A diesel engineincludes an injectorthat uses a solenoid to directly drive a needle valve and inject a fuel and an injector control devicethat controls the driving by the injector. The injector control deviceincludes a charge voltage control circuit, a storage unitthat stores a correction value related to an injection amount of the fuel injected from the injector, and an injector control circuitthat controls the driving by the injectoron the basis of each of a voltage supplied from the charge voltage control circuitand the correction value stored in the storage unit. The correction value is set according to a voltage applied to a terminal of the injector control deviceconnected to a load when a current starts to flow in the load connected to the injector control device
