Abstract
A control system for a variable displacement engine for an automobile changes a number of the cylinders of the engine when an engine load changes. The system sets an amendment value to a throttle valve opening in accordance with a throttle valve opening and an engine revolution. The system controls the throttle valve before the system changes a number of the cylinders. Thus the throttle valve is controlled to obtain the same torque before and after the change of the number of the cylinders.
