Claim 4:
5. The controller according to claim 4, wherein
the processing circuitry is configured to set the second injection amount of water to a maximum injection amount of water in the second setting process when the pressure of the gas in the crank chamber is greater than or equal to the second specified value, the maximum injection amount of water being a maximum value of an amount of water in the target injection amount of water capable of being injected from the water injection valve when the intake valve is closed, and
the processing circuitry is configured to:
when the pressure of the gas in the crank chamber is greater than or equal to the first specified value and less than the second specified value,
set the second injection amount of water to be smaller than the maximum injection amount of water in the second setting process; and
set the first injection amount of water to be smaller as a difference between the first specified value and the pressure of the gas in the crank chamber becomes larger in the first setting process.
