Title:
INTAKE SYSTEM OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2018150815
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To miniaturize a throttle body with an interlocking mechanism.SOLUTION: An intake device of an internal combustion engine has: a throttle body 7 with an intake path 70; a throttle valve 71 having a throttle valve shaft 71a vertical to a flow direction F of the intake path; a tumble valve 72 having a tumble valve shaft 72a vertical to the flow direction of the intake path on its downstream side; a throttle drum 73 rotated integrally with the throttle valve by a throttle opening degree requirement mechanism 75; a throttle lever 74 rotated integrally with the throttle valve and having a driving part 74a; and a tumble lever 77 having a driven part 77a rotated integrally with the tumble valve and that can contact and separate from the driving part. It is also provided with an interlocking mechanism 100 capable of interlocking and rotating the tumble lever in the same rotation direction as the throttle lever. A contact starting point X of the driving part and the driven part is positioned on an upper stream side than a downstream side end 73d of the throttle drum in the flow direction of the intake path.SELECTED DRAWING: Figure 5
