Abstract
A fuel injection control device for an internal combustion engine, includes a fuel pressure sensor and circuitry. The fuel pressure sensor detects an actual fuel pressure of the fuel supplied to a cylinder fuel injection valve. The circuitry calculates a demanded amount of the fuel supplied to the internal combustion engine. The circuitry calculates a cylinder injection amount of fuel injected from the cylinder fuel injection valve. The circuitry corrects the cylinder injection amount to decrease in accordance with a degree of drop in the actual fuel pressure comparing to a target fuel pressure of the fuel supplied to the cylinder fuel injection valve such that fuel injection from the cylinder fuel injection valve ends by a target injection end timing. The circuitry calculates a port injection amount of the fuel injected from a port fuel injection valve based on the demanded fuel amount and the corrected cylinder injection amount.
