Description

Air inlet pipe for improving air inflow of engine and air inlet noise

Technical Field

The utility model relates to the technical field of air inlet structures of automobile engines, in particular to an air inlet pipe for improving air inflow of an engine and air inlet noise.

Background

With the higher and higher living standard of people, the quality requirement on the vehicle is more and more strict, wherein NVH is a core factor related to the quality of the vehicle, the improvement of the NVH performance of the vehicle is a factor which must be considered in the current vehicle design, and the intake noise of the engine is a key dimension influencing the NVH performance, so that the important work content in the design and development of the intake noise vehicle of the engine is optimized.

Disclosure of Invention

The utility model aims to provide an air inlet pipe for improving air inflow of an engine and air inlet noise.

The air inlet pipe for improving the air input of the engine and improving the air inlet noise comprises an air inlet pipe body, and is characterized in that the air inlet pipe body comprises a first air inlet pipe section, a second air inlet pipe section and a third air inlet pipe section, the front end of the first air inlet pipe section is a first air inlet, the front end of the second air inlet pipe section is a second air inlet, the rear end of the first air inlet pipe section is communicated with the rear end of the second air inlet pipe section and is connected with the front end of the third air inlet pipe section, and the rear end of the third air inlet pipe section is an air outlet.

Further, the first air inlet pipe section is a bent pipe with a short length, and the second air inlet pipe section is a bent pipe with a long length. Not only can promote the height of air inlet like this through the return bend, reduce the air inlet possibility of wading to the width that can promote the second air inlet can be set up in water tank crossbeam rear portion side below position to the setting of the second intake pipe section of longer length, promotes the air input, can make simultaneously with intake-tube connection's air cleaner can set up, reduce the interference with all round spare probably.

Furthermore, the radial cross section of the first air inlet pipe section and the radial cross section of the second air inlet pipe section are both flat and long strips. This makes it possible to expand the intake port in the lateral direction, providing a larger amount of intake air.

Furthermore, the two sides of the front end of the first air inlet pipe section and the two sides of the front end of the second air inlet pipe section are respectively provided with a fixing lug part used for connecting a water tank cross beam.

The air inlet pipe for improving the air inflow of the engine and improving the air inlet noise is used for optimizing the air inlet noise of the engine, and the number, the layout mode, the trend and other structural characteristics of the air inlets of the air inlet pipe are optimized by combining the surrounding environment of the air inlet pipe, so that the air inflow of the engine is increased while the air inlet noise of the engine is optimized, and the performance of the engine is improved.

Detailed Description

The following describes embodiments of the present invention, such as shapes and structures of respective members, mutual positions and connection relationships between respective portions, and actions and operation principles of the respective portions, in further detail, with reference to the accompanying drawings.

Referring to fig. 1 to 4, the intake pipe for improving the air intake amount and improving the intake noise of the engine according to the present invention includes an intake pipe body 1, the intake pipe body 1 includes a first intake pipe section 1A, a second intake pipe section 1B, and a third intake pipe section 1C, the front end of the first intake pipe section 1A is a first air inlet 11, the front end of the second intake pipe section 1B is a second air inlet 12, the rear end of the first intake pipe section 1A is communicated with the rear end of the second intake pipe section 1B and is connected to the front end of the third intake pipe section 1C, and the rear end of the third intake pipe section 1C is an air outlet 13.

In a preferred embodiment, the first intake pipe section 1A is a short-length elbow pipe, and the second intake pipe section 1B is a long-length elbow pipe. Therefore, the height of the air inlet can be improved through the elbow, the wading possibility of the air inlet is reduced, the width of the second air inlet 12 can be improved due to the arrangement of the second air inlet pipe section 1B with a long length, the air inflow is improved, meanwhile, the air filter 2 connected with the air inlet pipe can be arranged at the lower position of the rear side of the water tank cross beam 3, and the possibility of interference with peripheral parts is reduced as shown in fig. 5.

Preferably, the radial cross section of the first air inlet pipe section 1A and the radial cross section of the second air inlet pipe section 1B are both flat and long. This makes it possible to expand the intake port in the lateral direction, providing a larger amount of intake air.

Preferably, both sides of the front end of the first air inlet pipe section 1A and both sides of the front end of the second air inlet pipe section 1B are provided with fixing lugs 14 for connecting the water tank cross beam 3.

When the air inlet pipe is installed, the first air inlet 11 and the second air inlet 12 are fixed on the water tank cross beam 3 through the fixing lug parts 14, the whole trend of the air inlet pipe body 1 is ensured to ensure a safety clearance which is more than or equal to 15mm with peripheral parts such as an engine, a water tank and the like, and then the air outlet 13 is connected with the air inlet of the air filter 2.

The utility model has been described in connection with the accompanying drawings, it is to be understood that the utility model is not limited in its application to the details of construction and the arrangement of the components set forth in the following description, as long as the utility model is capable of being practiced without modification in any way whatsoever, and is capable of other applications without departing from the spirit and scope of the utility model as defined by the appended claims.
