HIGH PRESSURE FUEL INJECTION DEVICE

PROBLEM TO BE SOLVED: To high-precisely control a fuel injection quantity even when a fuel pressure is changed. SOLUTION: A fundamental injection time Tr determined according to a target fuel injection quantity has an injection factor corrected by an injection factor correction part 53 by means of a correction factor γ based on an actual pressure value Pa being a measuring result by a fuel pressure measuring part 4. An injection delay is corrected by an opening closing time correction part 54 by means of a correction value δ to obtain an actual injection time Ta. By controlling the opening time of an injector 3A according to actual injection time data DTa, fuel is injected according to a given target injection quantity through control of the opening time of an injector 3A.
