介绍了针对P -T燃油系柴油机的特点设计的一套便携式故障诊断系统。采用非接触定位信号 ,解决了无高压油管柴油机无法用提取高压脉冲传感信号来确定缸位的问题。对发动机的一系列参数进行了综合测试 ,并参照厂家的技术要求对发动机的故障进行诊断 ,为柴油机的维修与管理提供了依据。实际应用表明 ,该系统在起动电流法测缸漏方面简便有效。
A portable fault diagnosis system designed for P-T diesel engine is introduced. The non-contact positioning signal solves the problem that no high-pressure tubing diesel engine can not determine the cylinder position by extracting the high-pressure pulse sensing signal. A series of parameters of the engine were tested comprehensively and the failure of the engine was diagnosed with reference to the technical requirements of the manufacturer, which provided the basis for the maintenance and management of the diesel engine. Practical application shows that the system is simple and effective in start-up current method for measuring cylinder leakage.
