Title:
AIR INTAKE DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2023/053308
Kind Code:
A1
Abstract:
Provided is an air intake device for an internal combustion engine including an air intake passage 80, an air intake passage pipe 6; and a throttle valve 75. The air intake passage pipe 6 is located downstream of a throttle body 7, is equipped with a dividing wall 81 for dividing the air intake passage pipe into a tumble flow path 80A and a main flow path 80B, and has a resonator 100 that is connected with the intake passage 80 via a connecting pipe 101. The air intake passage pipe 6 has: an intake air control valve 65 that is located downstream of the throttle valve 75 and that controls the ratio between the air intake flow rates of the tumble flow path 80A and the main flow path 80B; and a connecting hole 102 that is open to the connecting pipe 101. The connecting pipe 101 is equipped with an air volume adjustment valve 110 that opens and closes the interior of the air intake passage pipe 6, and thus enhances the flow of tumble flow and improves combustion efficiency.
