Abstract
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.
