摘　　要：在一台直喷式增压柴油机上研究了生物柴油发动机的HC,CO,NOx,PM和烟度等常规排放特性,同时基于美国环保署TO-11A方法,利用2,4-DNPH管采样,采用高效液相色谱分析仪分析了醛酮类化合物的排放特性。试验结果表明:生物柴油能有效降低HC,CO,PM及烟度排放,但增加了NOx排放;与柴油相比,生物柴油的醛酮类化合物排放从30.7mg/kW.h上升到90.8mg/kW.h,增加了2倍。The regular emission characteristics of biodiesel engine were carried out on a direct-injection,turbocharged diesel engine,such as HC,CO,NOx,PM and smoke emissions.Based on the TO-11A methods of USA EPA,the emission characteristics of carbonyls were also analyzed by 2,4-dinitrophenylhydrazine(DNPH)-coated silica cartridges sampling and using High Performance Liquid Chromatography(HPLC).The results indicate that biodiesel can reduce the HC,CO,PM and smoke emissions of diesel engine,however,the NOx emissions are increased by using biodiesel.Compared with diesel,biodiesel increases the carbonyls emission from 30.7mg/kW·h to 90.8 mg/kW·h.
