Title:
INTAKE STRUCTURE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2024/070901
Kind Code:
A1
Abstract:
The present disclosure is intended to provide a configuration with which it is possible to promote the generation of vortex flow in a combustion chamber over a wider operating range while minimizing any increase in the number of components of an internal combustion engine. An intake structure S for an internal combustion engine according to one embodiment comprises: a partition 62 that is provided in an intake passage 38 connected to a combustion chamber 20 so as to separate the intake passage into a first intake passage 64 and a second intake passage 66, and that has a communication part 102 that allows communication between the first intake passage 64 and the second intake passage 66; and a curved part 100 of the intake passage 38 provided upstream of the communication part 102. The curved part 100 is formed such that when a straight line IL parallel to the axis 40AX of an intake path 40a connected to the upstream side of the curved part 100 is determined, the straight line IL passes through the inside of the intake path 40a and extends from the second intake passage 66 to the first intake passage 64 via the communication part 102.
