In an internal combustion engine control system for controlling an internal combustion engine, comprising a fuel injection control means for controlling fuel injection quantity to be injected by a fuel supply system for supplying fuel to the internal combustion engine, and fuel injection timing, and a variable valve control means for continuously or gradually varying at least opening timing, closing timing or lift of a intake valve or an exhaust valve for sealing up a combustion chamber of the internal combustion engine, the fuel injection control means controls at least fuel injection quantity or fuel injection timing on the basis of a value of a controlled variable provided by the variable valve control means. Since air quantity can be regulated by a variable valve timing mechanism, pumping loss and fuel consumption can be reduced. Fuel injected into the combustion chamber can be atomized by opening the intake valve so that a shock wave is generated in the combustion chamber and, consequently, stable combustion can be achieved without deteriorating the quality of the exhaust gas. <IMAGE> |
