  • System for controlling output of an automotive engine
    Patent number: 5459662
    Abstract: A first desired engine torque is obtained based on engine speed at slipping of drive wheels of a vehicle. In accordance with the engine speed, and the first desired engine torque, a second desired engine torque is calculated. In response to actual engine torque of an engine and the second desired engine torque, an engine torque reducing quantity is obtained. The number of cylinders supplied with fuel is reduced in accordance with the engine torque reducing quantity, thereby reducing the engine torque of the engine.
