を特徴とする内燃機関の偏流バルブ構造。 A valve body supported in a holding hole facing the confluence of a first intake port and a second intake port connected to the combustion chamber of the internal combustion engine allows the second intake port to freely open and close, and also opens and closes the second intake port. In the biased flow valve structure, the valve body is composed of a main valve and a sub-valve, the holding hole is in contact with the confluence part, and is formed to have a diameter larger than the second intake port diameter, and The sub-valve is characterized by having a sub-valve that selectively abuts between the stopper facing the second intake port, contacts the main valve at its base, is biased toward the opening side, and is connected to the main valve. A biased flow valve structure for an internal combustion engine.
