PROBLEM TO BE SOLVED: To prevent the occurrence of problems caused by the injection of excessive fuel in an early period of fuel injection when an accelerator is stepped for re-accelerating during decelerating the engine in a common rail-type fuel injection system. SOLUTION: When the accelerator is stepped for re-accelerating during decelerating the engine, the target common rail pressure PS and the actual common rail pressure P at that time are compared, a correction valueαin an injection starting period is determined on the basis of the deviationΔP, and an actual injection starting period A is delayed by the mount of the correction valueαto a target injection starting period AS to make the actual injection amount be approximately agreed with the target injection amount.
