Abstract
The invention improves a combustion at a starting time by refining a fuel at a time of starting the engine so as to minimize an amount of the fuel attached to a wall surface and appropriately form an air-fuel mixture. When the engine starts, a control apparatus executes a control of increasing a fuel pressure supplied to a fuel injector in comparison with a normal operating time just after the engine start, and a divisional injection control of divisionally injecting the fuel injection for one cycle of the engine by the fuel injector at a plurality of times.
