Description

Intake noise blocking device of car

The present invention relates to an intake duct connected to an air cleaner. In particular, the intake duct for introducing air into the air cleaner is separated into a first intake duct and a second intake duct so that two intake ports for sucking air face each other. The first noise blocking plate and the second noise blocking plate are placed at the end portions of the first intake duct and the second intake duct to induce the intake of air, thereby releasing the noise generated from the engine to the intake duct through the air cleaner. The present invention relates to an intake noise blocking device of a vehicle which reduces intake noise by canceling each other from two opposed noise blocking plates.

In general, in order to operate an engine of an automobile, fuel such as gasoline, diesel, etc. must be supplied, and after that, the fuel is diluted with air so as to be suitable for supplying the engine and supplied to the engine through the intake manifold, and then the spark plug To explode fuel and start the engine.

As such, the air supplied to the fuel must separate foreign substances such as dust and the like mixed with the air in advance in the air purifier, and supply only the purified air to the engine.

1 is a view illustrating a conventional general air purification and intake system. Referring to the configuration of a conventional air intake apparatus, an intake duct 1 for introducing external air and an intake duct 1 are sucked into the intake duct 1. An air purifier (3) for cleanly purifying air using a filter or the like mounted therein, an air suction line (5) for moving the purified air from the air cleaner (3), and the air suction line (5) It consists of an intake manifold (7) for separating and supplying air sucked through the engine (9).

In this way, the configured air intake system intakes the outside air through the intake duct (1) to filter and cleanly clean the air cleaner (3), and then purifies the air purified through the air inlet line (5) intake manifold (7) It is supplied to each cylinder of the engine 9 in a state separated from).

By the way, the intake duct of the conventional air intake system has a structure that is formed to protrude in a straight line from the air cleaner so as to suck the air, so that the engine explosion sound generated from the engine is the air inlet line, air cleaner and intake duct It is discharged to the engine room through the exhaust air intake noise is supplied to the interior of the vehicle has a problem that harms the quietness of the vehicle.

The present invention has been made in view of this point, the intake duct for introducing the air to the air cleaner is separated into the first intake duct and the second intake duct to intake the two intakes facing each other and now arranged When the noise generated from the engine is released into the intake duct through the air cleaner by inducing air intake by holding the first noise shield plate and the second noise shield plate at the ends of the first intake duct and the second intake duct, The purpose of the present invention is to reduce intake noise by canceling and canceling each other in the opposing noise blocking plate.

An object of the present invention is to provide an air intake system including an air purifier for purifying air and an intake manifold for supplying air purged from the air purifier to an engine through an air inlet line, wherein the air purifier is bifurcated to both sides of the air purifier. The first noise duct is formed in the shape of the first intake duct and the second intake duct formed in a □ -shape so as to correspond to the air inlet, and the first noise formed protruding in the shape of a trumpet at the end portions of the first and second intake ducts It is achieved by providing an intake noise blocking device for a vehicle composed of a blocking plate and a second noise blocking plate.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated in detail based on an accompanying drawing.

First, as shown in Figures 2 and 3, looking at the configuration of the intake noise blocking device of the present invention, the air purifier 30 for purifying the air, and the air purified in the air purifier 30 air inlet line In the intake system composed of the intake manifold 50 to be supplied to the engine 60 through the 40, the air inlet 14 is protruded to both sides of the air cleaner 30 and bent in a symmetrical state twice each Trumpet at end portions of the first intake duct 10 and the second intake duct 20 and the first intake duct 10 and the second intake duct 20 so as to correspond to the? The first noise blocking plate 12 and the second noise blocking plate 22 are formed to protrude in shape.

In addition, the first noise blocking plate 12 and the second noise blocking plate 22 may be integrally formed in the first intake duct 10 and the second intake duct 20 or may be manufactured as a separate part. It can be used to assemble, it is preferable to use a soft plastic material in order to improve the suction of noise.

Hereinafter, the operation of the present invention will be described.

Looking at the state of use of one embodiment of the present invention, first driving the vehicle equipped with the present invention, the first intake duct 10 and the first after inhaling air through the air intake (14, 24) 2, the air sucked through the intake duct 20 is moved, and the air introduced into the air cleaner 30 is filtered by an internal filter and then passed through the intake manifold 50 through the air inlet line 40. It is introduced into the cylinder of the engine 60 mixed with gasoline.

As such, the noise generated by the engine 60 passes through the air inlet line 40, through the air cleaner 30, through the first intake duct 10, and through the second intake duct 20. 14) and 24 are discharged to the outside.

On the other hand, the noise discharged to the two air intakes (14, 24) of the intake duct 10 (20) is opposed to each other and the noise is hit, and furthermore the noise is the first noise blocking plate 12 and the second noise blocking plate Blocked at (22) can not be discharged to the outside, so that the noise hit each other is not only weakened by itself, but also the noise discharged to the air intake (14, 24) hit the other noise blocking plate (12) (22) facing Since the air inlet (14, 24) of the other side is inclined, the noise leaking to the outside is significantly reduced.

Therefore, when the intake noise blocking device of the vehicle according to the present invention is used as described above, the intake duct for introducing air into the air cleaner is separated into two first intake ducts and a second intake duct to inhale air. The noise generated from the engine is induced by placing the inlets facing each other and inducing air by holding the first noise blocking plate and the second noise blocking plate at the ends of the first intake duct and the second intake duct. When it is discharged through the intake duct through the two opposing first and second noise shielding plate cancels each other, thereby significantly reducing the intake noise is a very useful and effective invention for running the car quietly.
