Description

Vortex generating member for exhaust gas exhaust

The present invention relates to a vortex generating member for exhaust gas discharge installed in an exhaust pipe of a vehicle, and more particularly, it is possible to discharge the exhaust gas burned from the engine more quickly in the exhaust pipe, and also through the fire remaining in the engine. The present invention relates to a vortex generating member for exhaust gas discharge that reduces combustion gas and increases engine output.

In general, an exhaust structure installed in a conventional vehicle is a structure in which a catalyst device, a sub muffler, and a main muffler are connected to an exhaust pipe from an engine.

As a means for discharging the exhaust gas remaining in the engine of the vehicle and increasing the output of the engine in the connected exhaust structure, a screw is installed inside the sub-muffler to exhaust the exhaust gas from the engine more quickly. Since the exhaust pressure is reduced in the process of passing the exhaust gas between the sub-muffler and the main muffler through the exhaust pipe between the sub-muffler, there is a problem in that the exhaust gas generated from the engine cannot be efficiently discharged only by changing the structure of the sub-muffler.

As a prior art in this field, Korean Utility Model Registration No. 20-0324787 (Registration Date: Aug. 18, 2003), a catalytic converter is connected by an exhaust manifold and a connecting pipe of an engine, so as to communicate with the catalytic converter. In the muffler consisting of a main muffler and a sub muffler, the sub muffler has a concave groove-shaped coupling portion formed at both sides, and an end portion of which is bent in a fallopian tube shape to form a breakaway prevention jaw; A vortex generating member radially formed with four twisted pieces forming a screw; A flange having a coupling hole formed at a center thereof and having a long hole formed at both sides thereof, the flange being coupled to be positioned at a coupling portion of the body part; The muffler structure for automobiles is characterized in that the inner circumferential surface is bent in the form of a fallopian tube to one side, and is formed of a connecting socket having a protrusion.

In addition, Korean Patent No. 10-0404585 (Registration Date: October 24, 2003), which is a patent document, has a case body having a pipe shape at both sides, an insertion hole formed at the center thereof, and a heat insulating material inserted into the case body. A muffler comprising a pressure reducing member having a plurality of through holes on an outer circumferential surface, a cap having connectors provided at both sides of the case body, and a resonance portion formed at predetermined intervals between an inner surface of the hollow member and an outer surface of the pressure reducing member. In the muffler provided to discharge the exhaust gas into the atmosphere, the hollow member is fitted in close contact with the inner surface of the heat insulating material insertion hole inserted into the case body, and the vortex forming member inserted into the inner surface of the pressure reducing member Is installed with the same length as the pressure reducing member, and the upper and lower surfaces of the band-shaped plate are bent in a spiral shape to flow through the inner surface.

It can be seen that the efficiency is partially reduced.

In particular, the exhaust pipe connected between the sub-muffler and the main muffler is manufactured in various lengths and curved shapes according to the type and manufacturer of the vehicle, and all the companies are manufacturing the irregular pipe without forming the exhaust pipe in a straight line. Therefore, even if the exhaust gas is rotated like a whirlwind by a screw in the sub muffler and discharged quickly, the air exhaust rate is reduced by the bent portion and the length of the intermediate exhaust pipe, so the function of the sub muffler cannot be utilized at 100%. There was this.
