Abstract: A fuel injection device includes: an injector, an electronic control device, a communication circuit, and a power supply circuit. A memory is provided in the injector for storing fuel injection control data set for each injector. The electronic control device controls a fuel injection of the injector based on the control data. The communication circuit is installed for each injector, and enables the electronic control device to access the memory via wireless communication. The power supply circuit is installed for each injector, has a power source that supplies electric power to the communication circuit, and receives electric power to charge the power source from a drive line that connects the electronic control device and a drive unit of the injector.
