Control device for internal combustion engine

摘要

A control device for an internal combustion engine including fuel injection valves which are disposed at an air intake port for the internal combustion engine and inject fuel from the air intake port toward respective cylinders for the internal combustion engine; and an air flow velocity accelerating means which accelerates air flow velocity in the air intake port, wherein the fuel injection time from the fuel injection valves is controlled in synchronism with and during an air intake stroke for the internal combustion engine as well as respective injection ports of the fuel injection valves are positioned at or near an accelerated air flow portion formed by the air flow velocity accelerating means. Thereby, in a multi point fuel injection system quality and spatial formation of air fuel mixture in the respective cylinders is enhanced and transportation time delay due to atomization of injected fuel droplet diameter is eliminated.
