Abstract
A fuel injection apparatus including a controller to output an injection time command signal and an opening movement time command signal to command an opening movement time from a closed state to an open state of an electromagnetic fuel injection valve and a control circuit, coupled to the controller, to change an electric current flowing in a coil of the electromagnetic fuel injection valve between when the electromagnetic fuel injection valve is closed and opened. The controller sends both the injection time command signal and the opening movement time command signal through the same signal line to the control circuit.
