    摘要： A system and method for determining EGR flow in a multi-cylinder internal combustion engine include determining specific heat of the exhaust gas based on current engine operating conditions and determining EGR flow rate based on the determined specific heat and a signal provided by a sensor. In one embodiment, a species tracking model is used to determine the amount of various species within the exhaust gas which may include oxygen, nitrogen, carbon dioxide, and water, for example, to determine the current specific heat, which is compared to a reference specific heat for the sensor, the difference being used to adjust the sensor value and determine the EGR mass flow rate. The species tracking model uses a simplified combustion model to estimate the amount of each specie in the exhaust gas based on various engine operating parameters, such as fuel, air/fuel ratio, and turbo boost, for example.

    摘要： A method for determining a coefficient gain to a signal command to actuate an air intake throttle plate to ensure that the throttle plate responds in a desired manner within a desired responsiveness with relative conformity over the life of the air intake manifold with out losses due to variability in spring/motor/friction responsiveness in the throttle plate actuator. The coefficient gain is multiplied to successive throttle plate command signals to ensure the throttle plate responds as desired. The coefficient gain is re-determined periodically when it is determined that the throttle plate responsiveness does not meet desired throttle plate responsiveness.

    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.
