Description

Smoke reduction device for vehicle internal combustion engine {THE EXAUST FUMES REDUCTION DEVICE FOR INTERNAL COMBUSTION ENGINE OF SHIP}

The present invention relates to an exhaust gas reduction device for an internal combustion engine of a vehicle, and more particularly, by facilitating the exhaust flow of exhaust gas in a state additionally installed at the end of an exhaust line of a vehicle, it is possible to reduce the generation of soot, improve output, and improve fuel efficiency. It relates to an exhaust emission reduction device for an internal combustion engine of a vehicle.

In modern society, interest in the environment is quite high. Recently, as environmental problems caused by a series of fine dust have emerged, interest in air quality is increasing. In the case of automobiles and ships, internal combustion engines are used, so when the internal combustion engine is aged, exhaust gas contains a lot of soot, and thus it is being pointed out as a target that generates pollution and fine dust.

Therefore, research on exhaust noise and exhaust gas reduction in vehicle development is actively being conducted, and regulations for reducing greenhouse gas reduction and harmful factors are further strengthened.

On the other hand, a vehicle using an internal combustion engine obtains power by four cycles of suction, compression, explosion, and exhaust, as is well known. Looking at the flow of air (intake, exhaust) in the above strokes, in the suction process When passing through an air cleaner, throttle valve, etc., inflow occurs without relatively great resistance.

However, in the exhaust process, since it is discharged to the outside through an exhaust manifold, an air purifier using a catalyst, and a tailpipe (exhaust pipe) of the muffler, considerable resistance to the exhaust flow occurs.

In addition, in the process of being discharged from the cylinder of the internal combustion engine to the tail pipe of the silencer, in the exhaust manifold, the so-called valve overlap occurs in which the intake valve and the exhaust valve are momentarily opened simultaneously during the four strokes of the internal combustion engine. In addition, a phenomenon in which the gas discharged during this process is re-introduced into the cylinder occurs, and a vacuum state is instantaneously formed in the exhaust manifold, thereby forming a primary exhaust pressure that hinders exhaust gas discharge.

And, in the three-dimensional catalyst device, which is an air purifier, the flow velocity of the exhaust gas is significantly reduced while passing through the fine ventilation holes of the honeycomb-type exhaust gas purifier, thereby forming a secondary exhaust pressure. When it is absorbed around the partition, a tertiary exhaust pressure is formed.

Due to the resistance of the exhaust process, the combustion gas of the internal combustion engine cannot be discharged smoothly, and thus about 20 to 25% of the output is reduced. Accordingly, it is possible to improve the output of the internal combustion engine and improve the fuel economy simply by smoothly discharging the exhaust gas.

In order to somewhat solve these problems, in Korean Patent Application Laid-Open No. 10-2016-0118096, the vortex for an internal combustion engine has a first housing that communicates with the internal combustion engine, and is located inside the first housing and has a first center as the center.

It is formed of a second vortex part consisting of a second central passage part and a second fixed vortex fan which is located between the second housing and the second central passage part and connected to the second housing and the second central passage part. The rear surface of the second vortex part is coupled to the rear surface of the first vortex part, and the first fixed vortex fan formed in the first vortex part and the second fixed vortex fan formed in the second vortex part are alternately arranged and coupled to each other. The vortex for an internal combustion engine has a problem in that it is difficult to form a smooth vortex of the exhaust gas due to a pressure drop when exhaust gas is discharged because the structure of the vortex fan and the area occupied by the vortex fan and the central passage part are large.

Registered Patent No. 10-1952142 is a vortex generator equipped with a case to generate multiple tornadoes, and by installing an air vortex generator in internal combustion engines of automobiles, aircraft, ships, and various industrial machinery, the intake and exhaust air is converted into a vortex. The vortex generator capable of generating a multi-vortex wind that can induce the flow of the air at high speed to increase the intake and exhaust efficiency, the body and the body formed in the direction of the air flow inside the intake pipe so that the air sucked into the internal combustion engine forms a vortex. As a vortex generator formed of a plurality of wings coupled to the outer circumferential surface of the negative, the body is a hollow cylindrical or hollow polygonal column, and a coupling groove of a plurality of long holes is formed in the longitudinal direction of the body on the outer circumferential surface of the body, The coupling groove is formed to be inclined with respect to the longitudinal direction of the body portion, and the wing portion is formed with one end coupled to the coupling groove of the long hole and the other end not coupled to the coupling groove of the long hole, and the body portion is clockwise or counterclockwise. It is formed to be wrapped with. The vortex generator also has a problem in that the pressure acting on the exhaust gas may increase because the area occupied by the wing portion or the like is large.

In addition, the vortex tube formed in the prior art has a problem that noise is generated due to a pressure drop of exhaust gas according to the shape of the vortex tube while passing through the vortex tube.

Is a plan view of the vortex tube of, Figure 4 is a cross-sectional view of the exhaust emission reduction device for a vehicle internal combustion engine according to the present invention, Figure 5 is a perspective view showing a twist angle of the vane of the exhaust emission reduction device for a vehicle internal combustion engine according to the present invention, 6 is a flow chart showing the working relationship of the exhaust gas discharge flow through the housing pipe and the vortex pipe of the exhaust gas reduction device for a vehicle internal combustion engine according to the present invention, and FIG. 7 is a vehicle equipped with the exhaust gas reduction device for a vehicle internal combustion engine according to the present invention. It is a state diagram showing that.

As shown in FIG. 1, the exhaust gas reduction device 1 for a vehicle internal combustion engine according to the present invention is connected to the muffler end tail pipe 2-1 of the vehicle 2 and the exhaust gas is introduced and discharged. It comprises a housing tube 10 and a vortex tube 20 mounted inside the housing tube 10 and allowing exhaust gas passing through the housing tube 10 to be discharged while generating a vortex.

The housing tube 10 is a means for efficiently proceeding the exhaust gas discharge flow at the end of the tail pipe 2-1 of the vehicle 2, as shown in FIG. 1, 4 of the internal combustion engine of the vehicle As a discharge pipe through which the moving flow of exhaust gas discharged to the outside through the tail pipe 2-1 is completed by the exhaust stroke during the stroke, an inlet 13 connected to the tail pipe 2-1 is formed at the front end. It has a front body 11 having a constant diameter up to a certain distance, and a rear body 15 whose diameter gradually decreases as it goes from the rear end of the front body 11 to the end forming the outlet 14. A bolt hole 12 is further formed at the inlet 13 side so as to be mounted on the tail pipe 2-1. In the case of mounting the housing tube 10, when the housing tube 10 is inserted into the tail pipe, it is formed to have a constant diameter smaller than the diameter of the tail pipe, and the housing tube 10 is inserted outside the tail pipe. In the case, it is preferable that the diameter at the fastening portion is formed equal to or larger than the outer diameter of the tail pipe so that it can be inserted outside.

Specifically, the housing tube 10 is composed of a front body 11 and a rear body 15, and an inlet 13 is formed at the front end of the front body 11 to allow exhaust gas to flow therein, and the rear body 15 At the rear end of the exhaust port 14 is formed, so that the exhaust gas forms a spiral vortex. And, it consists of a plurality of fastening holes 12 formed in the fastening portion of the inlet side of the front body 11. In addition, noise may be generated around the vortex pipe 20 due to a pressure drop generated while passing through the vortex pipe 20, and an outside air inlet hole 16 may be further formed to prevent or reduce such noise.

The vortex pipe 20 is for controlling the flow rate of the exhaust gas so that the exhaust gas discharged through the housing pipe 10 is discharged while rotating in a spiral shape. As shown in FIG. 2, the discharge flow of the exhaust gas is While forming a spiral vortex, the diameter gradually decreases toward the rear end compared to the diameter of the front end so that the speed increases. A vane 21 is formed to form a spiral vortex, and since the exhaust gas hits the vane and is discharged, the exhaust gas must be discharged while rotating in a spiral. In addition, since the diameter gradually decreases, according to Bernoulli's theorem, the exhaust gas is discharged as a eddy current while increasing the discharge rate, thereby increasing the discharge of exhaust gas, and fuel efficiency by smooth discharge of the exhaust gas. Can bring about an increase. That is, since it is possible to prevent the exhaust gas from flowing back into the engine, it is possible to increase fuel economy and reduce the generation of soot due to the delay in exhaust gas emission.

To this end, as shown in FIGS. 2 and 3, the vortex tube 20 includes a vane 21 formed by twisting at a certain angle after forming a plurality of cutouts 22. As shown in the drawing, the vane 21 is formed by twisting at a certain angle so that the exhaust gas can be discharged while forming a vortex. As shown in Fig. 5, the vane 21 has a twist angle (θ) formed by a tangential line of the circle at the rear end of the vortex tube 20 based on the circle at the tip end of the vortex tube 20. It is formed by twisting to have. In addition, as shown in Fig. 4, the positions of the housing tube 10 and the vortex tube 20 are formed under the following conditions. When the housing tube 10 is formed too long, the exhaust gas discharge rate may be reduced due to the pressure drop generated by the housing tube 10, and thus, it is formed to have a certain length. Accordingly, the length (L) of the housing tube 10 is set to be 80 ~ 200 mm. Next, the vortex tube 20 mounted inside the housing tube 10 is formed so that the outer diameter is the same as the inner diameter of the housing tube 10, and the installation position of the vortex tube 20 is a certain distance ( ℓ ₁ ) It is installed at the rear, and a certain distance (ℓ ₁ ) is preferably 1/4 of the total length (L) of the housing tube. The length (ℓ ₂ ) of the vortex tube 20 is preferably 1/4 of the total length (L) of the housing tube 10, and is formed to be 20 mm to 50 mm in length. The purpose is to allow the exhaust gas to be rapidly discharged while passing through the vortex pipe 20 while increasing the speed and changing into a vortex discharged while rotating. In addition, the length of the vane 21 is formed to be 60 to 80% of the total length (ℓ ₂ ) of the vortex tube 20. The distance (ℓ ₃ ) between the outlet 14 of the housing tube 10 at the rear end of the vortex tube 20 is installed in a range of 40 mm to 100 mm, which is 1/2 of the total length L of the housing tube 10. This is to allow the exhaust gas passing through the vanes 21 to be discharged without being affected by the flow of outside air without contacting the housing pipe 10. In addition, the number of vanes 21 is 6 to 10, so that the area in which the exhaust gas hits the vanes is not too narrow. Accordingly, it is possible to make it easy for the exhaust gas to obtain a rotational force for forming a vortex. That is, the diameter of the inlet 13 of the housing tube 10 and the diameter of the vortex tube 20 so that the exhaust gas passing through the exhaust gas reducing device 1 according to the present invention can quickly exit while forming a vortex in a spiral shape. The diameter of the vane 21 and the diameter of the outlet 14 are formed to gradually decrease. Preferably, the diameter is gradually reduced in a ratio of 5:4:3 so that the exhaust gas passing through the vortex tube 20 can be discharged to the outlet 14 without hitting the housing tube as much as possible. In addition, the rear body 15 of the housing tube is curved and gradually reduced so that the exhaust gas that deviates from the mainstream exhaust gas flow can be easily discharged together along the inner wall of the rear body 15. . The rear body 15 of the housing tube is formed to be approximately 1/4 of the total length L of the housing tube. 6 is an expression of the pressure drop of the exhaust gas, and since the diameter gradually decreases, the pressure decreases in the form of P> P ₁ > P ₂ , and accordingly, the speed is in the order of V ₂ > V ₁ > V. By forming a spiral vortex, the exhaust gas discharge speed is increased, thereby enabling the exhaust gas to be discharged smoothly through the muffler of the vehicle. In addition, as shown in FIGS. 1 and 4, the front body 11 around the vortex tube 20 has an outside air inlet hole 16 for preventing noise due to a pressure drop generated while passing through the vortex tube 20. ) May be added, and since the back pressure drops while passing through the vortex pipe 20, the outside air is introduced through the outside air inlet hole 16, and noise can be reduced or prevented due to the introduction of the outside air. It is preferable that the outside air inlet hole 16 has a diameter of 4 to 5 mm, and the position where the outside air inlet hole 16 is formed is 2/3 of the vortex tube 20 at the rear point of the front end of the vortex tube 20. It is preferably installed between the end points. In addition, the number of the outside air inlet hole 16 is preferably formed in the front body 11 at the same position about 8 to 10. The outside air may be introduced into the housing tube 10 through the outside air inlet hole 16. That is, the pressure of the space between the housing pipe 10 and the vortex pipe 20 is lowered by the exhaust gas discharged at a high speed, and some exhaust gas hitting the vane may be introduced, and the introduced exhaust gas is Noise caused by the eddy current may be generated, and the eddy current may be canceled by the outside air flowing into the outside air inlet hole 16. Thereby noise can be prevented. In addition, noise caused by exhaust gas striking the vanes of the vortex pipe 20 may also have an effect of offsetting the incoming external air.

The operation of the exhaust gas reduction device 1 for a vehicle internal combustion engine according to the present invention having the above configuration will be described in detail.

First, as shown in FIG. 7, the exhaust gas exhaust flow of the exhaust gas is additionally mounted to the end of the tail pipe 2-1 of the vehicle 2 by installing the exhaust gas reduction device 1 for the vehicle internal combustion engine according to the present invention. Through the formation, the exhaust efficiency is maximized and fuel efficiency is improved accordingly.

Here, in a state in which the end of the tail pipe 2-1 is partially inserted into or outside the upper fastening portion of the housing tube 10, the housing tube 10 is tailed using a fastening means such as a bolt. It can be firmly mounted on the pipe 2-1.

On the other hand, by stepping on the accelerator pedal in a state where the engine is started and the internal combustion engine of the vehicle equipped with the smoke reduction device 1 of the present invention starts to drive, the vehicle can be driven, that is, 4 of the internal combustion engine. The stroke (suction, compression, explosion, exhaust) is in progress, and the exhaust gas is discharged through the tail pipe 2-1 according to the exhaust stroke among these four strokes, and the exhaust gas thus discharged is shown in FIG. As described above, a eddy current is induced in the process of being finally discharged to the outside through the pipes of the housing pipe 10 and the vortex pipe 20 through the tail pipe 2-1. In addition, since the diameters of the housing tube 10 and the vortex tube 20 through which the exhaust gas passes are formed to gradually decrease, the discharge rate of the exhaust gas increases while passing through the vortex tube 20. As it passes through the discharge port 14, the speed is further increased and discharged in a spiral vortex, thereby increasing the discharge efficiency of the discharged exhaust gas. That is, since the exhaust gas can be discharged more easily and more at the same time, the possibility of reverse flow of the exhaust gas or the like can be prevented in advance with an increase in the amount of exhaust gas, so that fuel economy improvement can be achieved.

In summary, according to the exhaust gas reduction device 1 for a vehicle internal combustion engine of the present invention, as shown in FIG. 7, the muffler end tailpipe 2-of the vehicle 2 is performed by the exhaust stroke among the four strokes of the internal combustion engine. Through 1), the exhaust gas finally discharged to the outside generates a vortex and is discharged, so that the exhaust efficiency is achieved quickly and the administrative capability of the internal combustion engine is improved, thereby preventing the reverse flow of the exhaust gas of the vehicle or delay in the emission. In addition to output improvement, fuel economy improvement can be achieved.

In addition, by inducing smooth exhaust of exhaust gas by using a vortex-type flow that naturally occurs while driving a vehicle without a separate driving device, it improves the exhaust performance and energy efficiency of the engine, and various parts installed in the intake and exhaust systems. It helps to improve the durability of parts and reduces exhaust noise. In addition, various problems caused by exhaust gas cannot be discharged to the exhaust pipe in time and delayed discharge may be solved.
