Abstract

Engine control apparatus includes, but is not limited to a determining device for determining whether or not the engine is operated under predetermined deceleration operating conditions or predetermined acceleration operating conditions and for individually deactivating two or more cylinders in a disenabling sequence which is different from the firing sequence if the engine is operated under predetermined deceleration operating conditions, and/or for individually reactivating two or more of the cylinders in a reactivating sequence which is different from the firing sequence if the engine is operated under predetermined acceleration conditions.
