ABSTRACT:
A combustion chamber in each cylinder has a plurality of intake valves and intake air is distributed into respective divided flow intake air path portions to enter each combustion chamber from a plurality of the intake valves through these divided flow intake air path portions. And in a fuel injector, injected fuel collides with injected air to promote atomization of injected fuel. Each fuel injector has a plurality of fuel injection ports directed to the respective divided flow intake air path portions and a plurality of air-fuel injection ports which are provided coaxially with the respective fuel injection ports and through which injected fuel passes after colliding with injected air. As a result the injected fuel is smoothly distributed to the respective divided flow intake air path portions.
