Abstract
A fuel supply device for an internal combustion engine includes a tank, a fuel injection valve, a fuel passage, a second shut-off valve configured to open and close the fuel passage, a temperature increasing mechanism that increases a temperature of fuel flowing into the second shut-off valve, and a controller that executes a fuel pressure control. In the fuel pressure control, the second shut-off valve is repeatedly opened and closed such that a fuel pressure in a section of the fuel passage connected to the downstream side of the second shut-off valve falls within a range defined by an upper limit value and a lower limit value. The controller operates the temperature increasing mechanism such that the temperature of the fuel flowing into the second shut-off valve is increased during the execution of the fuel pressure control.
