MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202517084511 A) filed by Honda Motor Co. Ltd., Tokyo, on Sept. 5, for 'air intake structure for internal combustion engine.'
Inventor(s) include Kawatsu, Hirotaka.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "According to the present invention, an air intake structure for an internal combustion engine is such that a main passage and a sub passage are formed by a partitioning part that vertically partitions an air intake passage along a passage direction, and intake air is guided to the sub passage, or to the main passage and the sub passage, in accordance with an operating state of the internal combustion engine. In a top view of a combustion chamber, an opening Wa is formed on the basis of a positional relationship in which a center line of the opening is eccentric, in relation to a center line of an outer shape width of the sub passage, by an offset amount set in a direction intersecting the passage direction.. In a side view of the combustion chamber in a state in which an air intake valve is open, an inlet zone is formed on the basis of a positional relationship in which an axial line of the sub passage in the inlet zone is inclined by a relative angle set with respect to a shaft part of the air intake valve. A virtual substantially columnar region in which the cross-sectional shape of the opening of the sub passage is extended in a direction extending toward the inside of the combustion chamber is formed so as not to contact a valve seat edge of the air intake valve in a side view of the combustion chamber in which the air intake valve is opened."
The patent application was internationally filed on Mar. 31, 2023, under International application No.PCT/JP2023/013593.
