Abstract

Provided are an internal combustion engine control device and control method in which a multi-injection process comprises performing an intake synchronized injection and an intake asynchronous injection to inject a required injection amount (Qd) of fuel by operating a port injection valve (16) for injecting fuel into an intake passageway (12). A variable process includes variably setting an injection timing (Is) for the intake synchronized injection on the basis of at least two of three parameters. The injection timing for the intake synchronized injection is expressed by the rotation angle of a crank shaft (28) of an internal combustion engine (10). The three parameters include a rotational speed (NE) of the crank shaft of the internal combustion engine, a valve-opening start timing (DIN, AEs) of an intake valve (18), and a temperature (THW) of an intake system of the internal combustion engine (10).
