Intake passage structure for an internal combustion engine |
| 摘要 |
An intake passage structure for an internal combustion engine has a first passage portion where a throttle valve is disposed and a second passage portion, downstream of the fist passage portion, where a mesh member is disposed. A relationship S1</= alpha S2 holds between a cross-sectional area S1 of the first passage portion and a cross-sectional area S2 of the second passage portion where alpha is an open area rate of the mesh member. A clearance may be provided between a periphery of the mesh member and an inside surface of the intake pipe where the mesh member is disposed.
