。 A heating means for heating the fuel in the fuel supply path connecting the fuel pump and the injection nozzle, a temperature detection means for detecting the temperature of the fuel fed from the fuel tank to the fuel pump, and a heating means for heating the fuel in the fuel supply path connecting the fuel pump and the injection nozzle. A bypass passage is provided at the junction between the fuel return passage and the bypass passage, which connects the fuel supply passage that leads the fuel from the injection nozzle to the fuel return passage that returns the fuel from the injection nozzle to the fuel tank. When the fuel temperature of the pump is below the set temperature, the amount of fuel returned to the bypass passage side is increased compared to the amount of fuel returned to the fuel tank, and when the fuel temperature of the fuel pump exceeds the set temperature, the amount of fuel supplied is returned to the bypass passage side. A fuel heating device for an internal combustion engine, comprising a flow rate adjusting means for increasing the amount of fuel returned to the fuel tank side compared to the amount of fuel.
