Patent ID: 7845333

Claim:
An internal combustion engine apparatus provided with an internal combustion engine, said internal combustion engine apparatus comprising: a fuel injection device capable of injecting a fuel for each cylinder of said internal combustion engine; an ignition device capable of ignition for each cylinder of said internal combustion engine; a target fuel injection amount setting device that sets, as a target fuel injection amount, a fuel injection amount based on target power to be output from said internal combustion engine and a prescribed fuel restriction when a fuel amount increasing condition for an increase in the amount of a fuel supplied to said internal combustion engine does not hold, and sets, as said target fuel injection amount, a fuel injection amount that is increased by use of the degree of an amount increase based on a prescribed amount increase restriction with respect to a fuel injection amount based on said target power and said prescribed fuel restriction when said fuel amount increasing condition has held; a fuel injection control device that controls said fuel injection device so that fuel injection is performed on the basis of said set target fuel injection amount; a target ignition timing setting device that sets, as target ignition timing, timing based on a prescribed ignition restriction when a rapid-change condition, under which the operating state of said internal combustion engine comes to a prescribed rapid-change state, does not hold, and sets a delay angle amount within a range of a limit to said delay angle amount that is set to ensure that said delay angle amount decreases in proportion as the degree of an amount increase based on said prescribed amount increase restriction, and sets, as said target ignition timing, timing on the delay angle side by the set delay angle amount compared to the timing based on said prescribed ignition restriction when said rapid-change condition has held; and an ignition control device that controls said ignition device so that ignition is performed with said set target ignition timing.
