Abstract
An intake control system has intake control valves disposed in intake passages of cylinders of a multi-cylinder internal combustion engine. ECU controls the opening degrees of the intake control valves of the respective cylinders based on signals from sensors to converge rotation speed of the engine in a lower limit rotation speed above which the engine does not stall during an idling operation of the engine.
