| 摘 要： | 通过加装液化石油气(LPG)供给系统和设计LPG电控多点喷射系统,对295T型直喷柴油发动机进行了改装,并在相同条件下,以改装后的发动机为试验装置,分别燃用柴油和LPG/柴油双燃料进行了台架性能试验.试验结果表明:LPG/柴油双燃料发动机的动力性能比原机动力性能有较大幅度提高,经济性能明显改善.LPG/柴油双燃料发动机的排放性能与原机相比:NOx排放量有一定减少;CO排放量和原机接近;HC排放量在低负荷阶段增加较多,而在高负荷阶段接近.

| Abstract: | The systems including an electronic control unit(ECU),liquefied petroleum gas(LPG) supply system and LPG electronic control injection system were developed,by which a 295T DI diesel engine was successfully refitted.Subsequently,taking respectively diesel oil and LPG / diesel as fuel,under the same condition,performance tests of the modified engine were carried out.Results indicated that the refitted engine's power performance increased in a quite big range,economy performance became better,and NOx emission ... |
