| 摘 要： | 本文通过在喷油泵试验台上测定高压油路实际压力波传播速度，论述了在油一汽两相状态下，柴油机喷油系统中高压油管和喷油嘴油道内音速的变化规律，并指出造成高压油路各段音速不同的原因是高压油路内汽泡分布的不均匀性。

| Abstract: | The propagation velocity of pressure Wave in Diesel injection pipe and nozzle holder has been measured on an injection pump test stand.The authors have further studied the regularity of sound velocity under condition of Oil-gas two Phase flow in Diesel fuel injection system and also pointal out that the reason of difference of sound velocity of different section of the oil delivery way of Diesel injection system is the non-homogeneous distribution of cavitation. |
