在一台满足欧Ⅳ标准的柴油机上，通过台架试验研究了地沟油制生物柴油和大豆油制生物柴油对发动机动力性、经济性和排放性能的影响。结果表明，相对于纯柴油，燃用地沟油制生物柴油和大豆油制生物柴油导致转矩分别下降2%~13.8%和0.4%~11.6%；有效燃油消耗率分别上升3.8%~18.5%和4%~17.8%；有效热效率变化均在-4%~8%之间；排气中的NOX排放量分别变化12%~69%和-9%~7%。燃用两种生物柴油后，排气中颗粒物的质量浓度下降，但数量浓度激增；燃用大豆油制生物柴油时排气中的微粒质量浓度和数量浓度都低于燃用地沟油制生物柴油时的排放量。在微粒粒径分布方面，燃用普通柴油时，排气中的微粒以集聚微粒为主，燃用地沟油制生物柴油和大豆油制生物柴油后，排气中的微粒以核模微粒为主。

Bench experiments were conducted to study power, fuel consumption and emission of a diesel engine fueled with illegal cooking oil biodiesel and soybean oil biodiesel. The results indicate that , com-pared to diesel fuel, when fueled with illegal cooking oil biodiesel and soybean oil biodiesel engine torque decreases 2%~13.8%and 0.4%~11.6%, fuel consumption increases 3.8%~18.5%and 4%~17.8%, both changes of effective thermal efficiency vary between-4%and 8%. NOX emissions varies 12%~69%and-9%~7%. Mass concentration of particulate matter of both biodiesel decreases, but the number concentration in-creases rapidly. Particulate size distribution changes from nucleation mode and accumulation mode coexist-ing to nucleation mode only.
