Abstract
In general, a muffler structure of an internal-combustion engine includes a plurality of plates having a plurality of holes in a cylinder-shaped tube having a larger volume of exhaust gas generated by an explosion in the internal combustion engine. The plate is partitioned into tubes.
Therefore, it is possible to reduce the noise generated in the internal combustion engine by expanding the compressed exhaust gas through such a structure and reducing the pressure and air amplitude of the sound transmission medium while passing through the small holes. However, there is a limit to the noise reduction that can be achieved in this structure.
On the other hand, the present invention, in the general structure applied to the internal combustion engine, by rotating and irregular (eddy, turbulent flow) flow of the exhaust gas that delivers the explosion sound after the explosion to reduce the pressure and amplitude of the exhaust gas more effectively It should have a silencer (exhaust pipe) structure to make it possible.
Description
The present invention relates to a muffler / tube structure used for an internal combustion engine, and more particularly, to have a muffler structure applied to an exhaust pipe for discharging exhaust gas that emits an explosive sound to have a more efficient structure for transmitting an explosion sound. TECHNICAL FIELD [0001] The present invention relates to a silencer / exhaust pipe structure technology that rotates and irregularizes exhaust gas to have an effective noise effect.
The silencer structure for internal combustion engines of the prior art is for plates or partitions having a plurality of holes in a cylinder tube having a large diameter (diameter) in order to reduce the pressure and sound amplitude of the exhaust gas emitted after the explosion. By using a baffle or the like, as shown in Figs. 4 and 5, the inside of the pipe is generally divided into several parts, thereby reducing the pressure and amplitude of the sound transmitted through the exhaust gas, thereby reducing the explosion noise. To achieve the structure.
The silencer structure for internal combustion engines of the prior art uses a tube-shaped silencer (exhaust pipe) having a large diameter and a long length in order to reduce the explosion sound (sound) through the emitted exhaust gas.
Moreover, in order to reduce the sound as much as possible, the larger and kinder muffler is used, the greater the effect.
However, there are space limitations to using this type of silencer.
In addition, there are limitations in reducing the explosion sound only with a plate or baffle having several holes.
In particular, when the silencer is attached to an exposed internal combustion engine such as a motorcycle, there is a problem in that the size of the silencer itself is limited.
The present invention can make the structure of the muffler (muffler) according to the prior art more effective to reduce the explosion sound delivered through the exhaust gas more effectively.
The present invention is to change the flow of the exhaust gas (medium, air) passing through the internal structure of the silencer (exhaust pipe) to minimize the explosion sound (sound, noise);
-Explosion noise (noise) can be reduced more than the structure consisting of a plate with a plurality of holes or a baffle for partitions,
Relatively reduce the size of the silencer (exhaust pipe),
-More effective exhaust gas,
-Exhaust gas can make a good sound (sound).

2 is another structural diagram of silencer / exhaust pipe.
(Figure 3) is """"".
Figure 4 is a structural diagram of a silencer / exhaust pipe according to the example of the prior art.
5 is another structural diagram of silencer / exhaust pipe.
A silencer (exhaust pipe) is used by using a pinwheel / windmill or propeller-type unit that can rotate or eddy or turbulence flow the exhaust gas flowing through the muffler. Place the required number of units in the proper location inside. At this time, the size and position of the object is adapted to the shape and size of the silencer (tube) to be applied. In addition, it is possible to reduce the explosion sound more effectively by using a plate having a plurality of holes conventionally used, a baffle or other type of structure for controlling the flow of exhaust gas.
That is, as shown in Fig. 1, Fig. 2, and Fig. 3;
