Description
- 1. Field of the Invention
- The present invention relates to tailpipe of automotive vehicle and more particularly to such a tailpipe of automotive vehicle with improved characteristics.
- 2. Description of Related Art
- A conventional exhaust pipe of an internal combustion engine comprises an expansion chamber, a resonant chamber at the rear of the expansion chamber, and a plurality of perforated pipes disposed in both chambers, each pipe being enclosed by glass fibers or sound-absorbing material for silencing noise. Exhaust from the engine may flow into the chambers through apertures of the pipes. This can build a back pressure in the chambers, resulting in a partial back flow of exhaust into the engine. As an end, output torque of the engine is lowered due to incomplete combustion of the engine. U.S. Pat. No. 4,792,014 discloses an excessively long tailpipe of internal combustion engine such that it cannot be readily mounted at the exhaust pipe. Instead, a modification of the existing exhaust pipe is required. This is not advantageous. Further, noise is serious when a car incorporated such tailpipe is driving at high speed, especially more than 100 km per hour. Hence, a need for improvement exists.
- It is an object of the present invention to provide a tailpipe of automotive vehicle. The tailpipe has a reduced length so as to be readily mounted at an exhaust pipe. The tailpipe comprises an outer tube constructed by incorporating the principles of venturi tube. By utilizing the present invention, it is possible of carrying out a more complete combustion, reducing air pollution, and further silencing noise.
- To achieve the above and other objects, the present invention provides a tailpipe of an automotive vehicle, comprising a front tube including two flared ends and an intermediate neck having a plurality of rows of apertures wherein one flared end of the front tube is coupled to a muffler; a rear tube having a flared end; an outer tube surrounded a rear portion of the front tube and the whole rear tube, the outer tube including a flared front end, a cylindrical section, an enlarged section, and a rear section having an inward extending rim at an opening thereof; and a plurality of twisted blades equally spaced apart around the rear tube and connected to the front, the rear, and the outer tubes, each blade having a plurality of apertures, wherein a stream of exhaust from the muffler entering into the neck is divided into a first component flowing through the rear tube, and a second component flowing into a space between the neck and the outer tube through the apertures, the second component is mixed with air drawn from the front end of the outer tube to form a third component, the third component flows to a rear of the outer tube after being baffled by the blades and passing a plurality of channels each between two adjacent blades to form a fourth component in a form of whirlwind, and a fifth component in a form of whirlwind is formed by mixing the fourth component with the first component after leaving the tailpipe.
- In one aspect of the present invention the outer tube has a length of about 12 cm, the front tube has a length of about 12.5 cm, and the tailpipe has a length of about 20 cm.
- In another aspect of the present invention there is further provided a member formed of sound-absorbing material on a cylindrical surface of the outer tube.
- The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
-
FIG. 1 is a sectional view of a preferred embodiment of tailpipe of automotive vehicle according to the invention; -
FIG. 2 is a front view of the tailpipe; -
FIG. 3 is a rear view of the tailpipe; -
FIG. 4 is a perspective view of the tailpipe; and -
FIG. 5 is a view similar toFIG. 1 for illustrating a stream of exhaust through the tailpipe. - Referring to FIGS. 1 to 4, there is shown a tailpipe of an automotive vehicle constructed in accordance with the invention. The tailpipe comprises a
front tube 1, anouter tube 2, arear tube 3, and a plurality oftwisted blades 4. Each component will be described in detail below. - The
front tube 1 comprises afront section 10, acoupling 11 at thefront section 10, thecoupling 11 having a plurality of lengthwiseslits 111 and aring fastener 112 enclosed thecoupling 11 for flexibly compressing thecoupling 11 and fastening one end of a muffler S at thecoupling 11, a flaredrear section 13, and aneck 12 interconnected thefront section 10 and therear section 13, theneck 12 having a plurality of rows ofapertures 14 on its surface. - The
rear tube 3 comprises afront section 32 coupled to therear section 13, anintermediate section 31 having a diameter slightly smaller than that of thefront tube 1, and a flaredrear section 33. - A rear portion of the
front tube 1 and the wholerear tube 3 are surrounded by theouter tube 2. Theouter tube 2 is constructed by incorporating the principles of venturi tube. Theouter tube 2 comprises aflared front section 21, acylindrical section 20, an enlargedsection 22, arear section 24, and an inward extendingrim 23 at the opening of therear section 24. - The
blades 4 are equally spaced apart around theintermediate section 31 and are extended therefrom to fixedly couple to an inner surface of the enlargedsection 22. Theblade 4 comprises afront section 41 fixedly connected to therear section 13, a plurality ofapertures 42, and arear section 43 coupled to rear portions of theouter tube 2 and therear tube 3. - Referring to
FIG. 5 , stream of exhaust from an operating internal combustion engine to the tailpipe via an exhaust pipe will be described in detailed below. Stream of exhaust E enters into theneck 12 after leaving the muffler S. At theneck 12, pressure of the stream of exhaust E decreases in which a portion (i.e., stream component E1) of the stream of exhaust E flows into a space between theneck 12 and thecylindrical section 20 through theapertures 14. Stream component E1 is then mixed with air A drawn from thefront section 21. Also, pressure of the stream component E1 decreases. Another portion (i.e., stream component E2) of the stream of exhaust E flows out of therear section 13 into a space between theintermediate section 31 and the enlargedsection 22 to be baffled by theblades 4. After leaving theblades 4 by passing a plurality of channels each between twoadjacent blades 4 and theapertures 42, a whirlwind is formed. Still another portion (i.e., stream component E3) of the stream of exhaust E flows into therear tube 3. Also, pressure of stream component E3 decreases in therear tube 3. Thus, a stream component E4 is formed after leaving therear section 33. A whirlwind type of stream component E5 is formed by the mixture of stream component E4 and stream component E2. As an end, exhaust E0 is carried away by stream component E5. Note that the provision ofapertures - Preferably, the
outer tube 2 has a length of about 12 cm, thefront tube 1 has a length of about 12.5 cm, and the tailpipe has a length of about 20 cm less than prior art. Hence, the tailpipe can be readily mounted at the rear of muffler S of an automotive vehicle at thecoupling 11. Moreover, a sound-absorbing material can be formed around theouter tube 2 for further silencing noise. - It will be evident from the foregoing that the invention has the following advantages: High pressure exhaust from the muffler can be effectively driven out of the tailpipe by inducting air into the tailpipe to mix with stream of exhaust. As such, a more complete combustion of the engine is made possible. Further, pollutant contained in the exhaust can be effectively diluted by the induction or air. Hence, exhaust leaving the tailpipe is found to comply with even the strictest emission standard. Pressure of exhaust leaving the tailpipe is sufficiently lowered by the provision of a number of continuous enlarged and constricted stages of the tailpipe by incorporating the principles of venturi tube. This further facilitates the emission of exhaust.
- While the invention herein disclosed has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims.
