An intake manifold for an internal combustion engine. A first separable part includes an independent intake passage, a first recess, and a first joint section. The independent intake passage has a downstream open end connected to more than one intake port in the engine. The first recess is disposed on a side of the independent intake passage, and has an open end adjacent to an upstream open end of the independent intake passage. The first joint section surrounds the upstream open end of the independent passage and the periphery of the first recess. A second separable part includes a second joint section to abut the first joint section, and a second recess having an opened internal circumference of the second joint section and being disposed opposite to the independent intake passage. Intake air is introduced through the first and second recesses to the intake passage when the first and second separable parts are joined together. A communication hole is defined in the second separable part to communicate to outside. A third separable part covers the communication hole from outward. A resonator includes an outer wall defined by the second and third separable parts.
Description
Technical field [0001] The present invention relates to an intake manifold of an internal combustion engine, and more particularly to an intake manifold in an internal combustion engine in which a surge tank and an intake passage are located in a grooved groove formed by connecting synthetic resin. In the space formed by the separating part, a resonator communicating with the surge tank is provided in the form of a simple separable structure. Background technique [0002] In an internal combustion engine with a plurality of cylinders mounted on a vehicle, an intake manifold is arranged at the intake end toward the engine to introduce air to the cylinders. See Japanese Patent Publication No. H05-60023, No. H10-18849 and No. H10-339224. [0003] In the intake manifold of a conventional internal combustion engine, the surge chamber and the intake passage are located in a space formed by connecting separable parts with grooves formed of synthetic resin.
