Abstract
The invention relates to an exhaust pipe for an automobile. The exhaust pipe for the automobile is characterized by comprising an exhaust pipe body provided with an exhaust channel; the exhaust pipe body comprises an exhaust main pipe, wherein one end of the exhaust main pipe is used for being communicated with an automobile exhaust port, and the other end of the exhaust main pipe is provided with two or more exhaust branch pipes in a divided mode; one end of each exhaust branch pipe is communicated with the exhaust main pipe, and the other end of each exhaust branch pipe extends in the direction away from the exhaust main pipe; the three exhaust branch pipes are located on the same plane as the exhaust main pipe, and the exhaust branch pipe in the middle is coaxial with the exhaust main pipe; the joints, in the direction of air flow in the exhaust channel, between every two adjacent exhaust branch pipes are provided with dividing baffle sheets respectively in a protruding mode. The exhaust pipe for the automobile has the advantages that the tail gas exhaust noise of an automobile exhaust system can be lowered, the structure is simple, manufacturing and processing are easy, and a muffler does not need to be mounted compared with the prior art.
Description
Technical field
The present invention relates to a kind of outlet pipe for automobile.
Background technique
In recent years, urban motor vehicle increases very fast, incident traffic noise pollution environmental phenomenon also becomes increasingly conspicuous, automobile is noise pollution to the harm that environmental protection is maximum, investigation shows, motor vehicle noise accounts for 85.5% of urban traffic noise, along with the development of automotive energy-saving emission-reducing, require that automobile reduces noise, energy saving consumption.And the topmost noise of automobile is from the vent systems of automobile, i.e. motor vehicle exhaust emission noise, in order to reduce motor vehicle exhaust emission noise, meet the requirement of automobile environment-protection, traditional automobile exhaust system realizes noise elimination noise reduction by fixing a silencer, but acoustic wave filter structure is complicated, and install also inconvenient.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of outlet pipe for automobile, solves the deficiencies in the prior art.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of outlet pipe for automobile, it is characterized in that: comprise the outlet pipe body with exhaust passage, outlet pipe body comprises one end to be responsible for for the exhaust be communicated with automobile exhaust port, the other end fork of exhaust supervisor is provided with two or more exhaust branch pipe, one end of each exhaust branch pipe be responsible for exhaust be respectively communicated with, the other end is vented all to be dorsad responsible for and extends; Described exhaust branch pipe is be responsible in the same plane three with exhaust, and the exhaust branch pipe being positioned at neutral position is responsible for coaxial setting with exhaust; The connecting place in face of the airflow direction in exhaust passage of two adjacent exhaust branch pipes is convexly equipped with shunting catch respectively.
The invention has the beneficial effects as follows: the automobile exhaust pipe adopting said structure, the one end due to exhaust supervisor is used for being communicated with automobile exhaust port, is directly installed on automobile exhaust pipe by exhaust supervisor, easy for installation, and the other end fork of exhaust supervisor is provided with plural exhaust branch pipe, and one end of each exhaust branch pipe is responsible for is communicated with exhaust, the other end is vented supervisor all dorsad and extends, ensure that the exhaust passage of outlet pipe can normal exhaust, each exhaust branch pipe also serves shunting action, the tail gas of outlet pipe is entered by automobile exhaust port, after exhaust supervisor under the shunting action of each exhaust branch pipe, avoid tail gas and concentrate discharge, therefore, it is possible to reduce the emission noise of automobile exhaust system, and structure is simple, manufacture easy processing, hinge structure, can not need to fix a silencer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, the outlet pipe main body of this outlet pipe comprises exhaust supervisor 2, one end of exhaust supervisor 2 is that inlet end, the other end be communicated with automobile exhaust port diverges and be provided with three exhaust branch pipes 4, one end of three exhaust branch pipes 4 is all communicated with exhaust supervisor 2, the other end is the exhaust end being vented supervisor 2 dorsad and extending, and each exhaust branch pipe 4 is all positioned in same plane with exhaust supervisor 2, the exhaust branch pipe being positioned at neutral position is coaxially arranged with exhaust supervisor 2.During concrete use, the inlet end of exhaust supervisor 2 is communicated with automobile exhaust port, vehicle exhaust is made to be entered by the inlet end being vented supervisor 2 like this, after exhaust supervisor 2 and three exhaust branch pipes 4, discharged by the exhaust end of three exhaust branch pipes 4, the passage of exhaust supervisor 2 and three exhaust branch pipes 4 defines the exhaust passage of outlet pipe main body, and the airflow direction of tail gas is flowed to the exhaust end of three exhaust branch pipes 4 by the inlet end being vented supervisor 2 along exhaust passage.Three exhaust branch pipes 4 serve shunting action, and simultaneously in order to ensure that tail gas can fully be shunted, two joints in face of airflow direction of adjacent two exhaust branch pipes 4 are convexly equipped with shunting catch 3 respectively.
In order to reduce tail gas pollution, exhaust supervisor 2 being equipped with on main ternary catalyzing unit 1, three exhaust branch pipes 4 and being equipped with a ternary catalyzing unit 5 respectively.
The intermediate section of described exhaust supervisor 2 is bending section, and this bending section can play the effect of buffering to tail gas, be conducive to reducing discharge noise.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
