以研究柴油机缸内雾场测量方法为目的，设计改造了适用于缸内雾场测量的单缸柴油试验机，并研制了激光器和试验机喷油系统同步工作控制系统，成功实现了以曲轴转角为基准的同步拍照．在此基础上，初步实现了缸内雾场的激光全息测量 In order to study the measurement method of diesel engine in-cylinder fog field, a single-cylinder diesel testing machine which is suitable for in-cylinder fog field measurement was designed and rebuilt. The synchronous working control system of laser and test machine fuel injection system was developed. As the base of the synchronous camera. On this basis, the laser holographic measurement of cylinder fog field has been preliminarily realized
