装置。In a fuel return device, a part of the fuel supplied from a fuel tank to an engine via a supply pipe by a fuel pump is returned to the fuel tank via a return pipe, and a flow path variable valve is provided in the middle of the return pipe. In addition, an engine suction negative pressure detection means and a rotation speed detection means are provided, and the opening degree of the variable flow path valve is determined when the engine is at low speed and under low load, when the suction negative pressure is above a predetermined value and the rotation speed is below a predetermined value. A return fuel control device for an internal combustion engine configured to increase the opening degree and decrease the opening degree under other conditions.
