设计了LPG发动机电控系统,制订了LPG发动机基本控制策略,通过试验对比了LPG发动机和汽油机的各项性能.试验结果表明:LPG发动机在动力性上相对汽油机有3.5％左右的下降,但经济性提高了大约4％；CO和HC排放均有明显降低,NOx排放略有降低.%The electronic control system of LPG engine was designed, the basic control strategy was formulated, and finally the performance between LPG engine and gasoline engine was compared by the experiment. The results show that, compared with gasoline engine, the power performance of LPG engine decreases by about 3. 5% and its economy performance improves by approximately 4%. Besides, the CO and HC emission of LPG engine reduce obviously and its Nox emission reduces slightly.
