| 摘 要： | 针对LPG进气道气态喷射、进气道液态喷射和气缸内液态直接喷射对发动机性能的影响，进行了理论分析和在F170汽油机上的对比试验。试验结果表明：液态LPG缸内直接喷射发动机的最大扭矩比燃用汽油时提高约10％，能有效解决LPG常规供应方式发动机动力性下降的问题。

| Abstract: | In order to investigate the influence of port gaseous LPG injection, port liquefied LPG injection and liquefied LPG direct injection on engine performance, the contrastive experiment on an F170 engine and the theory analyses have been done. The result indicates that the maximum torque of the engine using liquefied LPG direct injection method is about 10% higher than that burning petrol fuel, and it is an effective way to solve the problem of the engine power deterioration with normal LPG fuel supply methods. |
