Abstract
A fuel supply amount control system for an internal combustion engine having exhaust gas recirculation passage extending between the exhaust passage and the intake passage, and an exhaust gas recirculation valve arranged across the exhaust gas recirculation passage, for recirculating part of exhaust gases emitted from the engine to the intake passage, has an ECU which detects an actual valve lift amount of the exhaust gas recirculation valve, determines a desired valve lift amount of the exhaust gas recirculation valve, based on operating conditions of the engine, and controls the exhaust gas recirculation valve, based on determined the desired valve lift amount and the detected actual valve lift amount, when the engine is in a predetermined operating region where conditions for executing exhaust gas recirculation control are satisfied. A basic fuel supply amount is calculated based on operating conditions of the engine, and a correction coefficient for correcting the basic fuel supply amount, is set based on the actual valve lift amount and the desired valve lift amount, when the engine is in the predetermined operating region. The basic fuel amount is corrected based on the correction coefficient.
