Abstract
Provided is a fuel injection device and a control unit therefor which enable reliable ignition even in a case where fuel pressure is low immediately after starting an engine. In the control unit for controlling an injector injecting fuel into an internal combustion engine, a plurality of injectors is provided in the internal combustion engine, a static flow rate of a first injector is configured to be smaller than a static flow rate of a second injector. In a case where a fuel pressure of fuel supplied by a pressurizing unit is lower than a set value set lower than a fuel pressure in warming up, an injection ratio of the first injector is controlled to increase according to a difference between a fuel pressure of fuel from the pressurizing unit and a fuel pressure in warming up.
