Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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. 2. The intake system component according to claim 1 , wherein the porous material product further includes a buffer portion located between the resin molded portion and the general portion, and the buffer portion has a lower filling density than the general portion. 3. The intake system component according to claim 1 , wherein the intake system component of the internal combustion engine includes a housing of an air cleaner, the housing includes a periphery defining an opening, and the resin molded portion includes a flange located on the periphery of the housing. 4. 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. 5. The method according to claim 4 , wherein the low-density portion includes the distal portion and a continuous portion that is continuous with the distal portion, and the method further comprises compressing the continuous portion by the mold with the distal portion of the low-density portion inserted into the cavity of the mold.
