Figure 4 is a cross-sectional view showing another embodiment according to the present invention, exhaust emission reduction device for a motorcycle.

Hereinafter, with reference to the accompanying drawings an embodiment of the exhaust emission reduction device for a motorcycle according to the present invention will be described in detail.

In FIGS. 1 to 3, the smoke reduction device 1 is fixedly coupled with a coupling member 12 under the exhaust pipe 2 of a motorcycle. The coupling member 12 has an end portion fixedly coupled to the upper portion of the housing 11 while surrounding the outer circumferential surface of the exhaust pipe 2 in a metal strip shape. The coupling member 12 is coupled to one or more. Moreover, the exhaust pipe 2 is preferably fixed to the motorcycle body by a separate fixing means in order to fix and support the weight of the housing 11.

The housing 11 is a space having a certain volume formed therein, and a certain amount of liquid is stored and filled therein. The liquid contains alkaline water. The housing 11 is fixedly coupled to the lower portion of the exhaust pipe 2 of the motorcycle with a coupling member 12, but may be fixedly coupled to the upper or side surfaces of the exhaust pipe 2. In addition, a discharge hole 16 is formed at one side of the upper portion of the housing 11 so that gas with reduced soot is discharged from the inlet pipe 30 through the water inside the housing 11. In addition, an injection hole 14 and a stopper 15 for injecting a liquid are provided on one side of the upper portion of the housing 11. In addition, a discharge port 25 and a stopper 26 for discharging the liquid filled in the housing 11 are provided at one side of the lower end of the housing 11. When the liquid in the housing 11 evaporates or is insufficient, it is to fill through the inlet 14 from the outside after opening the cap 15 of the inlet 14. When the liquid filled in the housing 11 is contaminated, the outlet 25 It is for discharging to the outside through the outlet 25 after opening the stopper 26 of ). In addition, it is preferable that a transparent window 27 is provided on the side of the housing 11 so that the level of the liquid filled in the housing 11 can be easily known.

The inlet pipe 30 guides the gas discharged from the exhaust pipe 2 into the interior of the housing 11 and has a substantially tubular shape. The upper inlet of the inlet pipe 30 is fixed to the outlet of the exhaust pipe 2 with a fixing means 31. A plurality of through holes 32 are formed through the lower outer circumferential surface of the inlet pipe 30 to discharge the introduced exhaust gas. Further, the lower portion of the inlet pipe 30 is inserted and fixed into the housing 11 so that the exhaust gas discharged from the exhaust pipe 2 flows into the housing 11. In addition, a backflow prevention damper 33 is installed in the inlet pipe 30. The backflow prevention damper 33 blocks the gas discharged from the exhaust pipe 2 from flowing into the inlet pipe 30, but the liquid from the housing 11 flows into the exhaust pipe 2. This is to prevent the liquid in the housing 11 from flowing into the exhaust pipe 2 through the inlet pipe 30 when the motorcycle falls. Also, the outlet of the inlet pipe 30 is preferably bent toward the center of the housing 11. Furthermore, in the cross-sectional view of FIG. 4, the lower portion of the inlet pipe 30 may be extended to the inner center of the housing 11 and installed. This allows air bubbles containing gas discharged through the outlet of the inlet pipe 30 and the through hole 32 to be discharged from the inner center of the housing 11 so that the discharged gas can be dissolved in the liquid and purified faster and faster. I will be able to do it.

The first blocking member 17 is installed inside the upper portion of the housing 11 so that a plurality of first through holes 18 are formed at regular intervals. The first blocking member 17 prevents the liquid inside the housing 11 from being pulled or flowing to one side when the motorcycle starts or stops. In addition, a wedge-shaped first protrusion 19 protrudes downward at an edge of the first through hole 18. When the gas discharged from the inlet pipe 30 rises in the form of a bubble, the first protrusion 19 bursts the gas so that the gas is easily mixed with the liquid.

The second blocking member 20 is installed on the first blocking member 17 at regular intervals. The second blocking member 20 is formed in the shape of a curved plate that continues to the left and right, and a plurality of second through holes 21 are formed through the surface at predetermined intervals. The curved surface of the second blocking member 20 is to minimize the flow of the liquid filled in the housing 11.

The third blocking member 22 is installed on the second blocking member 20 at regular intervals. A plurality of third through holes 23 are formed in the third blocking member 22 at regular intervals. The third blocking member 22 is also for minimizing the flow of the liquid filled in the housing 11.

In addition, a plurality of second protrusions 24 are formed protruding downward on the inner ceiling surface of the housing 11 to burst fine bubbles rising through the third through hole 23 of the third blocking member 22 to release the exhaust gas. Mix with the liquid.

In addition, a dome 13 having a distribution structure is protruded on the inner bottom surface of the housing 11. The dome 13 prevents the liquid filled in the housing 11 from being thrown back and forth at a time when the motorcycle suddenly starts or stops.

The operation of the smoke reduction device for a motorcycle according to the present invention will be described.

First, a small amount of a neutral agent and Effective Microorganisms (EM) may be mixed with an appropriate amount of liquid, such as water, in the housing 11. Then, when the engine of the motorcycle is started and gas is discharged through the exhaust pipe 2, the gas is discharged to the outlet of the inlet pipe 30 through the backflow prevention damper 33 installed in the inlet pipe 30. At this time, the gas will also be discharged through the through hole 32 formed under the inlet pipe 30. The gas discharged from the outlet of the inlet pipe 30 and the through hole 32 is discharged in the form of bubbles in the liquid. At this time, as the gas bubbles are mixed with the liquid, various pollutants and fine dust are mixed with the liquid.

When the gas discharged from the inlet pipe 30 floats above the liquid, a wedge-shaped first protrusion 19 protruding in a crown shape at the edge of the first through hole 18 of the first blocking member 17 bursts the air bubbles. Let the gas mix with the liquid. In addition, when the bubbles burst through the first through hole 18 of the first blocking member 17 become smaller bubbles and rise, the bubbles are removed by the second blocking member 20 and the third blocking member 22. The gas and the liquid are more mixed. In addition, air bubbles can be almost completely removed by the second protrusion 24 installed on the inner ceiling surface of the housing 11.

In addition, the dome 13 installed on the bottom surface of the housing 11 minimizes the flow of the liquid so that the liquid filled in the housing 11 does not flow when the motorcycle is started, running or stopped, and the first blocking member (17), the flow of the liquid surface is controlled by the second blocking member 20 and the third blocking member 22 so that the liquid does not fluctuate. Moreover, the flow of the liquid surface is minimized by the curved second blocking member 20.

Therefore, the gas discharged through the exhaust pipe 2 is discharged into the housing 11 through the inlet pipe 30, and the gas flowing into the housing 11 is mixed with liquid to filter pollutants and fine dust. And only purified air is discharged through the discharge hole 16. In addition, water filled in the housing 11 can be minimized by the dome 13 and the installation structure of the first blocking member 17 to the third blocking member 22.

In the above description, the present invention has been illustrated and described in connection with specific embodiments, but it is understood that various modifications and changes are possible within the scope of the spirit and scope of the invention indicated by the claims. Anyone who has it will be easy to know.
