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 S.sub.1 .ltoreq..alpha.S.sub.2 holds between a cross-sectional area S.sub.1 of the first passage portion and a cross-sectional area S.sub.2 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.
