摘要：
When a pressure-feeding period of a supply pump and an injection period of an injector overlap and an actual injection quantity is affected by a pump pressure-feeding quantity of fuel supplied by the supply pump, an engine control unit (ECU) calculates the pump pressure-feeding quantity supplied during the injection period and calculates a correction value in accordance with the pump pressure-feeding quantity. The ECU corrects a command injection quantity with the correction value. Thus, even if injection start timing changes in accordance with a change in an operating state and if the pump pressure-feeding quantity supplied during the injection period changes because of the change in the injection start timing, variation in the actual injection quantity can be inhibited. As a result, the injector can inject an optimum quantity of the fuel.
