摘要： A system and method of monitoring regeneration of a particulate matter filter for a stationary diesel engine is disclosed. The system monitors exhaust temperature and operating time of an engine to calculate accumulated operating time below a critical temperature. Upon reaching a maximum allowed accumulated operation time, the system initiates a warning signal to inform the operator to increase exhaust temperatures for passive regeneration of the filter. During regeneration, the system periodically measures filter pressure differential and the exhaust temperature to calculate a difference in pressure differentials measured at two different times and determine whether the difference is below a critical value to inform the operator that regeneration is complete.

摘要翻译： 公开了一种用于监测固定式柴油发动机的颗粒物质过滤器的再生的系统和方法。 系统监测发动机的排气温度和运行时间，以计算低于临界温度的累积运行时间。 达到最大允许累计运行时间后，系统启动警告信号，通知操作者增加排气温度，以便过滤器被动再生。 在再生期间，系统周期性地测量过滤器压力差和排气温度，以计算在两个不同时间测量的压力差，并确定差值是否低于临界值，以通知操作者再生完成。
