Abstract

An internal combustion engine control apparatus including a microprocessor. The microprocessor is configured to perform controlling a fuel injector so as to inject a fuel of a target injection amount by dividing into a plurality of times at a predetermined time interval in an area from a first crank angle at which an intake stroke is started to a second crank angle at which a compression stroke is ended, and setting the predetermined time interval. The microprocessor is configured to perform the setting including setting the predetermined time interval so that a spray length from a tip of the fuel injector to a tip of a spray of the fuel injected from the fuel injector becomes shorter than the spray length when the fuel of the target injection amount is injected at once in the area by a predetermined rate.
