Claim 1:
2. The controller according to claim 1, wherein
the processing circuitry is configured to execute:
a target calculation process that calculates a target injection amount of water based on the running state of the internal combustion engine, the target injection amount of water being a target value of an amount of water to be supplied to the cylinder in the single combustion cycle;
a first setting process that sets the first injection amount of water to a value less than or equal to the target injection amount of water; and
a second setting process that sets the second injection amount of water to a value of a difference between the target injection amount of water and the first injection amount of water, and

the processing circuitry is configured to set the first injection amount of water to a smaller value in the first setting process when the pressure of the gas in the crank chamber is greater than or equal to the specified value than when the pressure of the gas in the crank chamber is less than the specified value.
