    摘要： A vehicle engine utilizes adaptive knock retard in which non-volatile memory cells store slowly changed values based on sensed knock to retard ignition timing. Upon engine start, the values in one or more of the memory cells may be reduced in a proportional manner to provide a more advanced engine ignition timing more appropriate to engine warmup. The proportional reduction is based on the sensed engine coolant temperature at the initiation of engine operation, either by itself or through the difference between it and the stored engine coolant temperature from just before the cessation of the last period of engine operation.

    摘要： A method is directed to controlling idle speed for an internal combustion engine. The method provides for monitoring a plurality of vehicle system signal inputs, determining a baseline load control signal based on the vehicle system signal inputs, determining a maximum load control signal based on the vehicle system signal inputs, determining an anticipated load control signal based on the vehicle system signal inputs, determining an idle speed control signal based on the baseline control signal and the anticipated control signal, modifying the idle speed control signal based on vehicle system signal inputs, and controlling the idle speed based on the modified idle speed control signal.
