ABSTRACT:
An ECU executes a program including the steps of: calculating a base timing of injection (INJB); determining whether an engine knocks; if the engine knocks, increasing a correction value INJK(I) applied to correct a timing of injection; and calculating the base timing of injection INJB plus the correction value INJK(I) to obtain a timing of injection INJ.
