染物。The characteristics of exhaust emissions with different mixing ratios of bio-diesel was studied. The pollutant formation mechanism of bio-diesel was discussed. The pollutant regulation of different mixing ratios of bio-diesel varying with engine rotation speed and load were also discussed. The optimal ratio of mixing bio-diesel was obtained from the study of engine emission under different working conditions. The experimental results show that the bio-diesel fuel can reduce its emissions effectively especially can decrease the particulate matter（PM）. When the bio-diesel ratio increases, the emissions will be decreased at different degrees. Retarding fuel injection timing can also reduce NOx and PM emission effectively for bio-diesel engine.
