ABSTRACT:
An ECU estimates a variation amount of fuel which is actually suctioned by a fuel pump based on a fuel pressure in a common rail. Even though the fuel pressure in the common rail deviates from a target fuel pressure, when the estimated variation amount of fuel is substantially zero, an energization quantity to a solenoid of a flow control valve is compulsorily reduced.
