Abstract
A fuel injection control apparatus for an internal combustion engine having cylinders each of which includes a fuel injection valve and an intake valve, includes an intake valve controller, a parameter acquiring device, and an injection quantity correcting device. The intake valve controller performs an effective-compression-ratio reducing operation. The parameter acquiring device acquires a correction parameter including at least one of a rotational speed of the internal combustion engine, the valve closing timing of the intake valve, and an intake parameter indicating an intake fresh air amount flowing into the cylinders through an intake system. The injection quantity correcting device corrects a fuel injection quantity for the fuel injection valve in accordance with the acquired correction parameter to suppress variations among air/fuel ratios of air fuel mixtures in the cylinders while the intake valve controller performs the effective-compression-ratio reducing operation.
