Description

Muffler for automobile {muffler for automobile}

The present invention relates to a muffler for automobiles, and more particularly, to convert to a constant pressure state by a cyclone method using a rotational force of centrifugal force inside a muffler that purifies exhaust gas generated when fuel is ignited in an engine of a vehicle and releases it into the atmosphere. The present invention relates to a muffler that is an exhaust gas purifying apparatus capable of purifying unpurified exhaust gas while changing the inner power configuration by shifting a diaphragm at a rear of the non-powered fan and passing through the non-powered fan.

In general, lowering the temperature and pressure of the exhaust gas discharged from the engine to reduce the exhaust noise is commonly referred to as MAIN MUFFLER, MAIN MUFFLER is a variety of types depending on the structure formed However, the steel plate of about 1mm is made into a cylindrical shape, and the inside is divided into several spaces, and when the exhaust gas passes through their barriers, it causes noise interference, decreases in pressure fluctuations, and decreases in exhaust temperature. As shown in FIG. 7, a through hole 114 is formed in the inner central portion so as to penetrate back and forth, and the inner diameter of the through hole 114 is smaller than the other inner diameter. 116 is formed of a sound absorbing material 112 that is integrally provided, and when the exhaust gas passes through the through hole 114, interference of sound waves and pressure fluctuations. In addition to reducing the copper and lowering the exhaust temperature, it is possible to gradually generate noise, as well as to increase the flow rate when the exhaust gas passes through the concave diameter portion 116 formed in the through hole 114, the frequency of the pressure wave It is configured to change the absorption to remove.

However, in the case of the main muffler 110 described in the latter of the main mufflers, as described above, the through hole 114 having the recessed diameter portion 116 smaller than the inner diameter is formed integrally with the inner muffler. Since the structure is made of a sound absorbing material 112, the structure is very simple and does not achieve an effective noise, the problem phenomenon that greatly reduces the quietness of the inside of the vehicle during driving, and there is also a problem that significantly reduces the ride comfort, accordingly, In addition, there is a problem that can not effectively respond to the legal regulation of the emission noise, and as a result, the added value of the entire vehicle produced by using such a conventional technology to reduce the merchandise and quality of the vehicle, as well as, Problems have occurred such as greatly lowering the reliability of the user.

The present invention has been made in order to solve such a conventional problem, while turning the exhaust gas of the car introduced into the muffler through the inlet to turn down from the inside of the muffler to the outer circumferential side, but gradually decreases the turning lowering force and eventually the critical In the position, it is converted into a constant pressure state so that dust separation of the exhaust gas can be efficiently carried out, and after the first purification as described above, it passes through a diaphragm mounted to allow the exhaust gas to flow zigzagly inside the muffler. Its purpose is to completely remove dust and remove harmful substances such as sulfurous acid gas, carbon monoxide, NOx and SOx.

In order to achieve the above object, an inlet port is connected to the engine and the exhaust gas burned in the engine is introduced into the muffler, and an exhaust port is mounted on the opposite side of the muffler equipped with the inlet port, and exhaust gas passing through the muffler is atmosphere. There is a typical automotive muffler composed of exhaust vents released into the vehicle;

The first end is connected to the inlet so that one end is fixed to the muffler wall surface on the side of the inner side of the muffler and the side of the muffler coupled to the side of the muffler, and the vent is formed to allow the exhaust gas to pass through the side of the muffler coupled to the inlet.

Figure 6 shows another embodiment of the muffler of the present invention.

One end portion is fixed to the muffler 52 wall surface on the side where the left and right wall surfaces of the muffler 52 and the exhaust gas exhaust port 12 are coupled to the inner center of the muffler 52, and the exhaust gas inlet 10 is coupled to the muffler 52. The first device 60 connected to the exhaust gas inlet 10 and the second device 62 connected to the exhaust gas exhaust port 12 are formed so that the vent hole 54 is formed at the side surface 52 of the exhaust gas passage. With the middle diaphragm 34 to separate,

The first, second, and third non-power 의 of the rhombus shape in which the blades 14 are attached in the same direction as the exhaust gas flowing into the upper and lower portions inside the first device 60 to which the exhaust gas inlet 10 is connected. (44) (46) (48) First and second control panels (26) (28) having a plurality of return holes (50) formed at the center and rear vents (32) formed at four sides of the outer circumferential surface, respectively. 30 is coupled to the bearing 24, the shaft 18 is coupled to the circular cylinder equipped with a shaft 20 is coupled to the rotational movement and the support shaft 22 for supporting the shaft 20 in the center ( 36) and,

The upper diaphragm 38 and the lower diaphragm 40 are staggered so that the inner diaphragm 34 and the inner wall of the muffler 52 are fixed to the inner wall of the second device 62 connected to the exhaust gas outlet 12. To do that,

The exhaust gas inlet 10 and the exhaust gas exhaust port 12 are directly connected by a circular cylinder 36, and a plurality of non-power fans are connected to purify the exhaust gas.

The operation of the present invention is as follows.

One end of the muffler 52 is fixed to the inner wall of the muffler 52 at the side where the left and right side walls of the muffler 52 and the exhaust gas exhaust port 12 are coupled to each other, and the exhaust gas inlet 10 is coupled thereto. The first device 60 connected to the exhaust gas inlet 10 and the second device 62 connected to the exhaust gas exhaust port 12 so that the vent hole 54 is formed on the inner side of the muffler 10 to allow the exhaust gas to pass therethrough. Attach the middle diaphragm 34 to separate).

When the exhaust gas is introduced through the exhaust gas inlet 10 to the inside of the first device 60 to which the exhaust gas inlet 10 into which the exhaust gas of the fuel ignited in the engine flows is connected, Rhombus shape in the direction (right) to which the blade 14 of the first non-power 휀 44 of the rhombus shape is most closely mounted inside the circular cylinder 36 coupled with the exhaust gas inlet 10 by the wind direction. The first non-power 휀 44 is rotated (to the right), which causes the exhaust gas to be pushed to the wall surface of the circular cylinder 36 by the centrifugal force of the blade 14.

That is, since only the outer periphery in the circular cylinder 36 rotates by the centrifugal rotational force of the rhombus-shaped 1st non-power 휀 44 rotated by the input / output of exhaust gas, the 1st non-power 휀 44 of a rhombus shape is comprised. In the center of the blade fixing plate 16 to which the blade 14 is coupled is to form a pressure-free zone.

Due to the centrifugal force generated by the rotation of the blade 14, the exhaust gas has an expansion force in and around the circular cylinder 36, and this expansion force is inevitably turned due to the centrifugal force of the first non-motor 휀 44 having a rhombus shape. Will have.

The exhaust gas pushed out to the wall surface of the circular cylinder 36 as described above is the first control panel 26 and the circular cylinder (fixed to the shaft 18 coupled to the bearing by the rear of the first non-power 휀 44 of the rhombus shape) 36) is discharged to the rear through the vent 32 formed in all directions between.

When the first non-power 휀 44 of the rhombus shape is rotated in the right direction, the second non-power 휀 46 of the rhombus shape is rotated to the left in reverse, and the first non-power 휀 44 and the first shape of the rhombus shape is rotated to the left. The rotation is caused by the pressure and the wind direction of the exhaust gas passing through the control panel 26.

When the second non-power 휀 46 of the rhombus shape rotates, the exhaust gas is pushed out to the wall surface of the circular cylinder 36 again and formed between the second control panel 28 of the rhombus shape and the circular cylinder 36 ( 32) it will be discharged backwards.

As described above, the exhaust gas has passed through the first non-power 휀 44 having a rhombus shape and the second non-power 휀 46 having a rhombus shape that rotates to the left opposite to the traveling direction, and the vent 32 formed in the second control panel 46. The gas flows into the third non-power 휀 48 of the rhombus shape, and the third non-power 휀 48 of the rhombus shape rotates to the right in reverse to the second non-power 휀 46 of the rhombus shape. The third non-power 휀 48 having a rhombus shape is rotated due to the air volume of the exhaust gas passing through the vent 32 formed in the third control panel 30 and the second non-power 휀 46 having a rhombus shape. Will be done.

Therefore, since the exhaust gas discharged from the engine flows in through the exhaust gas inlet 10, the rotational speed of the first non-motor 휀 44 having a rhombus shape mounted closest to the exhaust gas inlet 10 is the highest. Next, the rotational speeds of the rhombic second non-power 력 46 and the rhombic third non-power 휀 48 are the slowest.

As described above, the first, second, and third non-power shaps 44, 46 and 48 of the rhombus shape forming the first device 60 and the first, the first, third and third powerless shabs 44 and 46 of the rhombus shape are provided. Exhaust gas passing through the vent hole 32 formed between the first, second, and third control panels 26, 28, 30 of the rhombus shape, and the circular cylinder 36 mounted on the rear of the cylinder 48 is wind pressure and air volume, And the exhaust gas exiting the circular cylinder 36 in a constant pressure state with zero wind speed, and the exhaust gas exiting the circular cylinder 36 is synergistically moved through the pressure-free zone and flows into the natural flow along the outer wall of the circular cylinder 36. The second device 62 through the air vent 54 of the intermediate diaphragm 34 is formed in the middle of the muffler 52 and the air vent 54 is formed while separating the first device 60 and the second device 62. It will become a flow.

That is, the exhaust gas flowing through the exhaust gas inlet 10 passes through the first, second, and third non-power 44 44, 46, 48 of the rhombus shape, and the first, second, and third non-power 휀 of the rhombus shape. The rotation of the (44), (46), (48) causes the exhaust gas to rotate along the inner circumferential surface of the circular cylinder (36), whereby contaminants such as dust are dispersed and decomposed.

If the driver suddenly presses the accelerator pedal during operation, the exhaust gas is introduced into the muffler 52 through the exhaust gas inlet 10 at once, so that a large amount of the exhaust gas flows into the muffler 52 at once. When the first non-power 휀 44 of the rhombus shape is rapidly rotated and is pushed to the inner wall of the exhaust gas circular cylinder 36 to descend to the second non-power 휀 46 of the rhombus shape through the vent 32. 2 The non-power 휀 46 rotates considerably slower than the first non-power 휀 44 having a rhombus shape so that a part of the exhaust gas is formed through a vent 32 formed on the outer circumferential surface of the second control panel 46. The exhaust gas, which is lowered to the third non-power 휀 48 of the exhaust gas but does not escape, is raised toward the first non-power 휀 44 of the rhombus shape through the return port 50 formed in the first control panel 26. Is purified again will be dropping into the second non-powered fan (46) of the rhombic shape.

The above operation is repeatedly performed between the second non-power 휀 46 of the rhombus shape and the third non-power 휀 48 of the rhombus shape so that the purification can be easily performed even when the exhaust gas is introduced at once.

Since the non-power fan (44) (46) (48) was installed with the horizontal width gradually widened upward, the turning lowering force of the exhaust gas is the control panel (26) (28) (30) of the first, second, and third. And gradually become weakened, and thus, when reaching the third control panel, the exhaust gas almost loses the turning lowering force.

The exhaust gas filtered while passing through the first device 60 is introduced into the second device 62 as described above. The second device 62 is connected to the exhaust gas exhaust port 12 and has an intermediate diaphragm 34 therein. The inner wall of the muffler 52 and the upper plate 38 and the lower plate 40 are staggeredly coupled to each other to have a predetermined interval to pass through the zigzag.

The upper diaphragm 38 is arranged on the muffler 52 wall and the lower diaphragm 40 is alternately arranged to have a bending path in the middle diaphragm 34 to form a plurality of cataclysmic exhaust gas flow charts 42. The number of the 38 and the lower diaphragm 40 and the number of the rhombus-shaped non-motors 되는 mounted to the first device 60 can also be increased or decreased depending on the necessity and capacity.

Since the exhaust gas passing through the second device 62 always maintains a constant pressure state, since the exhaust gas does not have a forced flow force, the exhaust gas is inevitably guided to the upper plate 38 and the lower plate 40 in a zigzag manner. You will be guided.

Therefore, fine dusts not separated in the first device 60 are completely separated in each bending path, and the exhaust gas, which is harmless to the human body, is released into the atmosphere through the exhaust port.

The blade fixing plate 16 integrally coupled with the shaft 18 is supported by the shaft 20 to rotate. The first, second and third control panels 26, 28 and 30 rotate by a bearing. It will be able to be fixed fixed.

In addition, as another embodiment of the present invention, as shown in Figure 6, when the displacement of the vehicle is large, the intermediate plate 34 separated by mounting one more middle diaphragm 34 in the interior of the muffler 52 and In the space between the intermediate plates 34, there is a circular cylinder 36 which is provided with non-power fans 44, 46, 48 and control panels 26, 28, 30 in the same direction as the flow of exhaust gas. In addition, in the above embodiment of the present invention, the upper diaphragm 38 and the lower diaphragm are staggered so as to have regular intervals on the inner walls of the middle diaphragm 34 and the muffler 52, respectively. (40), the fine particles were not separated from the circular cylinder 36, which was provided with the non-power wheels 44, 46, 48 and the control panels 26, 28, and 30, When the exhaust volume of the vehicle is small, both the middle partition, the upper diaphragm 38 and the lower diaphragm 40 are not provided in the muffler. A circular cylinder 36 connected to the exhaust gas 10 inlet and the exhaust gas exhaust port 12, and mounted in the circular cylinder 36 and having a blade 14 attached in the same direction as the exhaust gas flow. A plurality of ripple-shaped non-powered fins 44, 46, 48, and a plurality of return holes 50 are formed in the center, and a plurality of control panels 26, 28 formed with vent holes 32 on all sides of the outer circumference. The circular cylinder 36 equipped with the bearing 20 in which the shaft 18 in which 30 is coupled with the bearing 24 becomes a rotational movement, and the support interval 22 which supports the bearing 20 in the center. ) Can be sufficiently purified even if the exhaust gas is mounted inside the muffler 52.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

Therefore, the present invention is only configured to turn down the exhaust gas to the outside of the circular cylinder by the centrifugal rotational force of a plurality of non-power 휀, and the turning down force is weakened and returned by the control panel at this time, Even if the input or output of exhaust gas is strong or weak, the effect of perfect dust separation can be made smoothly without regard to it, and the dust separated exhaust gas is naturally raised in the circular cylinder of the pressureless zone, In addition to maintaining the state, the exhaust gas flowing into the second device is always kept at a constant pressure so that the bend path of each catastrophic flow chart can completely remove and remove all fine residual dust that has not been separated from the first device. Compared to the muffler which has the effect and is attached to a conventional car to clean exhaust gas In addition to lowering the gas pressure, minimizing noise, and reducing engine incubation, fuel savings and the temperature of exhaust gases emitted from automobiles can be lowered. It is a very beneficial invention.
