  "textContent": "A port injection valve injects fuel into an intake passage. An intake synchronous injection is to inject fuel in synchronization with an opening period of an intake valve. A single injection process is to execute only an intake air non-synchronous injection. A majority of a fuel injection period of the single injection process is prior to the opening timing of the intake valve. A controller causes, when switching a fuel injection process from the single injection process to a multiple injection process, an injection start timing of the intake air non-synchronous injection to be more advanced than an injection start timing of the single injection process prior to the switching.",
