Abstract

The present invention relates to an exhaust gas recombustion apparatus of an automobile, in which an asbestos heat insulating material (12) is mounted inside the outer cylinder (11) in order to insulate the high temperature exhaust gas discharged from the internal combustion engine, thereby causing a high temperature inside the outer cylinder (11). Permanent magnet (3) with heat sink (14) attached with heat sink (14) to the ionization when discharge gas is introduced into inlet (1) of outer cylinder (11) has a Curie temperature of 120 ℃ or more and the inlet side is 4,000-4,500 gauss The discharge side ionizes the exhaust gas in a double arrayed ionizer to be 4,500 to 5,500 gauss, and by vortexing the exhaust gas by installing two vortex tubes 20 composed of one set of 5 to 6 in an S-shape. Combustion conditions are further improved.

Description

Re-combustion apparatus of exhaust gas emissions in automobile}

The present invention relates to an exhaust gas recombustion apparatus 23 of a vehicle, and in more detail, the exhaust gas of the automobile is ionized to improve combustion conditions, and the exhaust gas with improved combustion conditions is accelerated by the vortex apparatus 4. After exhausting the exhaust gas smoothly, the exhaust gas is re-burned in the reburn apparatus 23 composed of the diaphragms 6, 7, 8, and the electric heater 10, thereby reducing soot and harmful components in the exhaust gas. In addition, the present invention relates to an exhaust gas reburn apparatus of a vehicle which increases the output speed of the exhaust gas to increase the engine output and changes the structure of the exhaust silencer to reduce the exhaust noise. The engine is classified into a large engine. A diesel engine sucks and compresses only the air inside the cylinder and compresses the fuel by atomizing the fuel when the compressed air temperature rises from 500 ° C to 700 ° C. It is powered by self-ignition by the gasoline engine, and the gasoline engine sucks air mixed with fuel and air in a certain ratio inside the cylinder, compresses it, and ignites the compressed air with a spark plug to cause an explosion. Getting In the case of gasoline engines, the exhaust gases (CO, HC, NOx) emitted from the engine after the explosion are oxidized and reduced by the catalyst of the catalytic converter mounted on a part of the exhaust pipe and then discharged through the silencer at the end of the exhaust pipe. It is supposed to be. However, in the case of diesel engines, since there is no such device at all, the exhaust gas including exhaust gas, which cannot be completely burned, is discharged through the exhaust pipe, which greatly affects the air pollution. In particular, due to the combustion characteristics of diesel engines, a large amount of soot is generated at high loads as well as at low loads, and various studies have been conducted to solve this problem, which is the first priority to be solved at present. The engine reaches the normal temperature after about 30 minutes after the engine is started. Before this, the engine contains a large amount of soot in the exhaust gas due to incomplete combustion, and also a catalyst for oxidizing and reducing the exhaust gas of the gasoline engine. The catalyst does not function properly until it reaches a certain temperature (about 300 ℃). Until these conditions are satisfied, a large amount of harmful gases including soot are discharged, and smoke is also caused by engine aging and poor maintenance. Exhaust gas, including a large amount is emitted. In order to improve the state of the exhaust gas caused by incomplete combustion of the engine, an oxygen sensor or the like is installed in the exhaust pipe to automatically adjust the mixing ratio of fuel and air so that the ideal combustion occurs, but incomplete combustion still occurs, and thus discharge Hazardous gases, etc., are present in a large amount of gas, and aging engines are insignificant in controlling the fuel mixing ratio, and thus, emissions of harmful gases are more severe. A catalytic converter is used to oxidize and reduce harmful components in exhaust gas of a gasoline engine. Not only does it increase the output by allowing the exhaust gas to be discharged smoothly, but there is a limit to the removal of harmful components in the exhaust gas including soot because there is no reburning device. Meanwhile, the conventional muffler installed at the end of the exhaust pipe is installed so that the exhaust pipe connected to the inlet 1 is inserted into the outer cylinder 11 to 70% as shown in FIG. Noise is reduced by discharging and dispersing exhaust gas from the inlet, and the inlet 1 is made relatively higher than the outlet 2, and the inside of the outer cylinder 11 is made double. However, by varying the installation height of the inlet (1) and the outlet (2) in this way, the speed of the exhaust gas is delayed, the exhaust pipe is inserted into the outer cylinder 11, and the outer cylinder 11 is simply doubled to simply reduce the noise. By using it as only slightly filter the dust in the exhaust gas, there was a problem that can not substantially remove the harmful components in the exhaust gas.

The present invention provides an ionizer 22, a vortex device 4 and a reburn apparatus 23 in front of and inside the exhaust gas cylinder of the silencer installed at the end of the exhaust pipe 15 of the automobile to solve the above problems. Therefore, the exhaust gas of the vehicle passes through such a device to reduce soot and harmful constituents in the exhaust gas, to increase the output of the engine by increasing the discharge speed of the exhaust gas, and to reduce the noise by changing the internal structure of the existing silencer. It was for the purpose.

In Fig. 2, the permanent magnets 3 connected to the exhaust pipe silencer in front of the N poles 18 and the S poles 19 are arranged in double and flowed through the magnetic field to ionize the exhaust gas, thereby improving the recombustion condition of the exhaust gas. Let's do it. At this time, it is preferable to attach the heat insulating material (12) made of asbestos or the like to maintain the temperature of the exhaust gas inside the outer cylinder (11) through which the high-temperature exhaust gas discharged from the internal combustion engine passes. In addition, the permanent magnets (3) entering the device to promote the ionization by generating a magnetic field in the exhaust gas can be adjusted according to the size of the exhaust pipe 15 and installed in duplicate, but the magnetic flux density of the inlet side is about 4000-4500 gauss It is necessary to provide a device for lowering the magnetic flux density 4500 to 5500 gauss and to prevent a rise in temperature, which is possible by providing a heat sink 14 or the like outside the permanent magnet 3. In addition, the permanent magnet 3 keeps its magnetic field constant even at high temperatures so that the Curie Temp. Is 120 ° C. or higher so that ionization of the exhaust gas does not change with temperature, and the N pole 18 and the S pole 19. In order to eliminate the repulsion, it is preferable to install them opposite to each other.

The exhaust gas ionized by the permanent magnet 3 is accelerated by the vortex device 4 and guided to the guide passage 5. The vortex pipe 20 provided in the outer cylinder body 11 inlet 1 exhaust pipe 15 is provided in double, and each of the vortex pipes 20 is 5-6 pieces of the S-shaped vortex board 21 each. It is installed by remodeling, and it is effective to adjust the number of the vortex plates 21 suitably according to the magnitude | size of the exhaust pipe 15. As shown in FIGS. 4 and 5, the vortex plate 21 has a height at both ends that is higher than the height of the middle portion, and the middle portion has a parabolic shape so that the vortex tube 20 is inclined than the discharge gas flow direction. It is most effective to arrange radially at equal intervals in the X and at the same time as the S-shaped along the vortex 20. Since the discharged gas is accelerated by the vortex plate 21 of the vortex device 4, the discharge of the gas is discharged without delay, so that the back pressure caused by the delayed discharge of the gas is reduced, so that the engine output is increased. The exhaust gas having passed through is introduced into the compartment 13 partitioned by each of the partitions 6, 7, and 8 via the guide passage 5, and the combustion gas is reburned by the heat transfer heater 10 ( 23). Discharge holes 17 are formed in each of the diaphragms 6, 7 and 8 so as to efficiently increase the temperature inside the outer cylinder 11 and not to delay the discharge of the exhaust gas. The diameter, number and position of the discharge holes 17 can be varied according to the displacement of the engine. The temperature is increased by the heat transfer heater 10 installed in the insulating insulation plate 7 so that the exhaust gas is reburned and decomposed when passing through the discharge hole 17. The temperature sensor switch 9 connected to the heat transfer heater 10 is 50 Power is automatically applied at ℃ to raise the temperature of the compartment 13 to 800 ℃, to enable the temperature sensor switch 9 to automatically operate in accordance with the temperature of the outer cylinder 11 to consume unnecessary storage battery To prevent. Then, the heat transfer heater 10 connected to the temperature sensor switch 9 is installed near the stainless steel plate 8 on the outlet 2 side of FIG. 2 so that the exhaust gas discharged from the exhaust pipe 15 is discharged from the primary plate 6. It is preferable to prevent the heat transfer of the heat transfer heater 10 due to the water vapor particles contained in the discharge gas by passing through the discharge hole 17 of the) directly to the heat transfer heater 10. As shown in Fig. 1, up to about 70% of the exhaust pipe is inserted into the silencer of the exhaust pipe, and the exhaust pipe inserted into the silencer has a myriad of small holes (6) to obtain a noise effect by resistance and resonance when the exhaust gas passes through the hole. However, in the device of the present invention, the exhaust gas accelerated while passing through the vortex device 4 makes a guide passage 15 that is rapidly enlarged inside the outer cylinder 11 to be discharged directly to the first place, thereby making a noise effect. Got Then, the exhaust gas then passes through the respective discharge holes 17 installed in the primary partition 6, the secondary insulation insulating partition 7 and the stainless steel secondary partition 8 as the secondary partition. Since the emission noise is reduced rapidly, the function of the noise reduction device 24 is secured so that the noise effect is superior to that of the original silencer. Each diaphragm 6, 7, 8 is preferably made of a material resistant to corrosion. This can be done by chromium-plating aluminum or using stainless steel, and smoothing the surface to maximize the reflectance is effective for the reburn function. The secondary insulating plate insulation insulating plate (7) is excellent heat transfer because the heat transfer heater (10) is installed, and the heat insulation for the recombustion of the exhaust gas including soot in the compartment (13), such as ceramic, etc. Material is effective.

As described above, the present invention accelerates the harmful components in the exhaust gas which the mixer is incompletely burned in the engine or the catalytic converter does not remove due to the eddy current device 4 and then reburns the heat by the electric heater 10. By increasing the output of the engine, it is possible to drastically reduce the harmful gases including soot emitted to the atmosphere, and to significantly reduce the noise. The results are as follows. For diesel, gasoline, and LPG vehicles, both the new and old vehicles were equipped with the present invention and tested in the same operating conditions. There was a speed increase over / h, the output of about 10% improved, the noise and soot reduced by about 50%. Effect analysis table of design ※ Comparison of increase and decrease when the present product is installed under the same operating conditions as a conventional vehicle, and as shown in the effect analysis table of the present invention in Table 1, the fuel saving is about 7 to 10% when the diesel vehicle is equipped with the present product than the conventional vehicle. LPG cars are reduced by 10%, gasoline cars are reduced by 10-15%, and the feeling of stepping on the accelerator pedal is lightened, and there is no fuel reduction effect when the vehicle is stopped. The gasoline vehicle that had no smell of exhaust gas after 15 minutes of engine start disappeared after about 5 minutes, and the vehicle that smelled LPG from the exhaust gas because of the engine and carburetor had smelled after about 5 minutes. After about 10 minutes, the diesel car disappeared without the spicy smell of diesel, and when the diesel engine was running at low speed and high speed, the color of exhaust gas was changed to colorless or light blue. Gas test report card As shown in the exhaust gas and exhaust gas test results shown in Table 2, 20 to 23% of the exhaust gas, which is 44 to 53% of the exhaust of a conventional diesel vehicle traveling more than 600,000 km, is about 20 minutes after installation. The conventional gasoline vehicle, which was reduced to about 50%, exhibited 0.64% of CO gas and 87 ppm of HC, 0.09% of CO gas and 15 ppm of HC, respectively. Reduction rates of% and 83% are shown. As a result, the engine power is increased to save fuel and at the same time reduce smoke, thereby significantly reducing the air pollution.
