Abstract
An air intake side secondary air supply system for an internal combustion engine is provided with a linear type solenoid valve disposed in an air intake side secondary air supply passage leading to an intake air passage, downstream from the throttle valve. The opening degree of the linear type solenoid valve is controlled continuously by a drive current supplied to the solenoid. The magnitude of the drive current of the solenoid is determined by providing a base value of current which is responsive to a plurality of engine parameters that represent the engine load, and by correcting the base value in accordance with a result of the sensing of concentration of an exhaust gas component.
