Description

Exhaust pipe improved structure

The present invention relates to the technical field of vehicle or mechanical exhaust, in particular to the technical category of introducing exhaust gas with or without muffler to achieve the effect of changing exhaust volume.

The existing variable-volume exhaust pipes that use noise-absorbing cotton to absorb exhaust noise are mainly used in the structure of the main exhaust pipe, the manifold exhaust pipe, the air intake pipe and the control valve to guide the flow of exhaust gas according to the demand. The exhaust gas is introduced into the silencing cotton, and the noise generated by the exhaust gas is absorbed through the silencing cotton. In addition, the muffler loaded with muffler cotton is generally installed and wrapped on the manifold. In terms of structural design, this design will make the distance between the manifold and the main pipe larger, resulting in this variable volume The overall structure of the exhaust pipe will take up more space and the cost of transportation will be higher.

Therefore, in view of the above-mentioned conventional variable volume exhaust pipe structure, which has a large space and causes high transportation costs, the new creator has worked hard to develop a kind of muffler installed and wrapped in the main exhaust pipe, The manifold pipe and the air inlet pipe, and then the exhaust pipe which is integrally covered with the outer cover, so that the space occupied by the overall exhaust pipe structure is effectively reduced, the transportation is more convenient, and the transportation cost is lower. Therefore, the main purpose of the present invention is to reduce the space occupied by the improved structure of the exhaust pipe, thereby reducing the transportation cost of transporting the exhaust pipe parts.

In order to achieve the above purpose, the new model uses the following technical means: About the new model is an improved structure of the exhaust pipe, which is used to install a vehicle or machine The exhaust end of the mechanical engine includes: an outer cover forming an enclosed inner space; a muffler, the muffler is located in the inner space; and a muffler cotton, the muffler cotton is filled in the muffler Peripheral; a first row of tubes that penetrates the housing, the muffler cotton and the silencer; a manifold, the manifold extends from a branch of the first row of tubes and penetrates the housing , The silencer cotton and the silencer, the open end of which is tightly wrapped in the silencer, and the length of the manifold is not limited, can be adjusted according to demand; one air inlet, the air inlet is made by the first row Another branch extension, whose open end is tightly wrapped in the muffler; and a control valve, which is located in the channel of the first row of pipes, between the opening leading to the manifold and the leading The middle section of the opening of the air inlet pipe; by covering the first exhaust pipe, the manifold exhaust pipe and the air inlet pipe with the muffler, and then covering the whole with the outer cover and the muffler cotton, the entire exhaust can be effectively reduced The space occupied by the tube structure.

As in the above technical means, the muffler has a hollow structure, and a plurality of penetrating air inlet holes are provided on the casing.

As mentioned above, the tail end of the first row of pipes may or may not be connected to the second row of pipes.

As described in the above technical means, the air intake tube can be set to an in-line type completely submerged into the muffler, or an explicit type and an explicit type submerged into the muffler, and the length of the air intake tube is not The limit can be adjusted according to demand.

As the above technical means, when the control valve is opened, the exhaust gas is directly discharged through the first exhaust pipe without silencer; when the control valve is closed, the exhaust gas flows into the manifold and the silencer, and is installed in the peripheral internal space The sound-absorbing cotton absorbs without sound-absorbing.

According to the above technical means, the present invention depends on the type of vehicle or mechanical exhaust pipe, the end of the first exhaust pipe may be connected or not connected to the second exhaust pipe, and the air inlet pipe may also be provided as the aforementioned in-line type Type or external type, so the implementation of the new model includes embedded single-row tube type, external single-row tube type, embedded multi-row tube type, external multi-row tube type Improved trachea structure.

As the above technical means, wherein the first row of tubes cannot be mesh holes (ie, in front of the valve, outside the barrel), and the second row of tubes, manifold pipes, and air inlet pipes are all set as mesh tubes or flat tubes or mesh holes The tubes and flat tubes are mixed and used; the length of the manifold and the air inlet tube is not limited.

The new technology uses the above technical means, compared with the conventional structure, it can greatly reduce the overall space occupied by the exhaust pipe improved structure, and the transportation cost can also be greatly reduced.

Therefore, the new model can achieve the size of the exhaust sound wave, the back pressure, and the low level of the operator's expectation by either the mesh tube or the general flat tube, and the length and length of the manifold and the air inlet tube. The obvious effect of turning torque, high turning horsepower, etc. is exerted, and it demands real customized production.
