Description
- 1. Field of the Invention
- The present invention relates to an improved structure of a muffler at the rear end of an exhaust pipe, more particularly to a muffler comprising a tapered inner pipe inside a tapered conical outer pipe, and further having a tapered sleeve being disposed in the inner pipe proximate to the rear end of the inner pipe to increase the output torque of the engine and reduce the noise, and by the design of a gas-receiving pipe with a French connector being soldered to the front end of the external pipe, and an n-shaped fixing bracket being soldered to the external pipe to provide an easy installation for all sorts of vehicles.
- 2. Description of the Related Art
- The conventional muffler used for the exhaust pipe of vehicles has existing shortcomings or inferior designs. Please refer to FIG. 1 for the prior art mufflers. The inner pipe having silencing holes is disposed inside the outer pipe, and the silencing cotton is being wrapped around the wall of the inner pipe. However, the shortcoming of this design is not able to enhance the torque of the engine, and since the airflow directly collides on the pipe wall to generate a larger noise. Furthermore, it needs to preinstall by soldering a connecting pipe and positioning bar according to the specification of a specific vehicle model at the front end and external surface of the external pipe. It makes the installation difficult, time-consuming, and waste of labor.
- In summation of the above description about the prior art waiting for a breakthrough, the present inventor herein enhances the performance of the conventional structure by performing research and development to increase the torque output of the engine, reduce the noise, and provides easy installation for all sorts of vehicles.
- The main objective of this invention is to provide an improved structure of a muffler at the rear of the exhaust pipe, which utilizes the coupling of the tapered conical shape of the external pipe and the tapered inner tape and the densely distributed silencing holes on the wall of the inner pipe, in addition to the silencing cotton wrapped around the external side, and a tapered sleeve being installed to the internal rim at the rear end of the inner pipe to form an appropriate backpressure in order to enhance the torque output of the engine.
- The secondary objective of the present invention is to provide an improved structure of a muffler at the rear of the exhaust pipe, which utilizes a tapered inner pipe and a tapered sleeve at the internal rim proximate to the rear end of the inner pipe to accelerate the airflow. The distance between the inner pipe and the external pipe gradually increases thereby reduce the noise generated by airflow collision on the external pipe.
- Another objective of the present invention is to provide an improved structure of a muffler at the rear of the exhaust pipe, which uses a design of a gas-receiving pipe with a French connector and an n-shaped bracket located at an appropriate position on the external side at the rear end of the external pipe to facilitate the installation for different types of vehicles.
- To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and its performance, we use a preferred embodiment together with the attached drawings for the detailed description of the invention.
- Other objects, features, and advantages of the invention will become apparent from the following detailed description of the preferred but non-limiting embodiment. The description is made with reference to the accompanying drawings, in which:
- FIG. 1 illustrates the cross-section of the conventional muffler at the rear of the exhaust pipe.
- FIG. 2 illustrates the three-dimensional appearance of the conventional muffler at the rear of the exhaust pipe.
- FIG. 3 illustrates the three-dimensional appearance of the muffler at the rear of the exhaust pipe according to the present invention.
- FIG. 4 is a three-dimensional diagram illustrating a part of the cross-section of the muffler at the rear of the exhaust pipe according to the present invention.
- FIG. 5 is a three-dimensional diagram illustrating the cross-section of the muffler at the rear of the exhaust pipe according to the present invention.
- FIG. 6 is a three-dimensional diagram illustrating the installation of a preferred embodiment according to the present invention.
- Please refer to FIGS. 4 and 5 for an improved structure of a muffle at the rear of the exhaust pipe according to the present invention. The muffler at the rear of the exhaust pipe comprises an
external pipe 1, aninner pipe 2, asleeve 3, a gas-receivingpipe 4, adecorative lid 5, and an n-shaped fixing bracket 6. The detailed structure is described below: - The
external pipe 1 is a hollow ascending tapered pipe, having a gas-receivingpipe 4 with aFrench connector 41 soldered to the front end of theexternal pipe 1. The internal rim of theexternal pipe 1 has an opening equal in internal diameter with that of the taperedinner pipe 2. The wall of theinner pipe 2 has a plurality of densely distributedsilencing holes 21, and a silencingcotton 7 being wrapped around the external edge of theinner pipe 2. Asleeve 3 having aconical pipe opening 31 is disposed at the internal edge proximate to the rear end of theinner pipe 2, and the diameter of the opening of thesleeve 3 exactly fits into wall hole at the inner edge surface of theinner pipe 2. The end of thesleeve 3 slightly passes through theedge surface 11 at the rear end of theexternal pipe 1, and adecorative lid 5 covers therear edge surface 11 of theexternal pipe 1. The center of suchdecorative lid 5 forms a divergingconical hole 51 that exactly fits the rear end of thesleeve 3 into the centralconical hole 51, and an appropriate part of thedecorative lid 5 being latched into aringed groove 52. Theringed groove 52 has penetratingholes 520 for mounting therear edge surface 11 of theexternal pipe 1 to the corresponding position of the solderednuts 110 by thescrews 53. - Please refer to FIG. 5 for the structural function of the present invention. When the waste gas enters the gas-receiving
pipe 4 having aFrench connector 41 of theinner pipe 2, due to the larger cross-sectional area of the front end opening of theinner pipe 2, the airflow will slow down to fill up and then accelerate according to the tapered shape of theinner pipe 2. The airflow is affected by the tapered end of thesleeve 3 proximate to its rear end opening; it produces an appropriate backpressure to increase the torque output of the engine. Furthermore, the airflow in theinner pipe 2 accelerating in theexternal pipe 1 with opposite tapered direction can reduce the noise produced by the airflow collision on theexternal pipe 1. - The assembly of the present invention as shown in FIG. 6 has an n-
shaped fixing bracket 6 being soldered to an appropriate position at the rear section proximate to the external side of theexternal pipe 1. Such n-shape fixing bracket 6 has a plurality offixing holes 61 to mount thebar 8 onto thefixing bracket 6. The gas-receivingpipe 4 having aFrench connector 41 at the front end of the external pipe can be coupled to different types of connectingpipes 9. It makes the installation of the present invention much easier, and is unlike the inconvenient prior art technology that needs to solder the fixing bar and connectingpipe 9 to the muffler. - In summation of the above description, the present invention herein overcomes the shortcomings of the conventional mufflers and further complies with the patent application requirements and is submitted to the Patent and Trademark Office for review and granting of the commensurate patent rights.
- While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
