FUEL INJECTION DEVICE OF INTERNAL COMBUSTION ENGINE AND FUEL INJECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a fuel injection device and a fuel injection method which heat fuel in a fuel injection valve with a heater, and prevent generation of vapor in the fuel injection valve caused by excessive temperature rise of the fuel in the fuel injection valve.SOLUTION: A fuel injection device for heating fuel in a fuel injection valve with a heater prohibits a fuel cut (step S320), when the fuel in the fuel injection valve is heated with the heater (step S310:YES).
