摘　　要：柴油机结构复杂,振源众多,常规的振动分析及单项指标测试对于故障的定位与诊断 精确度不高。针对这种状况,开发了柴油机多参数监测与诊断系统。该系统由传感器、诊断仪主 机和便携式电脑组成。通过采集振动、压力、温度、转速和功率等信号,建立故障模式库,对各 类故障综合值的评定,能够诊断出柴油机的常规故障。喷油器堵塞故障诊断的实例表明,新开发 的柴油机多参数监测与诊断系统具有较高的有效性和实用性。The diesel engine is a complicated machine with many vibration sources,so the traditional vibration analysis and single parameter test method cannot determine the diagnosis accurately.Thereby a multiparameter monitoring and diagnosis system for diesel engines is developed.The system is comprised of sensors,a data-collecting instrument and a portable computer.By collecting and analyzing the vibration, pressure,temperature,rotating speed,power and etc.,and establishing the fault mode library and evaluating the characteristics parameters as a whole,the system can diagnosis the often.occurred faults.The diagnosis of nozzle jam indicates thatthe systemisvalidandpracticable.
