Embodiment Construction

[0015] will now refer to Figure 1 to Figure 4 One embodiment of an intake system component arranged in an engine compartment of a vehicle will be described. In the following description, the term “inside” refers to the side of the object that is close to the center of the fiber portion 6 , and the term “outside” refers to the side of the object away from the center of the fiber portion 6 .

[0016] figure 1 The intake system of the internal combustion engine 1 installed in the engine compartment of the vehicle is schematically shown. The intake system of the internal combustion engine 1 includes intake system components such as an intake duct 2 forming an intake passage 4 and an air cleaner 3 . Air is drawn into internal combustion engine 1 via intake duct 4 . The intake duct 2 is connected to an air cleaner 3 and is located on the upstream side of the air cleaner 3 in the intake system of the internal combustion engine 1 .

[0017] Such as figure 2 As shown, the intake...

Abstract

An intake system component arranged in an engine compartment of a vehicle includes a side wall that forms an intake passage. The side wall includes a non-breathable layer, an inner noise absorption layer, and an outer noise absorption layer. The non-breathable layer is formed from a non-breathable material. The inner noise absorption layer is located at an inner side of the non-breathable layer and formed from a breathable material. The outer noise absorption layer is located at an outer side of the non-breathable layer and formed from a breathable material.

Description

technical field [0001] The invention relates to an air intake system component. Background technique [0002] In a vehicle such as an automobile, an intake system component (for example, an intake duct) including a side wall defining an intake passage is arranged in an engine compartment. It is desired to reduce intake noise in such an intake duct (intake passage). Japanese Patent Laid-Open No. 11-343939 describes an intake duct having a gas-permeable side wall that can release sound pressure from the intake duct (intake passage). This reduces intake noise by limiting the generation of standing waves caused by intake noise in the intake duct. [0003] When a vehicle engine is running, the engine also produces noise that affects the noise in the engine compartment. Therefore, it is desired to reduce the noise generated outside the intake passage in addition to the noise generated within the intake passage in the engine compartment. However, when an intake duct such as tha...
