PROBLEM TO BE SOLVED: To more properly predict early ignition, and to more properly perform fuel injection in an intake stroke for suppressing generation of the early ignition.SOLUTION: A fuel injection controller of an internal combustion engine for controlling a fuel injection valve 15 arranged in a gas introduction passage to a cylinder positioned at an upstream side with respect to an intake valve provided on the cylinder of the internal combustion engine has: a fuel injection valve control part 60 for injecting fuel from the fuel injection valve 15 in an exhaust stroke of the cylinder in which an exhaust valve is open; a cylinder internal gas temperature calculating part 58 for estimating a cylinder internal temperature when the cylinder is compressed; and an injection control detail determination part 59 for injecting the fuel from the fuel injection valve 15 in the cylinder intake stroke in which an intake valve is open when it is determined that the cylinder internal temperature in compression calculated by the cylinder internal gas temperature calculating part 58 is higher than a temperature predicted to generate the early ignition, and changing control to be performed by the fuel injection valve control part 60 so as to supply the fuel into the cylinder. |
