Abstract
A port injection valve injects fuel to an intake passage. In multiple injection processing, a demanded injection quantity of the fuel is divided into a synchronous injection quantity and a non-synchronous injection quantity in accordance with at least one of: the load, which is a physical quantity having a correlation with the amount of air to be filled; and the temperature of an internal-combustion engine. The fuel is injected through intake non-synchronous injection and intake synchronous injection in this order. In the intake synchronous injection, the fuel is injected synchronously with a valve-open period of an intake valve. In the intake non-synchronous injection, the fuel is injected at a timing more advanced than in the intake synchronous injection.
