Air intake apparatus of multicylinder internal combustion engine

Abstract

Abstract PURPOSE: To allow a strong disturbance to be generated in a combustion chamber when necessary, securing a high filling efficiency in high speed high load operation by allowing the mixed gas flow which flows in an intake port in low load operation to be deflected and energized. CONSTITUTION: The high speed mixed gas flow which passes through a mixed gas flow passing slit 33 advances along the upper wall surface of an intake port 5b as shown by the arrow A and then passes through a slit formed between an intake valve 3b and the seat of the valve 3b and flows into a combustion chamber 10. On the other hand, a communication branched passage 30b which gushes the mixed gas in suction stroke is directed in the direction of flow of the mixed gas of which stream is delfected along the upper wall surface of an intake port b as shown by the arrow A, so the deflected mixed gas flow is energized by the mixed gas flow which gushes out from the communication branched passage 30b, and thus the mixed gas is allowed to flow into the combustion chamber 10 in a considerably high speed.
