Title: VEHICLE FUEL INJECTION DEVICE AND CONTROL DEVICE
Abstract:
A fuel injection device (10) having: a low-pressure pump (12) that discharges fuel from a fuel tank (11); a low-pressure delivery pipe (14) that supplies the fuel discharged from the low-pressure pump (12) to port injectors (15) that inject fuel into intake ports (4) of an engine (1); a high-pressure pump (16) that pressurizes and discharges the fuel discharged from the low-pressure pump (12); a high-pressure delivery pipe (18) that supplies the fuel discharged from the high-pressure pump (16) to cylinder injectors (19) that inject fuel into cylinders (5) of the engine (1); and a discharge pipe (20) that is connected between the high-pressure delivery pipe (18) and the low-pressure delivery pipe (14) of the low-pressure fuel system from the fuel tank (11) to the intake ports (4), and is configured so as to be capable of discharging fuel in the high-pressure delivery pipe (18) to the low-pressure fuel system and of increasing the discharge amount of the high-pressure pump (16).
