SOLUTION: Engine start request Rst is generated when an ignition start switch is turned on, and a fuel pump is started in accordance with generation of the Rst. A fuel pressure is increased at about the time when an engine speed Ne rises up via a delay time td from generation of the Rst. Accordingly, improvement of an exhaust characteristic when an engine is started and improvement of engine startability can be attained by generating a proper value obtainable in a fuel supply amount from an early period. |
