摘　　要：为满足船用柴油机的自动化控制需求,提升其安全性能和经济性能,目前大多数船用低速柴油机都会配置气缸压力监测系统,而该系统的标定和应用常出现问题。由此,对MAN ME-C型柴油机在台架试验过程中出现的标定故障进行分析,结合气缸压力监测系统的结构和工作特性,采用曲线分析工具对系统标定过程中的缸压曲线进行分解,提取关键数据并对便携式压力传感器与在线压力传感器的测量结果进行对比分析,从而判断标定故障发生原因。该研究可供气缸压力监测系统在柴油机上的应用及其标定故障排查参考。Most low-speed marine diesel engines are equipped with cylinder pressure monitoring system as one of the effective safety assurance auto-control systems.The calibration failure of the system application are analyzed by a shop test with the MAN ME-C diesel engine.The cylinder pressure curve acquired from system calibration is studied by the curve analysis tool,key data are analyzed comparatively to target specific cause of calibration failure.The research can be a reference for application of cylinder pressure monitoring system and calibration troubleshooting.
