ABSTRACT:
A fuel pressure detector and a pressure accumulator are disposed in a fuel distribution line, an engine control apparatus controlling activation of a fuel pump based on output from the fuel pressure detector. The fuel pump is activated at maximum capacity to fill the fuel distribution line with fuel at a controlled pressure controlled by a fuel pressure regulator, then stopped. In this state, fuel accumulated under pressure in the pressure accumulator replenishes the fuel distribution line until fuel pressure inside the fuel distribution line drops to a predetermined value due to fuel injection by fuel injection valves.
