    摘要: A vehicle controller adjusts fuel delivered to an engine to compensate for an unknown fuel type being added to a fuel tank in a flexible fueled vehicle. The controller fuels a first set of engine cylinders according to first fueling scheme. For example, the controller fuels the first set assuming that E85 fuel was added to the fuel tank. The controller fuels a second set of engine cylinders according to a second fueling scheme. For example, the controller fuels the second set assuming that E0 fuel was added to the fuel tank. The controller continues to fuel the engine in this manner until an oxygen sensor becomes available. When the oxygen sensor becomes available, the vehicle controller may fuel the engine according to information from the oxygen sensor.

    摘要: A method for controlling a clutch for an air conditioner compressor having an armature and a rotor separated by an air gap width powered by an internal combustion engine having a crankshaft includes the steps of receiving a signal to engage the clutch, moving the armature to the rotor over a predetermined time to reduce the air gap width to zero, measuring rotational acceleration of the crankshaft of the internal combustion engine, and changing the predetermined time to reduce the air gap width to zero such that subsequent movement of the armature reduces the changes in the rotational acceleration of the crankshaft.

    摘要: A spark control method for a vehicle engine is provided for enhancing engine performance and fuel economy prior to a fully warm state. The spark control method is based on coolant temperature and engine speed while accounting for an engine position and time from the start-to-run transfer. More particularly, the methodology of the present invention initially determines if the desired spark advance is before top dead center and if the throttle is open. If so, the methodology loads engine speed and coolant temperature to the engine control unit and interpolates a spark advance multiplier value. Thereafter, the current engine position pulse is loaded and an engine position pulse multiplier is interpolated and applied to the spark advance multiplier value. Next, the time since the start-to-run transfer is loaded and a time since start-to-run transfer multiplier is interpolated and applied to the spark advance multiplier value. Finally, the spark is advanced via the spark advance multiplier value, as adjusted by the engine position pulse multiplier and the time since start-to-run transfer multiplier. Upon engine operation reaching an after top dead center condition or when the throttle is closed, the methodology of the present invention is exited and engine operation is returned to normal spark control.

    摘要: The present invention provides an apparatus for limiting the occurrence of knock conditions in an internal combustion engine. The apparatus includes a throttle sensor that detects transition of an engine throttle from a steady state throttle condition to a wide open throttle condition. Further, spark means is provided for generating a spark for an engine cylinder firing event, with the spark means generating the spark with an associated spark advance. Further, a controller is provided that is responsive to the wide open throttle condition detected by the throttle sensor and that causes the spark advance to incrementally advance to a maximum level over a predetermined time period, thereby minimizing the occurrence of engine knock conditions.
