    摘要： A method to operate an electronic controlled internal combustion engine to perform on board NOx emissions level diagnostics. In one embodiment, the method may include operating the engine to maintain a predetermined temperature for a predetermined period of time, determining whether the engine operating status is stable for one of cruise control, idle engine speed, engine torque, or high idle regeneration for a predetermined period of time, cycling the EGR valve between a first position for a predetermined period of time and then in a second position for a predetermined period of time, a determining a change in engine out NOx levels to determine whether an engine component or system is malfunctioning.

    摘要： 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.

    摘要： The present invention relates to a method to protect a starter from over heating during any cranking operation to start an electronically controlled internal combustion engine having an electronic control unit with a memory. The method includes constraining the time during which a cranking operation may proceed and ensuring that the starter temperature is within a predetermined range to ensure that the starter does not operate for a time period that permits the starter to heat up beyond a predetermined temperature range.

    摘要： There is disclosed a method for diagnosing slow EGR response in an internal combustion engine equipped with an electronic controller with memory. In one embodiment, the method includes passing an EGR setpoint value and an actual EGR value through first order filters to eliminate high frequency noise; determining an actual EGR gradient as a function of any difference between the EGR set point and the actual EGR value while simultaneously determining an actual EGR gradient; and logging a fault in the electronic controller if the expected EGR gradient is greater than the actual EGR gradient by a predetermined amount.
