Abstract
A control system for a multi-cylinder internal combustion engine is provided. The engine is of the kind in which switching between a full cylinder operation with all cylinders in operation and a part cylinder operation with some of cylinders kept out of operation is selectively performed. The control system comprises a first calculator for calculating, at the part cylinder operation, a target intake air fuel quantity per one operative cylinder that enables the engine to produce a torque equal to that at the full cylinder operation, a second calculator for calculating a throttle valve target opening area at the part cylinder operation from the target intake air quantity per one operative cylinder, and a controller for controlling a throttle valve opening degree so that the throttle valve target opening area is obtained. A control method is also provided.
