Abstract:
An air intake controller for an internal combustion engine having an air intake passage and an injector for injecting fuel, wherein stratified charge combustion of mixture of the air and the fuel is executed within a combustion chamber, the controller comprising:condition detecting means for detecting operating conditions of the engine;a swirl control valve for selectively opening and closing the air intake passage to swirl the mixture within the combustion chamber when executing the stratified charge combustion;an actuator for driving the swirl control valve;computing means for computing a target opening angle of the swirl control valve in response to detected operating conditions;swirl control means for controlling the force of the swirl by controlling the actuator in response to the computed target opening angle;fluctuation detecting means for detecting fluctuation of the engine rotation; andcorrecting means for correcting the target opening angle in response to the detected fluctuation of the engine rotation.
