Abstract: A port injection valve injects fuel into an intake passage. A controller increases a base injection amount over a predetermined period after the internal combustion engine is started and gradually decreases an increase correction ratio of the base injection amount. One of two processes, a multiple injection process and a single injection process, is selected in order to inject the increased base injection amount of fuel. The increase correction ratio is set to be a smaller value in the multiple injection process than in the single injection process.
