FUEL INJECTION DEVICE AND CONTROL DEVICE FOR VEHICLE

Japanese Patent JP2017075580

A

PROBLEM TO BE SOLVED: To provide a fuel injection device for a vehicle that can suitably inhibit a temperature of fuel from becoming high.SOLUTION: A fuel injection device 10 includes: a low-pressure pump 12 for discharging fuel in a fuel tank 11; a low-pressure delivery pipe 14 for supplying the fuel discharged from the low-pressure pump 12 to a port injector 15 for injecting the fuel into an intake port 4 of the engine 1; a high-pressure pump 16 for pressurizing and discharging the fuel discharged from the low-pressure pump 12; a high-pressure delivery pipe 18 for supplying the fuel discharged from the high-pressure pump 16 to a cylinder injector 19 for injecting the fuel into a cylinder 5 of the engine 1; and a discharge pipe 20 that is connected between the low-pressure delivery pipe 14 in a low-pressure fuel system from the fuel tank 11 to the intake port 4 and the high-pressure delivery pipe 18, can discharge the fuel in the high-pressure delivery pipe 18 to the low-pressure fuel system, and can increase discharge amount of the high-pressure pump 16.SELECTED DRAWING: Figure 1
