PROBLEM TO BE SOLVED: To provide a fuel supply device for internal combustion engine, capable of improving low-temperature startability in an internal combustion engine using fuel containing biofuel.SOLUTION: The device includes a diesel engine 10 using a mixed fuel containing biofuel; a fuel tank 16 for storing the mixed fuel; a second filter 36 provided in a second suction pipe 34 communicating with the fuel tank 16; and a second fuel pump 32 for introducing the mixed fuel in the fuel tank 16 to the second filter 36. A cooler 38 for cooling the mixed fuel introduced to the filter is provided around the second filter 36. Preferably, the device further includes a second fuel tank 44 for storing low-concentration biofuel passed through the second filter 36, and the low-concentration biofuel stored in the second fuel tank 44 is used in low-temperature starting of the diesel engine 10. |
