摘　　要：利用激光全息技术对电控多点汽油喷嘴的喷雾特性进行了研究。介绍了用于汽油喷雾场研究的双脉冲激光全息摄影装置以及喷油和触发的控制系统，使用该系统研究了GM和BOSCH公司生产的两种不同型号喷嘴的喷雾特性，同时发现了漂流、滴油及断续喷射等不正常喷射。实验表明，该系统能有效地评定电控喷嘴的微观性能，为电控汽油喷射发动机改善性能提供依据。The atomizing characteristics of gasoline injector with use of the double-pulsed in-line Fraunhofer holography system have been studied. This paper presents the holography system and the control system of fuel injection. These systems have been used to examine and analyze both GM and Bosch injectors. The abnormal phenomena such as drifting, dripping, and unconlinuous injection can also be found.This system is proved experimentally to be very useful for evaluating microscopic qualities of fuel atomization which affect engine performance.
