  • Soot monitoring method and alert system
    Patent number: 9765673
    Abstract: 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.
    Type: Grant

    Date of Patent: September 19, 2017
    Assignee: Johnson Matthey PLC
