引言按照用仪器装备一台作研究用的内燃机车的计划,决定对现有数字式监控装置通常不能记录到的参数进行测取研究。因为柴油机的问题,由喷油系统故障所直接或间接引起的比其他任一系统和装置故障所引起的要多,所以决定通过研究具有下述特点的方法以获得尽可能完整的喷油压力—时间曲线: 1.极其精确地遵循动压力图形的能力,并可与高级压电传感器媲美; INTRODUCTION According to the plan of equipping a diesel locomotive used for research, it is decided to study the parameters that can not normally be recorded by the existing digital monitoring devices. Because of the diesel engine problems caused more or less by the fuel injection system faults than any other system and installation failure, it was decided to obtain the best possible injection pressure by studying a method with the following characteristics - Time curve: 1. The ability to follow dynamic pressure graphs with extreme precision, comparable to advanced piezoelectric sensors;
