Embodiment Construction

[0016] will now refer to Figure 1 to Figure 4 One embodiment will be described.

[0017] refer to figure 1 , an air filter is arranged in the intake passage of the internal combustion engine of the vehicle. The air filter comprises a first housing 10 with an inlet 18 , a second housing 20 with an outlet 28 and a filter element 30 . The filter element 30 is located between the upper opening 11 of the first housing 10 and the lower opening 21 of the second housing 20 opposite to the upper opening 11 .

[0018] The first housing 10 includes a bottom wall 13 and a peripheral wall 12 surrounding the upper opening 11 . An annular flange 16 protrudes from the periphery of the upper opening 11 toward the outside. The inlet 18 is tubular and protrudes from the outer surface of the peripheral wall 12 .

[0019] The second housing 20 includes a top wall 23 and a peripheral wall 22 surrounding the lower opening 21 . An annular flange 26 protrudes from the periphery of the lower ope...

Abstract

An intake system component of an internal combustion engine and a method for manufacturing an intake system component of an internal combustion engine. 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.

Description

technical field [0001] The present invention relates to an intake system part of an internal combustion engine and a manufacturing method thereof. The intake system part of an internal combustion engine includes a porous material product formed of a porous material and a resin molded part surrounding the outer edge of the porous material product and integrally formed with the porous material product. Background technique [0002] Japanese Patent Laid-Open No. 2002-21660 describes an example of an air cleaner for a vehicle internal combustion engine used as one type of intake system component. Air filters include articles of porous material formed from porous materials such as filter paper, nonwoven fabrics, or open cell sponges. The article of porous material forms the wall of the housing of the air cleaner. This publication discloses that a porous material article is inserted when molding a resin molded portion of a casing. [0003] When an article of porous material is u...
