  • REAL-TIME, TABLE-BASED ESTIMATION OF DIESEL ENGINE EMISSIONS
    Publication number: 20080149081
    Abstract: A real-time, on board, diesel engine emissions estimation with an empirical, table-based approach that accounts for up to eight (8) input parameters, for optimum emissions estimation under steady state or transient engine operation. The method considers a steady state NOx model, steady state Particulate Matter model, transient NOx model and transient Particulate Matter models to populate a table in memory. The switch between steady state and transient models, real time emissions estimations is based on the rate of change of engine speed (RPM). If the rate of change of RPM exceeds a predetermined threshold, transient models for NOx and Particulate Matter are used to operate the engine and reduce emissions of NOx and Particulate Matter.

  • System and method for excluding false back pressure faults after installation of a particulate trap filter
    Patent number: 7374600
    Abstract: A method and system for preventing or minimizing false back pressure faults caused by a new particulate filter in an engine exhaust system. When a new particulate filter is placed in an engine exhaust system, the normal back pressure threshold for the fault detection system is increased by a new filter offset amount. Back pressure faults at the normal level are not recorded for a limited period of engine operation and only records back pressure faults that exceed the normal back pressure threshold by the value of the new filter offset.
