The present invention relates to a control device for an internal combustion engine including a port injection valve that injects fuel into an intake port and an in-cylinder injection valve that injects fuel into a cylinder. The control device comprises an electronic control unit; an electronic control unit controls the port injection valve and the in-cylinder injection valve such that a port increment correction value and an in-cylinder increment correction value differ when a fuel cut is recovered; the port increment correction is a fuel increment correction that decreases with the elapse of time at the time of port injection; the in-cylinder increment correction is a fuel increment correction that decreases as time elapses at the time of in-cylinder injection. 本发明涉及包括向进气口喷射燃料的端口喷射阀和向缸内喷射燃料的缸内喷射阀的内燃机的控制装置。所述控制装置包括电子控制单元，该电子控制单元在从燃料切断恢复时，以使端口增量修正的值与缸内增量修正的值不同的方式控制所述端口喷射阀及所述缸内喷射阀，所述端口增量修正是在端口喷射时伴随于时间的经过而减小的燃料增量修正，所述缸内增量修正是在缸内喷射时伴随于时间的经过而减小的燃料增量修正。
