る複吸気弁機関の吸気ポート。 A helical port that spirals around the intake valve and a straight port that extends substantially linearly toward the intake valve are divided by a partition wall that serves as a side wall of the helical port and the straight port, and are opened and closed depending on the load conditions of the engine. In the intake port of a dual intake valve engine in which an intake control valve is provided in the straight port, a first fuel injection valve that injects fuel toward the upstream side is disposed in the helical port,
A second fuel injection valve that injects fuel toward the intake valve downstream of the intake control valve is disposed in the straight port, and a fully open view of the intake control valve and an injection amount occupied by the first fuel injection valve are provided. Increase the proportion of
An intake port of a multiple intake valve engine, characterized in that when the intake control valve is closed, a proportion of the injection amount accounted for by the second fuel injection valve is increased.
