Abstract

Provided is an air induction device for an automobile capable of reducing suction noise generated by the suction air to improve stillness in driving. The air induction device for an automobile includes: a main body having a suction manifold mounted on an engine, a throttle body installed in the suction manifold, an air cleaner connected to the throttle body by an air suction duct, an air suction pipe connected to the air cleaner to introduce the external air and having an opening installed at a rear part of a radiator, a suction port formed at a front part thereof, and a space formed therein;a discharge pipe formed at one side of the main body and connected to the suction pipe to be in communication with the space; ; and a resonance part formed inside the main body to remove noise generated during air suction, characterized in that the resonance part is formed of a cylindrical pipe and has a closed end opposite to the discharge pipe and an oval opening formed at the other end toward the discharge pipe, and the opening is formed to be connected to an inlet port of the discharge pipe and installed at a rear surface inside the main body to be opposite to the suction port of the mainbody.

Description

technical field [0001] The present invention relates to an automobile air intake device, and more particularly, to an automobile air intake device capable of reducing suction noise when air is sucked through an air filter of a running automobile. Background technique [0002] Typically, an automotive air intake includes an air filter that filters dust or other matter from air drawn into the cylinders and an intake manifold that distributes the filtered air into the cylinders. [0003] Such as figure 1 As shown, the conventional air intake device includes a suction branch pipe 400A installed on the engine 500A, a throttle valve body 350A arranged in the suction branch pipe 400A, and an air filter 300A connected to the throttle valve body 350A through the suction pipe 340A. , and an air suction pipe 200A connected to the air cleaner 300A and introducing outside air. [0004] In addition, an opening formed at the front end of the air intake duct 200A is disposed at the rear o...
