    摘要: An object of the present invention is to provide a control device of an injector capable of suppressing the influence of pressure reduction boiling even if pressure in a combustion chamber is low. In a case where the temperature of fuel injected from a fuel injection valve is within a set high temperature region and the pressure of the combustion chamber is within a set low pressure region, the control device of an in-cylinder direct injection-type injector according to the present invention controls to increase a lift amount of the injector as compared to the case of a low temperature region or a high pressure region.

    摘要: 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.

    摘要: Provided is a fuel injector that is capable of reducing penetration. The fuel injector of the present invention includes a valve body having a valve body side seat surface, a valve seat side seat surface that abuts on the valve body side seat surface, and an injection hole that is provided downstream of a position at which the valve body side seat surface abuts on the valve seat side seat surface. The valve body has a projection that is formed from the valve body side seat surface toward the injection hole, and the projection is formed to be smaller in a direction of fuel flow between seats than a radius of an upstream opening surface of the injection hole.
