ABSTRACT:
The torque reduction of an internal combustion engine in response to an excessive acceleration spin condition is provided by a combination of disabling selected engine cylinders and spark retard. When a reduction of engine torque output is required in response to an excessive acceleration spin condition of the vehicle, the first level of torque reduction is provided at a level less than the torque reduction resulting from disabling a single cylinder of the engine by retarding the spark timing of the spark ignition in the cylinders. The amount of the retard of spark timing is such that the resulting torque reduction is less than the torque reduction resulting from disabling a single cylinder of the engine.
