摘　　要：对发动机燃用LPG(液化石油气)-柴油双燃料时,喷油提前角的变化对发动机有害排放物数量和动力性能的影响进行了研究。试验结果表明:喷油提前角为7°左右时,双燃料发动机的综合排放性能最好,碳烟的排放水平较原发动机有明显的降低,同时发动机功率没有出现太大的损失。A research program is conducted to determine the effect of advance injection angle's varieties on exhaust emission and the power performance of LPG-diesel dual-fuel engine.The experiment results show that when the advance injection angle is at about 7?°,the general exhaust emissions performance is the best.The soot has reduced remarkably comparing with the original engine and the power of the engine does not lose distinctly.
