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 7):
A control method of an internal combustion engine, the internal combustion engine including\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, the control method comprising: setting, by the electronic control nit, 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; controlling, by the electronic control unit, 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 setting, by the electronic control unit, 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, 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.
