Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of intake guide vanes for automotive throttle valves, specifically relating to a novel intake guide vane. Background Technology
[0002] When the engine throttle is open, vortex noise is generated at the upper and lower edges of the throttle valve plate, causing throttle whine. Currently, the throttle valve of engines on the market is directly installed on the intake manifold, which cannot improve the throttle whine problem. Utility Model Content
[0003] The purpose of this invention is to add an intake deflector between the intake manifold and the throttle valve, which can disrupt the vortex structure generated downstream of the throttle valve, thereby reducing the whistling sound generated when the accelerator is pressed hard and improving NVH performance. The technical solution is as follows:
[0004] A novel air intake deflector, characterized in that: it includes an air intake deflector body 1 and a vent 4 disposed at the middle of the front surface of the air intake deflector body 1; a plurality of guide teeth 3 are evenly distributed on the inner side surface of the vent 4; a plurality of mounting holes 5 are provided on the front surface of the air intake deflector body 1; a sealing ring 2 is connected at the middle of the front surface of the air intake deflector body 1; the sealing ring 2 is disposed at the outer edge of the front surface of the vent 4; the sealing ring 2 and the vent 4 are concentric circles; the sealing ring 2 is conical in shape; a plurality of mounting holes 5 are disposed at the four corners of the front surface of the air intake deflector body 1; and the guide teeth 3 are perpendicular to the inner side surface of the vent 4.
[0005] The beneficial effects of this utility model are as follows: by adding an intake guide plate between the intake manifold and the throttle valve, the vortex structure generated downstream of the throttle valve can be destroyed, thereby reducing the whistling sound generated when the accelerator is pressed hard and improving NVH performance.

[0009] Reference Figure 1 Figure 2The novel air intake deflector is characterized by comprising an air intake deflector body 1 and a vent 4 disposed at the middle of the front surface of the air intake deflector body 1. A plurality of guide teeth 3 are evenly distributed on the inner side surface of the vent 4. A plurality of mounting holes 5 are provided on the front surface of the air intake deflector body 1. A sealing ring 2 is connected at the middle of the front surface of the air intake deflector body 1. The sealing ring 2 is disposed at the outer edge of the front surface of the vent 4. The sealing ring 2 and the vent 4 are concentric circles. The sealing ring 2 is conical in shape. A plurality of mounting holes 5 are disposed at the four corners of the front surface of the air intake deflector body 1. The guide teeth 3 are perpendicular to the inner side surface of the vent 4.
[0010] When in use, first place the main body 1 of the intake guide plate between the intake pipe and the throttle valve, and tighten the bolts through the mounting hole 5 to fix the main body 1 of the intake guide plate. The vortex gas generated by the throttle valve passes through the vent hole 4, and at the same time, the guide teeth 3 break the vortex gas to reduce the whistling sound generated when pressing the accelerator.
[0011] When in use, sealing ring 2 reduces gas leakage and the generation of other noises.
[0012] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
