Abstract:
When a pressure of fuel is intensified using a pressure intensifier an electronic control unit is configured to set a target common rail pressure to be higher as a fuel leakage volume that is a volume of fuel leaking from a common rail to a fuel tank becomes larger until a three-way valve is switched from a state in which the pressure intensifier is connected to the common rail to a state in which the pressure intensifier is connected to the fuel tank.

Claim (Index 6):
An internal combustion engine comprising:\n a fuel tank; a supply pump configured to increase a pressure of fuel that is supplied from the fuel tank; a high-pressure fuel passage configured to allow the fuel of which the pressure has been increased by the supply pump to flow; a pressure intensifier configured to intensify the pressure of fuel supplied from the high-pressure fuel passage; a low-pressure fuel passage configured to allow fuel, that is not intensified by the pressure intensifier and returned to the fuel tank, to flow in order to drive the pressure intensifier; a switching device disposed in the pressure intensifier and configured to switch a state in which the pressure intensifier is connected to the high-pressure fuel passage to a state in which the pressure intensifier is connected to the fuel tank in order to intensify fuel; a fuel injector configured to inject fuel of which the pressure has been intensified by the pressure intensifier; and an electronic control unit,\n the electronic control unit configured to set a target fuel pressure that is a target value of the pressure of fuel supplied to the high-pressure fuel passage based on a target injection pressure that is a target value of the pressure of fuel supplied to the fuel injector, the electronic control unit configured to control the supply pump such that the pressure of fuel in the high-pressure fuel passage reaches the target fuel pressure and then to drive the pressure intensifier, and the electronic control unit is configured to set the target fuel pressure to be higher as a fuel leakage volume becomes larger during a predetermined period of time when the pressure of fuel is intensified by the pressure intensifier, \n the predetermined period of time being a period of time until the switching device switches the state in which the pressure intensifier is connected to the high-pressure fuel passage to the state in which the pressure intensifier is connected to the fuel tank, and the fuel leakage volume being a volume of fuel that leaks from the high-pressure fuel passage to the fuel tank via the switching device.
