ABSTRACT:
When engine rotation speed is increasing in a compression stroke injection mode, a control device determines that a crank angle at injection end timing of an injector deviates toward a delayed crank angle side and performs additional ignition at timing when (or immediately before or after) a crank angle at actual injection end timing of the injector of a present injection cylinder is reached. Thus, even when the crank angle at the injection end timing deviates toward the delayed crank angle side with respect to preset original ignition timing, a combustion state can be stabilized by performing the additional ignition at timing, at which a suitable stratified mixture gas is formed in a cylinder, through the execution of the additional ignition at the timing substantially the same as the actual injection end timing.
