FUEL INJECTION CONTROL DEVICE AND FUEL INJECTION CONTROL METHOD FOR INTERNAL COMBUSTION ENGINE

A control device for an engine (10) includes an ECU (31) configured to: control an actual pressure supplied to an injector (27) to a target pressure; calculate a required energization time required for a fuel injection quantity; set an energization time for each injection accordlingly; execute a switching processing for switching a manner in which the energization time is set when the required energization time is shorter than a full lift minimum energization time, which a time following the needle-bouncing, which is due to the injector's valve body (45) reaching full opening, causing a low accuracy of the injection quantity control; set as a set value of the energization time through the switching processing: the required energization time when a deviation between actual and target pressure is equal to or larger than a predetermined value or the predetermined time when the deviation is less than the predetermined value.
