Title:
AIR INTAKE STRUCTURE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/008900
Kind Code:
A1
Abstract:
Provided is an air intake structure for an internal combustion engine, with which it is possible to intensify a tumble vortex and simplify the configuration by introducing intake air to a tumble flow path without the provision of a tumble control valve. Disclosed is an air intake structure for an internal combustion engine, the air intake structure comprising a throttle valve 75 inside a throttle body 7 having an air intake path 70 which constitutes a portion of an air intake flow path 80, the air intake flow path being partitioned into a tumble flow path 80A and a main flow path 80B by a partitioning part 81 downstream from the throttle valve. The throttle valve is a butterfly valve that is rotatably supported inside the throttle body by a throttle valve shaft 76 oriented so as to perpendicularly intersect with the center axis X of the air intake path. A valve body 77 of the throttle valve includes a one-end-side half body 77A and an other-end-side half body 77B by being bisected with the throttle valve shaft therebetween. The cross-sectional area of the main flow path is formed so as to be greater than the cross-sectional area of the tumble flow path.
