PROBLEM TO BE SOLVED: To provide a vehicular fuel cooling device capable of quickly lowering a temperature in a fuel tank.SOLUTION: The vehicular fuel cooling device includes a return passage 6 for returning to a fuel tank 5 surplus fuel not injected, as return fuel, of fuel supplied into a fuel injection valve 2, and a fuel cooling part 7 provided in the return passage 6. Part of refrigerant for a vehicular air conditioner is circulated through the fuel cooling part 7 to cool the return fuel by heat exchange with the refrigerant flowing through the fuel cooling part 7. In the vehicular fuel cooling device, when part of the refrigerant is circulated through the fuel cooling part 7 to cool the return fuel, the drive amount of a compressor 8 is further increased as compared with the time when the return fuel is not cooled. |
