摘　　要：本试验通过对燃烧生物柴油对发动机排放污染物的测量和分析,探讨了生物柴油降低柴油机排气污染物的机理。研究结果表明:在同一稳定工况下,随着生物柴油加柴油中入比例的上升,燃烧排放物中的CO和HC比柴油排放呈现线性下降,NOx排放有所上升,而CO2排放一本在同一水平。The characteristics of exhaust emissions with different types of bio-diesel was studied. The pollutant formation mechanism of bio-diesel fuel was discussed. The experimental results show that Bio-diesel behaves the same thermal efficiency as that of petroleum diesel. Under steady working conditions, CO and HC emissions decrease linearly with the increasing of the ratio of bio-diesel in petroleum diesel, while NOx emission increases slightly and the specific CO2 emission is kept an almost the same level.
