Abstract (en)
An intake manifold including an intake manifold body (15) including a collector (5) and a plurality of branches (2, 3. 4) joined with each other through a connecting wall (7, 8), and a resonator (6) including a resonator body member (14) fixed onto an outer surface of the intake manifold body. Each of the branches has a thickness larger than that of the connecting wall. The resonator includes a resonator neck (30) and a resonator volume chamber (31) communicated with the collector through the resonator neck. The resonator neck has a resonator neck passage (29) formed between a pair of opposed resonator neck walls connected with the resonator body member and the outer surface of the intake manifold body. The resonator neck is disposed above one of the branches and extends along the one of the branches.
