Description

Wing structure of air swirling device for internal combustion engine}

The present invention relates to a wing of an internal combustion engine intake and exhaust device rotating device, and in particular, to induce the rotational action of the filtered air passing through the air cleaner in the carburettor type or fuel injection type electric ignition internal combustion engine, diesel engine, etc. to be introduced into the combustion chamber of the engine. The blade shape of the rotating device is adapted to reduce the negative pressure (or negative pressure) and the resistance caused by the vortex.

By applying rotational force to the flow of air sucked into the combustion chamber of the internal combustion engine to increase the moving speed per unit time, supplying a large amount of air at high density to the combustion chamber of the engine to improve the combustion action of the internal combustion engine to improve the output of the engine Many rotary devices or means similar to the rotary device have been proposed, and this conventional technique has a drawback in that it is not possible to completely prevent the relative air resistance that is formed when the fluid is rotated.

For example, a rotary apparatus including an intake valve having a large intake resistance of Japanese Patent Publication Nos. 53-26247, 59-11722 and US Pat. No. 4,309,969 has a turbulence apparatus that generates only turbulence without uniformly generating fluid rotation. Is proposed.

In addition, Japanese Patent Publications No. 60-17922, 61-10645, and U.S. Patent Nos. 4,434,777, 4,432,312, 4,539,954 have rotation generators for rotating air by installing a wing in close proximity to an intake valve of an internal combustion engine. It is proposed.

However, these devices have been limited to use in carburetor-type gasoline engines because of the reduced amount of air drawn in by high friction.

In order to solve the above problems, U.S. Patent No. 4,962,642 installs an air rotating device having a plurality of vanes in an air cleaner to turn intake air into the combustion chamber to improve combustion performance and engine output. Pneumatic rotating device is presented. However, in the air rotating device for internal combustion engines, eddy, which is a vortex phenomenon, is generated in the rear (negative pressure region) of the wing during the flow of air, so that the engine output decreases due to the decrease in the amount of inhaled air, and the loss of fuel, etc. Is holding.

On the other hand, the technique of the Republic of Korea's pre-registered utility model registration No. 77786, as shown in Figs. 1 and 2, the internal combustion engine intake and exhaust rotator main body 10, and one or more slender slits (long) in the main body 10 ( It is configured by mounting a plurality of wings 11 having a 12, the rotating body main body 10 is fixedly installed by bolts and nuts in close proximity to the center of the air cleaner 13 to turn the suction air, In the negative pressure region and the negative pressure region formed on the back of the blade 11, the vortices generated by the air inflow are exhausted through the slits 12 to prevent vortex generation, thereby reducing the fluid resistance and increasing the amount of fluid, thereby improving energy efficiency. And for the purpose of improving output power.

As described above, the rotary device having the slits 12 in the blade 11 applies rotational force to the flow of air sucked into the combustion chamber 14 as shown in FIG. 1 to increase the moving speed of the air per unit time and to increase the density of combustion. A plurality of blades of the rotary body main body 10, in which the air filtered from the air cleaner 13 is sucked by the slits 12 formed on the blades 11 and is sucked into the internal combustion engine by the slits 12 formed on the blades 11. The swinging fluid is pivoted via the slits 12 formed in the (11), and the swirling fluid is rotated again by the other rotating device 16 provided near the inlet of the intake manifold 15 and supplied to the combustion chamber 14 at high speed. . The combusted exhaust gas is quickly discharged by another rotary device 18 installed near the inlet of the exhaust manifold 17.

The intake / exhaust rotation device of the internal combustion engine forms the at least one slits 12 in the plurality of blades 11, thereby reducing the generation of vortices in the negative pressure region on the rear surface of the blades 11. When such a rotary device is applied to the air cleaner 13, carbon monoxide decreases by about 17% in engine idle speed, output is increased by about 11%, fuel economy is improved by about 6%, engine knocking phenomenon. It was also shown to decrease by about 5%.

Accordingly, the intake / exhaust rotation apparatus of the internal combustion engine having the slits 12 on the blades 11 applies rotational force to the flow of air sucked into the combustion chamber to increase the moving speed of the air per unit time and increase the density to improve the combustion action. The slitting 12 formed on the blade 11 prevents vortex generation in the negative pressure region and decreases the resistance of the fluid, thereby increasing the flow rate, thereby supplying a sufficient amount of accelerated air to the engine to achieve combustion efficiency and It can be seen that it is promoting the increase in output.

However, the conventional intake / exhaust rotation apparatus of the internal combustion engine having the slits 12 on the blades 11 has a shape in which a portion of the flat blades 11 is cut in a long and thin shape to form a gap, thereby reducing the vortex. Such thin slits 12 are difficult to see necessarily producing ideal results and in some cases could not cope with the need for more controlled flow of air.

For example, the intake / exhaust rotation device having the slits 12 on the blades 11 applies rotational force to the flow of air sucked into the combustion chamber to increase the speed of movement of air per unit time, increase the density, and further output the combustion. There are features to help improve, but it is not enough to control the flow of air with just one rotary unit.

That is, the slender 12 in the elongated direction discharges the vortices formed in the negative pressure region on the rear side of the blade 12 to reduce the fluid resistance, but the slits 12 are directly cut out on the surface of the blade 11. In the process of discharging the vortices formed in the negative pressure region, the collision of the vortices with respect to the entire area of the wing may appear, and at the same time, the slight reverse flow of the vortices may also appear around the slits 12.

In addition, when cutting the slender long rectangular slits 12 into the blades 11, the possibility of deformation of the blades 11 also appears larger than that of the hole shape. Deformation of the wing reduces air flow.

In addition, the shape of the wing body for forming the slits 12 on the wing 11 to suppress the formation of vortices in the negative pressure region has a top side and a bottom side in a plane to induce the flow of air linearly, so that the fuel particle side And may be disadvantageous in maintaining stable mixing uniformity.

Therefore, the purpose of the present invention is to apply a rotational force to the flow of air sucked into the combustion chamber of the internal combustion engine to increase the speed of movement of air per unit time and increase the density, so that the new intake and exhaust rotation is mounted on the air cleaner for the purpose of improving the combustion and output of the engine. To provide the wings of the device.

Another object of the present invention is to apply a rotational force to the flow of air sucked into the combustion chamber of the internal combustion engine to increase the speed of movement of air per unit time and increase the density, so that the internal combustion engine intake and exhaust ventilator installed in the air cleaner for the purpose of improving the combustion and output of the engine It is to provide a wing of the internal combustion engine intake and exhaust rotation device that can reduce the deformation of the wing of the rotating device.

In addition, the periphery of the fluid flow hole 40 is provided with a guard 50 protruding at an appropriate protruding length.

Reference numeral 21 is a plate-shaped protrusion formed on the wing. 31 is a through groove formed on the main body side of the rotating apparatus, and the vane 20 is assembled on the main body of the rotating apparatus by sandwiching the protruding portion 21 of the wing 20.

In addition, as shown in FIG. 5, each side of the upper side 23 and the lower side 24 of the wing 20 may include a wave surface 25 for inducing the flow of the fluid into nonlinearity to promote mixing with the fuel particles. have.

In order to reduce the flow resistance of the fluid due to the vortex formed in the negative pressure region of the blade 20, at least one fluid flow hole 40 formed at any position of the blade 20 is a porous through hole is suitable.

The guard 50 formed in the peripheral negative pressure region of the fluid flow hole 40 forms a wall at a part of the outer portion of the fluid flow hole 40 as shown in FIG. 6 (a) (b) (c) (a). ), Or (b) in which the entire outer region of the fluid flow hole 40 is formed by the guard 50, and the shape of the guard 50 is arranged to be alternately arranged or partially formed. (C) can be selectively applied to create a wall around).

The arrangement and arrangement of the fluid flow hole 40 and the guard 50 forming a wall at the edge of the fluid flow hole 40 may be selected and applied in the following arrangement example or in a similar manner. Can be. Here, it is assumed that the arbitrary guard 50 is installed in the fluid flow hole (40).

7 (a) (b) (c) (d), one fluid flow hole 40 is arranged along the surface 22 of the wing 20 and evenly arranged and arranged in a row. Rule array (a),

A large diameter independent arrangement (b) in which the fluid flow hole 40 is formed along the surface 22 of the wing 20 and the fluid flow space is expanded with its position approximately at the center;

In forming the fluid flow hole 40 along the surface 22 of the blade 20, multiple arrays d and the like that are evenly arranged on the entire surface of the blade without considering the arrangement position may be applied as an array structure.

In addition, as shown in FIG. 8, the wave surface 25 formed on the side portion which nonlinearly induces the flow of fluid in each of the upper side 23 and the lower side 24 of the wing 20 has an upper side 23 or a lower side ( 24) may be selectively formed, and may have a streamlined wave face (a) or a sawtooth wave face (b) as shown in the figure, and may be formed in a suitable plane in consideration of other fluid flow characteristics. .

The wing 20 of the intake and exhaust rotation apparatus for an internal combustion engine according to the present invention having various fluid flow holes 40, the guard 50, and the wave surface 25, can be obtained through the wing of the existing intake and exhaust rotation apparatus. It retains its functional characteristics. In other words, the main function of providing the rotational force to the flow of air sucked into the combustion chamber of the internal combustion engine to increase the moving speed of the air per unit time and increase the density to realize the combustion and output of the engine is maintained as before.

The fluid flow hole 40 according to the present invention takes the form of porous large and small diversified holes, but the optimal combustion and output performance cannot be obtained only by selecting the arrangement shape of the holes. This is dependent on the engine side condition, can be described with respect to the combustion and output improvement of the engine only by the difference in shape between the cut-out slits 12 or the fluid flow hole 40 of the present invention mentioned in the prior art. none.

However, in the case of applying the fluid flow hole 40 and the guard 50 to prevent the vortex in the negative pressure region of the blade 20, a more deliberate design is possible. In other words, according to the engine conditions, the shape and size of the fluid flow hole 40 and the guard 50 may be determined more intentionally, so that the design of a rotating device suitable for the engine may be possible. As such, it is possible to design various rotating devices suitable for the conditions of the engine.

In addition, the fluid flow hole 40 has the advantage that it can be press-processed in various arrangements and sizes in the area of the relatively narrow blade 20 freely of large and small diameter hole size, the guard formed on the outside of the fluid flow hole 40 If 50 is not required to be formed at such a large height, it is possible to form the guard 50 in the press batch process. Otherwise, the guard 50 must be separately mounted in the same manner as welding.

The hole size of the fluid flow hole 40 is the hole size of the fluid flow hole 40 in view of the fact that the outer rotation is large and small toward the inside due to the rotational characteristics of the blade 20, the vortex is also large in the outer side and less in the center It is better to increase the outer side and gradually decrease it toward the center.

In the case of forming a circular fluid flow hole 40 instead of a cutout surface (slit) on a thin thin plate-like wing 20, there is no distortion, and thus a bearing strength is given to itself, and deformation before and after pressing is a rectangular groove. Less than

The guard 50 formed at the periphery of the fluid flow hole 40 protrudes in the negative pressure region so that the collision of the vortices formed in the negative pressure region of the blade is not distributed over the entire surface of the blade, thereby stably rotating the blade 20. It maintains the castle, and also prevents the phenomenon that the fluid (vortex) flowing into the guard 50 is backflowed to the negative pressure region.

On the other hand, when the wave surface 25 is formed along the longitudinal direction of the other side, that is, the upper side 23 and the lower side 24 except for the side directly contacting the main body 30 when mounted on the rotary device main body 30 When the 20 rotates, the air that hits the outermost portion of the wing 20 may be changed by changing the air flow in the nonlinear wave waveforms W1 and W2 as shown in FIG. 9.

When the edge of the wing has nonlinearity, it can help in mixing by indirect stirring effect when mixing with fuel particles corresponding to other fluids, and improve the mixing state of air and fuel particles, and increase the air intake amount by increasing the wing surface area. Increase, change the fast entry angle, and strengthen the straightness.

As such, the present invention can change the structure and shape of the blade configured in the internal combustion engine intake and exhaust device rotating device without the need for separate parts, thereby providing various rotating devices for various engines through the diversification of the blade shape of the existing rotating device. It is effective, and it is possible to prepare for deformation without degrading the workability of the vortex prevention means, which is necessarily formed on the face of the wing, and to reduce the vortex collision and backflow in the negative pressure region of the wing, and to change the shape of the edge of the wing. By inducing a flow change of the air flow there is an effect that can improve the performance of the rotary apparatus used for the purpose of improving the combustion and output of the internal combustion engine as a whole.
