  "textContent": "A port injection valve injects fuel into an intake passage. A base injection amount is an injection amount proportional to an amount of fresh air introduced into a cylinder of an internal combustion engine. A division process involves dividing the base injection amount into a synchronous injection amount and an asynchronous injection amount. In an intake-synchronous injection, the fuel is injected in synchronization with a period in which an intake valve is open. In an intake-asynchronous injection, the fuel is injected at a time advanced with respect to the intake-synchronous injection. In a selective correction process, the asynchronous injection amount is corrected according to a required correction amount for the base injection amount, and the synchronous injection amount is not corrected.",
