Patent ID: 8224558

Claim:
An internal combustion engine control apparatus comprising: a fuel supplying portion supplying fuel to the internal combustion engine; an exhaust gas recirculating portion recirculating exhaust gas of the internal combustion engine to an intake side of the internal combustion engine; a flow adjusting portion selectively increasing and decreasing a strength of flow of the supplied fuel and the recirculated exhaust gas in a cylinder of the internal combustion engine; a stop controlling portion controlling the fuel supplying portion to stop the supply of fuel and controlling the exhaust gas recirculating portion to stop the recirculation of exhaust gas, when the internal combustion engine is operated in a predetermined deceleration mode; an in-cylinder flow controlling portion controlling the flow adjusting portion to increase the strength of the flow when the control to stop the supply of fuel is cancelled; and a first residual exhaust gas amount calculating portion calculating a first residual exhaust gas amount which is the amount of the recirculated exhaust gas remaining in the cylinder, when the control to stop the supply of fuel is cancelled, wherein the in-cylinder flow controlling portion controls the flow adjusting portion according to the first residual exhaust gas amount.
