摘　　要：在一辆柴油轿车上分别燃用纯柴油(D100)及其与体积分数10%的生物柴油、丁醇、天然气制油和煤制油混合而成的4种替代燃料(BD10、Bu10、G10、C10),采用EEPS颗粒物粒径分析仪进行了实际道路颗粒物排放试验。结果表明:试验车辆燃用4种混合燃料的颗粒物排放均比燃用纯柴油有所降低;燃用BD10和Bu10引起大粒径颗粒物排放量降低,燃用G10和C10则使各粒径范围颗粒物排放量整体降低;与D100相比,燃用BD10、Bu10、G10和C10时的全程颗粒物数量排放率分别降低了13.23%、29.28%、26.72%和1.89%,全程颗粒物质量排放率分别降低了25.93%、30.61%、17.16%和11.41%。By using a spectrometer EEPS-3090, an on-board measurement of particle emissions is carried out on real roads on a diesel car fuelled with pure diesel fuel and its four blends with 10% （ volume fraction ） biodiesel （BD10）, butanol （Bu10）, gas-to-liquid fuel （G10） and coal-to-liquid fuel （C10） respectively. The results show that compared with pure diesel fuel, the particulate emissions of the car fuelled with 4 blend fuels all reduce. Fuelling with BD10 and Bu10 causes the reduction in number emissions of large-size particles;fuelling with G10 and C10 leads to an overall decrease in particle number emissions within the whole diameter range;the average particle number emission ratio of BD10 , Bu10 , G10 and C10 in the total mileage of test reduce by 13. 23%, 29. 28%, 26. 72% and 1. 89% respectively; while the figures for particle mass emission ratio are 25. 93%, 30. 61%, 17. 16% and 11. 41%.
