Abstract
An intake system component of an internal combustion engine includes a porous material product and a resin molded portion. The porous material product is formed from a porous material and includes an outer edge and a general portion. The resin molded portion encompasses the outer edge and is formed integrally with the porous material product. The general portion is located outside the resin molded portion. The outer edge has a lower filling density than the general portion.
Claims5
An intake system component of an internal combustion engine, the intake system component comprising:
- a porous material product formed from a porous material and including an outer edge and a general portion;
- and
- a resin molded portion encompassing the outer edge and formed integrally with the porous material product, wherein
- the general portion is located outside the resin molded portion, and
- the outer edge has a lower filling density than the general portion.
A method for manufacturing an intake system component of an internal combustion engine, wherein the intake system component includes a porous material product formed from a porous material and including an outer edge and a general portion, and a resin molded portion encompassing the outer edge and formed integrally with the porous material product, the method comprising:
- forming the porous material product that includes the general portion and a low-density portion by thermally pressing the porous material, wherein the low-density portion has a lower filling density than the general portion;
- and
- molding the resin molded portion by injecting molten resin into a cavity of a mold with at least a distal portion of the low-density portion inserted into the cavity.
