一种检测天然气发动机温控系统故障的方法

A Method and System for Detecting Temperature Control System Fault of Natural Gas Engine

天然气发动机是利用发动机循环水汽化和加热天然气提供动力的装置。在温控系统正常的情况下,当发动机运行超过一定时间或发动机水温超过一定限值后,天然气温度会随之上升。因此,可以利用天然气温度与发动机水温的关系来检测温控系统是否存在异常,以达到故障诊断目的。

Natural gas engine is the use of circulating water for natural gas vaporizing and heating,the temperature control system under normal circumstances,when the engine is running over a certain time,the engine water temperature exceeds a certain limit,the gas temperature will rise,based on the gas temperature and engine water temperature to detect whether there is any abnormal temperature control system,the relationship between the purpose of fault diagnosis.
