ABSTRACT:
A fuel vapor purging control system for an internal combustion engine is provided. This purging control system incorporates an air/fuel ratio compensating system which includes a purge control valve for controlling a purge flow rate of an air-fuel vapor mixture flowing into an induction system of the engine through a purge passage according to a preselected engine operating condition parameter, a sensor disposed in the purge passage for determining an amount of fuel in the air-fuel vapor mixture, an air/fuel ratio controller for modifying an amount of fuel in an air/fuel mixture injected through a fuel injection system of the engine based on the amount of fuel in the air-fuel vapor mixture determined by the sensor for assuring a desired air/fuel ratio of the air/fuel mixture entering a combustion chamber of the engine.
