APPARATUS FOR CONTROLLING INTERNAL COMBUSTION ENGINE

This invention relates to a control device of an engine comprising fuel supply means (21) and air supply means (30), for controlling the air-fuel ratio by controlling supplied fuel and air amounts. In this invention, a learned value (KG) used for setting supplied fuel and air amount correction values is calculated such that a difference (” A/F) of the actual air-fuel ratio relative to a target ratio (A/Fest) becomes small. The supplied fuel and air amount correction values are set by using the learned value. The learned value is calculated immediately before the setting of the supplied fuel or air amount correction value and this correction value is set by using the calculated learned value.
