Abstract

A port injection valve (16) injects fuel to an intake passage (12). In multiple injection processing, a demanded injection quantity (Qd) of the fuel is divided into a synchronous injection quantity (Qs) and a non-synchronous injection quantity (Qns) in accordance with at least one of: the load (Qd), which is a physical quantity having a correlation with the amount of air (NE, Ga) to be filled; and the temperature (THW) of an internal-combustion engine (10). 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 (18). In the intake non-synchronous injection, the fuel is injected at a timing more advanced than in the intake synchronous injection.
