摘　　要：在喷油器校验器和喷油泵试验台上对密封座面直径不同的两种油嘴的进行了试验。通过对响声不同油嘴的喷雾照片、针阀运动、嘴端压力、声压信号和柴油机性能试验结果的分析,阐明了喷油嘴在检验时发出不同响声的机理。还指出喷油嘴在喷油器试验台检验时的雾化质量不等同于柴油机工作时的雾化质量,以喷油嘴在检验时发出响声的好坏来判别油嘴好坏的方法是不合适的。Two kinds of nozzles with different sealing diameters are tested on the nozzle tester and pump test bench. Based on the analysis of fuel spay photos, needlelift, pressure of nozzle end,spray noise and diesel engine performance,the mechanism of different spray noise is explained in this paper. The result indicates that the atomization quality of spray that obtained on the nozzle tester is much different from that in running condition,so it is improper to judge the quality of nozzle by the spray noise.
