Claim 3:
4. A control method for an internal combustion engine, the internal combustion engine including:
a cylinder;
an intake passage connected to the cylinder;
a water injection valve configured to inject water into the intake passage; and
an intake valve configured to selectively open and close a connection port between the intake passage and the cylinder,
wherein the control method comprises:
executing a first injection process that causes the water injection valve to inject water when the intake valve is open;
executing a second injection process that causes the water injection valve to inject water when the intake valve is closed; and
setting pressure of the water supplied to the water injection valve to be higher in the second injection process than in the first injection process.
