Description

Technical Field

[0001] The invention belongs to the technical field of internal combustion engines, and in particular to an energy-saving internal combustion engine emission reduction system. Background Art

[0002] The exhaust gas of internal combustion engines is one of the main sources of air pollutants. When gasoline is burned in a car engine and releases heat, its products include a large number of harmful substances such as carbon monoxide, nitrogen oxides, hydrocarbons and solid suspended matter. In the early stage of the automobile market, gasoline containing tetraethyl lead was very popular because it could withstand higher compression environments and lubricate engines and valves. However, with the advancement of technology, people found that leaded gasoline not only seriously exceeded the exhaust gas standard but also damaged the three-way catalytic converter, so leaded gasoline gradually withdrew from the market. my country banned the sale of leaded gasoline in 2006, but some gasoline additives on the market still contain a small amount of lead. These lead will accumulate in the catalyst carrier of the three-way catalytic converter after combustion. At the same time, during the operation of the internal combustion engine, a large number of carbon deposits will accumulate in the catalyst carrier of the three-way catalytic converter, causing the catalyst to be "poisoned" and unable to work, so that the exhaust emissions of the internal combustion engine cannot react and convert in the catalyst carrier plate, resulting in increased exhaust emissions. Summary of the invention

[0003] In order to make up for the deficiencies of the prior art and solve the problem that carbon deposits and impurities generated during the operation of the internal combustion engine clog the catalyst carrier plate on the three-way catalytic converter, making it impossible for the exhaust gas to react and convert in the catalyst carrier plate, the present invention proposes an energy-saving internal combustion engine emission reduction system.

[0004] The technical solution adopted by the present invention to solve its technical problem is: the energy-saving internal combustion engine emission reduction system described in the present invention includes a main body, the main body is hollow inside, the upper and lower ends of the main body are respectively fixedly connected to the intake pipe and the exhaust pipe, the inner wall of the main body is provided with a slide groove, the slide groove is symmetrically distributed along the center line of the main body, a slider is slidably installed in the slide groove, a cleaning plate is fixedly installed at one end of the slider away from the inner wall of the main body, a spring is fixedly connected to the surface of one side of the slider close to the exhaust pipe, the other end of the spring is fixedly connected to the surface of the slide groove close to one end of the exhaust pipe, the cleaning plate is hollow inside, and the cleaning plate is close to the exhaust pipe. An exhaust hole is provided on the surface close to the intake pipe, and a through hole 1 is provided on the surface of the cleaning plate close to the exhaust pipe. The exhaust hole and the through hole 1 correspond one to one and are interconnected. A push rod 1 is fixedly installed on the surface of the cleaning plate close to the exhaust pipe. The inside of the push rod 1 is hollow, and the push rod 1 corresponds one to one to the through hole 1, and the push rod 1 and the through hole 1 are interconnected. A catalyst carrier plate is fixedly installed at one end of the main body close to the exhaust pipe, and a through hole 2 is provided on the catalyst carrier plate, which corresponds one to one to the push rod 1. The end of the push rod 1 away from the cleaning plate is inserted into the through hole 2.

[0005] During operation, when the internal combustion engine starts to work, the internal combustion engine will generate high-temperature exhaust gas. At this time, the high-temperature exhaust gas flows into the main body through the intake pipe. Since the slider one is slidably installed in the slide groove, and a cleaning plate is fixedly installed at one end of the slider one, when the high-temperature exhaust gas flows into the main body, the high-temperature exhaust gas flows downward along the main body to squeeze the cleaning plate, causing the cleaning plate to move downward, driving the push rod one on the cleaning plate to move downward and contact the through hole two on the catalyst carrier plate close to the exhaust pipe. Then, under the pressure of the high-temperature exhaust gas, the push rod one extends into the through hole two, scrapes off the carbon deposits and impurities accumulated in the through hole two, and separates them, and then discharges them with the exhaust gas. At this time, since the cleaning plate is provided with exhaust holes, the high-temperature exhaust gas will enter the cleaning plate along the exhaust holes while squeezing the cleaning plate. Then, the high-temperature exhaust gas flows into the inside of the push rod one along the through hole one. While the push rod one pushes out the carbon deposits and impurities, the high-temperature exhaust gas also flows out from the top of the push rod one and enters the through hole two. The catalyst coating on the upper part of the cleaning plate is directly in contact with the cleaning plate to react, thereby catalyzing and decomposing the pollutants in the exhaust gas and reducing the emission of the exhaust gas. At the same time, it avoids carbon deposits and impurities clogging the through hole two on the catalyst carrier plate, resulting in the high-temperature exhaust gas being unable to enter the through hole two on the catalyst carrier plate to fully complete the conversion, thereby causing the increase in exhaust gas emissions. At the same time, since the cleaning plate and the slider one are fixedly installed, when the cleaning plate moves downward, it drives the slider to move downward together, so that the spring one under the slider is compressed. When the high-temperature exhaust gas flows out with the push rod, the squeezing force of the high-temperature exhaust gas on the cleaning plate will decrease, and the spring begins to recover its deformation upward, pushing the cleaning plate to move upward, so that the cleaning plate can reciprocate up and down in the main body to repeat the cleaning work. At the same time, after the cleaning plate is moved up, the high-temperature exhaust gas can be more evenly in contact with the catalyst coating inside the through hole two, thereby further improving the conversion of the exhaust gas and reducing the exhaust gas emission.

[0006] The cleaning agent tube is provided with a through hole, and a cleaning agent tube is slidably installed in the cleaning agent tube, and a piston is slidably installed on the part of the cleaning agent tube extending into the water inlet hole, and the other part of the cleaning agent tube extends out of the air push chamber from a direction perpendicular to the center line of the main body, and then passes through the outside of the main body and is connected to the cleaning agent storage tank. The part of the cleaning agent tube extending into the water inlet pipe is slidably installed with a piston, and the piston is provided with a liquid inlet channel. When the piston is located at the turning point of the cleaning agent tube, the outlet of the liquid inlet channel is respectively connected with the part of the cleaning agent tube extending into the water inlet hole and the part perpendicular to the center line of the main body, and the upper end of the piston is fixedly installed with a connecting rod, and the upper end of the connecting rod passes through the cleaning agent tube and extends into the air inlet pipe. A push plate is fixedly installed on the upper end of the connecting rod, and the push plate and the air inlet pipe slide relatively. A through hole three is provided on the push plate, and a mounting bracket is fixedly installed on the upper end of the push plate. A rotating shaft is rotatably mounted on the mounting frame, a torsion spring is fixedly mounted on the rotating shaft, one end of the torsion spring is fixedly connected to the mounting frame, and the other end is fixedly connected to the rotating shaft, a baffle is fixedly mounted on the rotating shaft, the baffle is located just above the through hole three and closes the through hole three, a ratchet is fixedly mounted on the rotating shaft, the ratchet is located at one end of the rotating shaft extending out of the mounting frame close to the inner wall of the intake pipe, a block groove is fixedly mounted on the mounting frame, the opening position of the block groove is just opposite to the ratchet, and the block groove near the ratchet is A spring 2 is fixedly connected to the surface of one side, and a block is fixedly connected to the other end of the spring 2, and the block cooperates with the ratchet. A push rod 2 is fixedly installed on the inner wall of the intake pipe, and the push rod 2 is located above the push plate. A spring 3 is fixedly connected to the lower surface of the push plate, and the other end of the spring 3 is fixedly connected to a spring bracket, and the spring bracket is fixedly installed on the inner wall of the intake pipe. A push rod 3 is fixedly installed on the inner wall of the intake pipe, and the push rod 3 is located below the push plate, and the upper end of the push rod 3 is directly opposite to the baffle.

[0007] During operation, when the internal combustion engine starts to work, high-temperature cleaning agent is introduced into the cleaning agent pipe. At this time, the high-temperature exhaust gas enters the intake pipe and squeezes the push plate, pushing the push plate to move downward, driving the connecting rod to move downward, so that the piston moves downward in the cleaning agent pipe to the turning point of the cleaning agent pipe. The push plate moves downward and drives the baffle plate to move downward together, so that the push rod three passes through the through hole three on the push plate. After that, the baffle plate contacts the push rod three. At this time, the baffle plate is pushed open by the action of the push rod three and deflected upward. At this time, the push plate will compress the spring three. The baffle is fixedly mounted on the rotating shaft, so when the baffle rotates upward, it drives the rotating shaft to rotate together, and then drives the ratchet wheel to rotate together, so that the ratchet wheel and the clamping block are in contact and locked, and can only be transmitted in one direction, and cannot return to the original position in the reverse direction, so that the liquid inlet pipeline on the piston is always at the turning point of the cleaning agent pipe, so that the high-temperature cleaning agent can flow into the water inlet hole through the liquid inlet channel on the piston, and then flow into the push rod 1 through the water inlet hole, and then flow into the through hole 2 through the water outlet in the push rod 1, so as to remove the carbon deposits and impurities in the through hole 2. The cleaning effect of the cleaning agent tube is improved by further cleaning and cleaning, and the exhaust gas can be further ensured to contact the catalytic coating in the through hole 2, so that the exhaust gas emission is reduced. At the same time, the high-temperature cleaning agent flows into the water inlet hole only when the liquid inlet channel on the piston moves to the turning point of the cleaning agent tube, thereby reducing the waste of the high-temperature cleaning agent. When the high-temperature exhaust gas flows into the interior of the main body through the through hole 3 on the push plate, the high-temperature exhaust gas extrusion on the push plate will be reduced, and the compression of the spring 3 will decrease and begin to recover upward, pushing the push plate to move upward, thereby driving the piston to move upward to the cleaning agent tube above the turning point of the cleaning agent tube, so that the piston liquid inlet channel is separated from the turning point of the cleaning agent tube, and the entrance of the cleaning agent tube into the water inlet hole is blocked by the piston, avoiding the cleaning agent from flowing into the water inlet hole all the time, causing the waste of cleaning agent and increasing the use cost. At this time, the push plate moves upward and contacts with the push rod 2, and the push rod 2 pushes the block back from the ratchet into the block groove, so that the baffle returns to its initial position under the action of the torsion spring, and then repeats the above movement. Preferably, an irregular metal wire is fixedly mounted on the outer wall of the first push rod, and the irregular metal wire is in contact with the second through hole.

[0008] During operation, when the cleaning plate moves downward under the action of the high-temperature exhaust gas, the push rod 1 moves downward with the cleaning plate. Since an irregular metal wire is fixedly installed outside the push rod, and the metal wire is in contact with the inner wall of the through hole 2, when the push rod 1 moves into the through hole 2, the irregular metal wire will move into the through hole 2 with the push rod 1, thereby scraping off the carbon deposits and impurities remaining inside the through hole 2, further making the contact between the high-temperature exhaust gas and the catalyst coating more complete and thorough, making the exhaust gas conversion more complete, thereby reducing exhaust gas emissions, and avoiding the incomplete exhaust gas conversion caused by the residual carbon deposits and impurities on the inner wall of the through hole 2, which increases exhaust gas emissions.

[0009] Preferably, a scraper is fixedly mounted on the push rod, the scraper is in contact with the inner wall of the main body, there are a plurality of scrapers evenly distributed in the main body; the scraper will not interfere with the movement of the push rod.

[0010] During operation, when the exhaust gas squeezes the cleaning plate downward, the cleaning plate moves downward, thereby driving the push rod to move downward, so that the scraper fixed on the push rod moves downward with the push rod to remove the carbon deposits and impurities on the inner wall of the main body, and the impurities that fall off are discharged to the outside of the main body along with the exhaust gas discharged outward, avoiding excessive accumulation of carbon deposits and impurities on the inner wall of the main body to hinder the work of the cleaning plate, and clogging the exhaust holes on the cleaning plate, resulting in incomplete exhaust conversion and increased exhaust emissions.

[0011] Preferably, the cleaning agent tube is fixedly connected to a water pipe at the opening of the part perpendicular to the main body, the water pipe is spirally wrapped around the outer wall of the main body, one end of the water pipe close to the exhaust pipe is fixedly connected to an inlet pipe, an insulating shell is fixedly installed on the outside of the water pipe, the inlet pipe extends out of the insulating shell, and one end of the inlet pipe extending out of the insulating shell is fixedly connected to the cleaning agent storage box.

[0012] During operation, since the cleaning agent tube is fixedly connected with a water pipe at right angles to the opening of the main body, and the water pipe is spirally wrapped around the outer wall of the main body, when the high-temperature cleaning agent flows into the water pipe through the inlet pipe, the high-temperature cleaning agent will flow in the water pipe and flow through the inlet of the cleaning agent tube, so that the high-temperature cleaning agent can preheat and keep the inside of the main body warm. At the same time, when the internal combustion engine is working normally, the cleaning agent can be heated by the temperature of the exhaust gas to ensure that the temperature of the cleaning agent entering the main body is high, thereby ensuring that the temperature inside the main body is at a relatively high temperature, thereby further improving the reaction efficiency between the high-temperature exhaust gas and the catalyst coating, and improving the conversion rate of the exhaust gas, thereby avoiding the incomplete reaction of the exhaust gas with the catalyst coating due to insufficient temperature, resulting in a low exhaust gas conversion rate and a large exhaust gas emission.

[0013] Preferably, a retaining ring is fixedly installed inside the cleaning plate, and a plurality of air holes are opened on the retaining ring.

[0014] During operation, when high-temperature exhaust gas flows into the cleaning plate through the exhaust hole, since a retaining ring is fixedly installed inside the cleaning plate, the cleaning agent flowing in through the water inlet hole will flow into the retaining ring, and the exhaust gas flows into the space outside the retaining ring inside the cleaning plate through the exhaust hole. In the main body installed in a vertical state, the exhaust gas entering the cleaning plate makes the cleaning agent in the retaining ring airtight and promotes the cleaning agent to flow downward into the top rod, thereby avoiding the cleaning agent from flowing back into the main body through the exhaust hole, resulting in waste of cleaning agent and increased use cost.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The energy-saving internal combustion engine emission reduction system described in the present invention is provided with a cleaning plate, a slide groove, a slider 1, and a push rod 1 so that when the cleaning plate moves downward, it drives the push rod 1 to move toward the inside of the through hole 2 on the catalyst carrier plate, thereby cleaning the carbon deposits and impurities inside the through hole 2 on the catalyst carrier plate, thereby avoiding the through hole 2 on the catalyst carrier plate being clogged by carbon deposits and impurities, resulting in the exhaust gas and the catalyst coating inside the through hole 2 being unable to react, resulting in incomplete exhaust gas conversion and increased exhaust gas emissions.

[0017] 2. The energy-saving internal combustion engine emission reduction system described in the present invention, by arranging a push plate, a connecting rod, a piston, a ratchet, a baffle, a block, a spring three, a push rod two, and a push rod three, when the exhaust gas enters the intake pipe, the push plate is pushed downward to move the liquid inlet channel on the piston to the turning point of the cleaning agent pipe, so that the cleaning agent pipe transports cleaning agent inward; when the exhaust gas flows into the interior of the main body from the three through holes on the push plate, the push plate moves upward under the action of the spring three, pulling the piston to move upward together, so that the liquid inlet channel on the piston is separated from the turning point of the cleaning agent pipe, thereby avoiding the cleaning agent pipe always transporting freshener to the inside of the water inlet pipe, causing waste of cleaning agent and increased cost.

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] like Figures 1 to 6 As shown, the energy-saving internal combustion engine emission reduction system described in the present invention, the technical solution adopted by the present invention to solve its technical problems is: the energy-saving internal combustion engine emission reduction system described in the present invention comprises a main body 1, the main body 1 is hollow inside, the upper and lower ends of the main body 1 are respectively fixedly connected with an intake pipe 11 and an exhaust pipe 12, a slide groove 13 is provided on the inner wall of the main body 1, the slide groove 13 is symmetrically distributed along the center line of the main body 1, a slider 35 is slidably installed in the slide groove 13, a cleaning plate 3 is fixedly installed at one end of the slider 35 away from the inner wall of the main body 1, a spring 36 is fixedly connected to the surface of one side of the slider 35 close to the exhaust pipe 12, the other end of the spring 36 is fixedly connected to the surface of the slide groove 13 close to one end of the exhaust pipe 12, the cleaning plate 3 is hollow inside, The surface of the cleaning plate 3 close to the intake pipe 11 is provided with an exhaust hole 31, and the surface of the cleaning plate 3 close to the exhaust pipe 12 is provided with a through hole 32, the exhaust hole 31 and the through hole 32 correspond one to one and are interconnected, a push rod 34 is fixedly installed on the surface of the cleaning plate 3 close to the exhaust pipe 12, the push rod 34 is hollow inside, the push rod 34 and the through hole 32 correspond one to one, and the push rod 34 and the through hole 32 are connected, a catalyst carrier plate 8 is fixedly installed at one end of the main body 1 close to the exhaust pipe 12, the catalyst carrier plate 8 is provided with a through hole 2 33 corresponding one to one with the push rod 1 34, and the end of the push rod 1 34 away from the cleaning plate 3 is inserted into the through hole 2 33.

[0028] During operation, when the internal combustion engine starts to work, the internal combustion engine will generate high-temperature exhaust gas. At this time, the high-temperature exhaust gas flows into the main body 1 through the intake pipe 11. Since the slider 135 is slidably installed in the slide groove 13, and the cleaning plate 3 is fixedly installed at one end of the slider 13, when the high-temperature exhaust gas flows into the main body 1, the high-temperature exhaust gas flows downward along the main body 1 and squeezes the cleaning plate 3, so that the cleaning plate 3 moves downward, driving the top rod 134 on the cleaning plate 3 to move downward and contact with the through hole 23 on the catalyst carrier plate 8 near the exhaust pipe 12. 3, and then, under the pressure of the high-temperature exhaust gas, the push rod 1 34 extends into the interior of the through hole 2 33, scrapes off and separates the carbon deposits and impurities accumulated in the through hole 2 33, and then discharges them with the exhaust gas. At this time, since the exhaust hole 31 is opened on the cleaning plate 3, the high-temperature exhaust gas will enter the cleaning plate 3 along the exhaust hole 31 while squeezing the cleaning plate 3, and then the high-temperature exhaust gas flows into the interior of the push rod 1 34 along the through hole 1 32. When the push rod 1 34 pushes out the carbon deposits and impurities, the high-temperature exhaust gas also flows out from the top of the push rod 1 34. The exhaust gas flows out and directly contacts the catalyst coating inside the second through hole 33 to react, thereby catalyzing and decomposing the pollutants in the exhaust gas and reducing the exhaust gas emissions. At the same time, it avoids carbon deposits and impurities blocking the second through hole 33 on the catalyst carrier plate 8, resulting in the high-temperature exhaust gas being unable to enter the second through hole 33 on the catalyst carrier plate 8 to fully complete the conversion, thereby causing the increase in exhaust gas emissions. At the same time, since the cleaning plate 3 is fixedly installed with the slider 1 35, when the cleaning plate 3 moves downward, the slider 1 35 is driven to move downward together, so that the spring 1 36 under the slider is compressed. When the high-temperature exhaust gas flows out with the push rod, the squeezing force of the high-temperature exhaust gas on the cleaning plate 3 will decrease, and the spring begins to recover its deformation upward, pushing the cleaning plate 3 to move upward, so that the cleaning plate 3 can reciprocate up and down in the main body 1 to repeat the cleaning work. At the same time, after the cleaning plate 3 moves upward, the high-temperature exhaust gas can be more evenly contacted with the catalyst coating inside the second through hole 33, thereby further improving the conversion of the exhaust gas and reducing the exhaust gas emissions.

[0029] As an embodiment of the present invention, a push rod 21 is fixedly installed on the upper surface of the cleaning plate 3, and an air push chamber 2 is slidably installed outside the push rod 21. The air push chamber 2 is fixedly installed on the inner wall of the main body 1 through a support column. A water inlet hole 4 is opened in the push rod 21, and a cleaning agent pipe 41 is slidably installed in the water inlet hole 4. A part of the cleaning agent pipe 41 extends into the water inlet hole 4, and another part of the cleaning agent pipe 41 extends out of the air push chamber 2 from a direction perpendicular to the center line of the main body 1, and then passes through the outside of the main body 1 and is connected to the cleaning agent storage tank. The part of the cleaning agent pipe 41 extending into the water inlet hole 44 is slidably installed with an active The piston 42 is provided with a liquid inlet channel 421. When the piston 42 is located at the turning point of the cleaning agent tube 41, the outlet of the liquid inlet channel 421 is respectively connected with the part of the cleaning agent tube 41 extending into the water inlet hole 4 and the part perpendicular to the center line of the main body 1. A connecting rod 43 is fixedly installed on the upper end of the piston 42. The upper end of the connecting rod 43 passes through the cleaning agent tube 41 and extends into the air inlet pipe 11. A push plate 53 is fixedly installed on the upper end of the connecting rod 43, and the push plate 53 slides relatively with the air inlet pipe 11. A through hole 3 is provided on the push plate 53. A mounting bracket 51 is fixedly installed on the upper end of the push plate 53. The mounting bracket A rotating shaft 58 is rotatably mounted on the mounting frame 51, and a torsion spring 59 is fixedly mounted on the rotating shaft 58. One end of the torsion spring 59 is fixedly connected to the mounting frame 51, and the other end is fixedly connected to the rotating shaft 58. A baffle 52 is fixedly mounted on the rotating shaft 58, and the baffle 52 is located just above the through hole three and closes the through hole three. A ratchet 7 is fixedly mounted on the rotating shaft 58, and the ratchet 7 is located at one end of the rotating shaft 58 extending out of the mounting frame 51 close to the inner wall of the intake pipe 11. A block groove 54 is fixedly mounted on the mounting frame 51, and the opening position of the block groove 54 is just opposite to the ratchet 7. The side surface of the block groove 54 close to the ratchet 7 A spring 2 542 is fixedly connected to the surface, and a block 541 is fixedly connected to the other end of the spring 2 542. The block 541 cooperates with the ratchet 7. A push rod 2 6 is fixedly installed on the inner wall of the intake pipe 11, and the push rod 2 6 is located above the push plate 53. A spring 3 55 is fixedly connected to the lower surface of the push plate 53, and a spring bracket 56 is fixedly connected to the other end of the spring 3 55. The spring bracket 56 is fixedly installed on the inner wall of the intake pipe 11. A push rod 3 57 is fixedly installed on the inner wall of the intake pipe 11. The push rod 3 57 is located below the push plate 53, and the upper end of the push rod 3 57 is opposite to the baffle 52.

[0030] During operation, when the internal combustion engine starts to work, high-temperature cleaning agent is introduced into the cleaning agent pipe 41. At this time, the high-temperature exhaust gas enters the intake pipe 11 and squeezes the push plate 53, pushing the push plate 53 to move downward, driving the connecting rod 43 to move downward together, so that the piston 42 moves downward in the cleaning agent pipe 41 to the turning point of the cleaning agent pipe 41. The push plate 53 moves downward and drives the baffle plate 52 to move downward together, so that the push rod 3 57 passes through the through hole 3 on the push plate. After that, the baffle plate 52 contacts the push rod 3 57. At this time, the baffle plate 52 is pushed open by the action of the push rod 3 57 and deflected upward. At this time, the push plate 53 will press the spring 3 55 The baffle plate 52 is fixedly mounted on the rotating shaft 58, so when the baffle plate 52 rotates upward, the rotating shaft 58 is driven to rotate together, and then the ratchet wheel 7 is driven to rotate together, so that the ratchet wheel 7 and the clamping block 541 are in contact and locked, and can only be transmitted in one direction, and cannot be reversed back to the original position, so that the liquid inlet pipe 421 on the piston 42 is always at the turning point of the cleaning agent pipe 41, so that the high-temperature cleaning agent can flow into the water inlet hole 4 through the liquid inlet channel 421 on the piston 42, and then flow into the push rod 1 34 through the water inlet hole 4, and flow into the through hole 2 33 through the water outlet in the push rod 1 34, and the through hole 2 33 is pressed. The carbon deposits and impurities in the through hole 33 are further removed and cleaned, thereby improving the removal effect of the carbon deposits and impurities in the through hole 33, further ensuring that the exhaust gas can contact the catalytic coating in the through hole 33, so that the exhaust gas emission is reduced. At the same time, the high-temperature cleaning agent flows into the water inlet hole 4 only when the liquid inlet channel 421 on the piston 42 moves to the turning point of the cleaning agent pipe 41, thereby reducing the waste of the high-temperature cleaning agent. When the high-temperature exhaust gas flows into the inside of the main body 1 through the through hole 3 on the push plate 53, the high-temperature exhaust gas extrusion on the push plate 53 will be reduced, the compression of the spring 3 55 will decrease and start to recover upward, pushing the spring 3 55 to move upward. The push plate 53 moves upward, thereby driving the piston 42 to move upward into the cleaning agent tube 41 above the turning point of the cleaning agent tube 41, so that the liquid inlet channel 421 of the piston 42 is separated from the turning point of the cleaning agent tube 41, and the entrance of the cleaning agent tube 41 into the water inlet hole 4 is blocked by the piston 42, thereby preventing the cleaning agent from flowing into the water inlet hole 4 all the time, causing waste of cleaning agent and increasing the cost of use. At this time, the push plate 53 moves upward and contacts with the push rod 2 6, and the push rod 2 6 pushes the block 541 back from the ratchet 7 into the block groove 54, so that the baffle 53 returns to its initial position under the action of the torsion spring 59, and then repeats the above movement.

[0031] As an implementation mode of the present invention, an irregular metal wire is fixedly mounted on the outer wall of the first push rod 34 , and the irregular metal wire is in contact with the second through hole 33 .

[0032] During operation, when the cleaning plate 3 moves downward under the action of the high-temperature exhaust gas, the push rod 1 34 moves downward together with the cleaning plate 3. Since an irregular metal wire is fixedly installed outside the push rod, and the metal wire contacts the inner wall of the through hole 2 33, when the push rod 1 34 moves into the through hole 2 33, the irregular metal wire will move into the through hole 2 33 together with the push rod 1 34, thereby scraping off the carbon deposits and impurities remaining inside the through hole 2 33, further making the contact between the high-temperature exhaust gas and the catalyst coating more complete and thorough, making the exhaust gas conversion more complete, thereby reducing exhaust gas emissions, and avoiding the residual carbon deposits and impurities on the inner wall of the through hole 2 33 resulting in incomplete exhaust gas conversion, which increases exhaust gas emissions.

[0033] As an embodiment of the present invention, a scraper 22 is fixedly mounted on the push rod 21 , and the scraper 22 contacts the inner wall of the main body 1 . There are a plurality of scrapers 22 , which are evenly distributed in the main body 1 . The scraper 22 will not interfere with the movement of the push rod 21 .

[0034] During operation, when the exhaust gas squeezes the cleaning plate 3 downward, the cleaning plate 3 moves downward, thereby driving the push rod 21 to move downward together, so that the scraper 22 fixed on the push rod 21 moves downward together with the push rod 21, and the carbon deposits and impurities on the inner wall of the main body 1 are removed, and the impurities that fall off are discharged to the outside of the main body 1 together with the exhaust gas discharged outward, thereby avoiding excessive accumulation of carbon deposits and impurities on the inner wall of the main body 1 to hinder the work of the cleaning plate 3, and clogging the exhaust holes 31 on the cleaning plate 3, resulting in incomplete exhaust conversion and increased exhaust emissions.

[0035] As an embodiment of the present invention, the cleaning agent pipe 41 is fixedly connected to a water pipe 44 at a partial opening perpendicular to the main body 1, and the water pipe 44 is spirally wrapped around the outer wall of the main body 1. The water pipe 44 is fixedly connected to an inlet pipe 45 at one end close to the exhaust pipe 12, and an insulating shell 14 is fixedly installed on the outside of the water pipe 44. The inlet pipe 45 extends out of the insulating shell 14, and one end of the inlet pipe 45 extending out of the insulating shell 14 is fixedly connected to the cleaning agent storage box.

[0036] During operation, since the cleaning agent tube 41 is fixedly connected with the water pipe 44 at a part of the opening perpendicular to the main body 1, and the water pipe 44 is spirally wrapped around the outer wall of the main body 1, when the high-temperature cleaning agent flows into the water pipe 44 through the inlet pipe 45, the high-temperature cleaning agent will flow in the water pipe 44 and flow to the entrance of the cleaning agent tube 41, so that the high-temperature cleaning agent preheats and keeps the inside of the main body 1 warm. At the same time, when the internal combustion engine is working normally, the cleaning agent can be heated by the temperature of the exhaust gas to ensure that the temperature of the cleaning agent entering the main body 1 is high, thereby ensuring that the temperature inside the main body 1 is at a relatively high temperature, thereby further improving the reaction efficiency between the high-temperature exhaust gas and the catalyst coating, and improving the conversion rate of the exhaust gas, thereby avoiding the incomplete reaction of the exhaust gas with the catalyst coating due to insufficient temperature, resulting in a low exhaust gas conversion rate and a large exhaust gas emission.

[0037] As an embodiment of the present invention, a retaining ring 37 is fixedly installed inside the cleaning plate 3, and a plurality of air holes are opened on the retaining ring 37.

[0038] During operation, when high-temperature exhaust gas flows into the cleaning plate 3 through the exhaust hole 31, since a retaining ring 37 is fixedly installed inside the cleaning plate 3, the cleaning agent flowing in through the water inlet hole 4 will flow into the retaining ring 37, and the exhaust gas flows into the space outside the retaining ring 37 inside the cleaning plate 3 through the exhaust hole 31. In the main body 1 installed in a vertical state, the exhaust gas entering the cleaning plate 3 makes the cleaning agent in the retaining ring 37 airtight and promotes the cleaning agent to flow downward into the top rod 34, thereby avoiding the cleaning agent from flowing back into the main body 1 through the exhaust hole 31, resulting in waste of cleaning agent and increased use cost.

[0039] The specific workflow is as follows:

[0040] During operation, when the internal combustion engine starts to work, the internal combustion engine will generate high-temperature exhaust gas. At this time, the high-temperature exhaust gas flows into the interior of the main body 1 through the intake pipe 11. Since the slider is slidably installed in the slide groove 13, and a cleaning plate 3 is fixedly installed at one end of the slider 35, when the high-temperature exhaust gas flows into the interior of the main body 1, the high-temperature exhaust gas flows downward along the main body 1 to squeeze the cleaning plate 3, so that the cleaning plate 3 flows downward, driving the push rod 134 on the cleaning plate 3 to move downward and contact the through hole 233 on the catalyst carrier plate 8 near the exhaust pipe 12. Under the pressure of the high-temperature exhaust gas, the push rod 134 extends into the interior of the through hole 233, and pushes the carbon deposits and impurities accumulated in the through hole 233 out of the through hole 233. At this time, since the cleaning plate 3 is provided with an exhaust hole 31, the high-temperature exhaust gas When squeezing the cleaning plate 3, the exhaust hole 31 will enter the cleaning plate 3, and then the high-temperature exhaust gas will flow into the inside of the push rod 34 along the through hole 1. When the push rod 1 34 pushes out the carbon deposits and impurities, the high-temperature exhaust gas will also flow out from the top of the push rod 1 34 and directly contact the catalyst coating inside the through hole 2 33 to react, thereby achieving the conversion of the exhaust gas. The cleaning plate 3 is fixedly installed between the slider 1 35, so when the cleaning plate 3 moves downward, it drives the slider 1 35 to move downward together, so that the spring 1 36 under the slider is compressed. When the high-temperature exhaust gas flows out with the push rod, the squeezing force of the high-temperature exhaust gas on the cleaning plate 3 will decrease, and the spring will begin to recover its deformation upward, pushing the cleaning plate 3 to move upward, and the cleaning agent pipe 41 will be filled with high-temperature The cleaning agent, at this time, the high-temperature exhaust gas enters the intake pipe 11 and squeezes the push plate 53, pushing the push plate 53 to move downward, driving the connecting rod 43 to move downward together, so that the piston 42 moves downward in the cleaning agent pipe 41 to the turning point of the cleaning pipe, and the push plate 53 moves downward to drive the baffle plate 52 to move downward together, so that the baffle plate 52 contacts the push rod three 57. At this time, the baffle plate 52 is pushed open by the push rod three 57 and deflected upward. At this time, the push plate 53 will compress the spring three 55. Since the baffle plate 52 is fixedly installed on the rotating shaft 58, the baffle plate 52 drives the rotating shaft 58 to rotate together when it rotates upward, and then drives the ratchet 7 to rotate together, so that the ratchet 7 contacts with the block 541 and is locked, thereby making the liquid inlet pipe 421 on the piston 42 The cleaning agent pipe 41 is always at the turning point, so that the high-temperature cleaning agent can flow into the water inlet hole 4 through the liquid inlet channel 421 on the piston 42. When the high-temperature exhaust gas flows into the interior of the main body 1 through the through hole 3 on the push plate 53, the high-temperature exhaust gas squeeze on the push plate 53 will be reduced, and the compression of the spring 3 55 will decrease and begin to recover upward, pushing the push plate 53 to move upward, thereby driving the piston 42 to move upward so that the liquid inlet channel 421 of the piston 42 is separated from the turning point of the cleaning agent pipe 41. When the cleaning plate 3 moves downward under the action of the high-temperature exhaust gas, the push rod 1 34 moves downward with the cleaning plate 3. Since an irregular metal wire is fixedly installed on the outside of the push rod, and the metal wire is in contact with the inner wall of the through hole 2 33, when the push rod 1 34 moves into the through hole 2 33,The irregular metal wire will move into the second through hole 33 together with the push rod 1 34. When the exhaust gas presses the cleaning plate 3 downward, the cleaning plate 3 moves downward, thereby driving the push rod 21 to move downward together, so that the scraper 22 fixed on the push rod 21 moves downward together with the push rod 21. When the high-temperature cleaning agent flows into the water pipe 44 through the inlet pipe 45, the high-temperature cleaning agent will flow in the water pipe 44 and flow to the inlet of the cleaning pipe, so that the high-temperature cleaning agent preheats and keeps the inside of the main body 1 warm, thereby ensuring that the inside of the main body 1 is The temperature of the inner part is at a relatively high temperature, and the heat-insulating shell 14 further isolates the heat of the high-temperature cleaning agent flowing in the water pipe 44. When the high-temperature tail gas flows into the inside of the cleaning plate 3 through the tail gas hole 31, since the cleaning plate 3 is fixedly installed with a retaining ring 37, the cleaning agent flowing in through the water inlet hole 4 will flow into the retaining ring 37, and the tail gas flows into the outside of the retaining ring 37 inside the cleaning plate 3 through the tail gas hole 31, squeezing and blocking the cleaning agent in the retaining ring 37, and prompting the cleaning agent to flow downward into the top rod 34.

A push rod 2 (6) is fixedly installed on the inner wall of the air intake pipe (11), and the push rod 2 (6) is located above the push plate (53). A spring 3 (55) is fixedly connected to the lower surface of the push plate (53), and the other end of the spring 3 (55) is fixedly connected to a spring bracket (56), and the spring bracket (56) is fixedly installed on the inner wall of the air intake pipe (11). A push rod 3 (57) is fixedly installed on the inner wall of the air intake pipe (11), and the push rod 3 (57) is located below the push plate, and the upper end of the push rod 3 (57) is directly opposite to the baffle (52); An irregular metal wire is fixedly mounted on the outer wall of the first push rod (34), and the irregular metal wire is in contact with the second through hole (33); A scraper (22) is fixedly mounted on the push rod (21), the scraper (22) is in contact with the inner wall of the main body (1), there are a plurality of scrapers (22), which are evenly distributed in the main body (1); the scraper (22) will not interfere with the movement of the push rod (21); A water pipe (44) is fixedly connected to a portion of the opening of the cleaning agent pipe (41) perpendicular to the main body (1); the water pipe (44) is spirally wound around the outer wall of the main body (1); an inlet pipe (45) is fixedly connected to one end of the water pipe (44) close to the exhaust pipe; a heat insulation shell (14) is fixedly installed on the outside of the water pipe (44); the inlet pipe (45) extends out of the heat insulation shell (14); and one end of the inlet pipe (45) extending out of the heat insulation shell (14) is fixedly connected to the cleaning agent storage box; A retaining ring (37) is fixedly installed inside the cleaning plate (3), and a plurality of air holes are formed on the retaining ring (37); During operation, when the internal combustion engine starts to work, the internal combustion engine generates high-temperature exhaust gas. At this time, the high-temperature exhaust gas flows into the interior of the main body (1) through the intake pipe (11). Since the slider is slidably installed in the slide groove (13), and a cleaning plate (3) is fixedly installed at one end of the slider (35), when the high-temperature exhaust gas flows into the interior of the main body (1), the high-temperature exhaust gas flows downward along the main body (1) and squeezes the cleaning plate (3), causing the cleaning plate (3) to flow downward, driving the push rod (34) on the cleaning plate (3) to move downward and contact the through hole (33) on the catalyst carrier plate (8) near the exhaust pipe (12). Under the pressure of the high-temperature exhaust gas, the push rod (34) extends into the interior of the through hole (33), and removes the carbon deposits and impurities accumulated in the through hole (33). The high-temperature exhaust gas is ejected from the interior of the second through hole (33). At this time, since the cleaning plate (3) is provided with an exhaust hole (31), the high-temperature exhaust gas will enter the cleaning plate (3) along the exhaust hole (31) while squeezing the cleaning plate (3). Then, the high-temperature exhaust gas flows into the interior of the push rod (34) along the through hole (32). While the push rod (34) pushes out the carbon deposits and impurities, the high-temperature exhaust gas also flows out from the top of the push rod (34) and directly contacts the catalyst coating inside the second through hole (33) to react, thereby achieving the conversion of the exhaust gas. The cleaning plate (3) is fixedly installed between the slider (35). Therefore, when the cleaning plate (3) moves downward, the slider (35) is driven to move downward together, so that the spring (36) below the slider When the high-temperature exhaust gas is compressed and flows out along with the push rod, the squeezing force of the high-temperature exhaust gas on the cleaning plate (3) is reduced, and the spring begins to recover its deformation upward, pushing the cleaning plate (3) to move upward, and the high-temperature cleaning agent is introduced into the cleaning agent tube (41). At this time, the high-temperature exhaust gas enters the inside of the intake pipe (11) and squeezes the push plate (53), pushing the push plate (53) to move downward, driving the connecting rod (43) to move downward together, so that the piston (42) moves downward in the cleaning agent tube (41) to the turning point of the cleaning tube, and the push plate (53) moves downward and drives the baffle plate (52) to move downward together, so that the baffle plate (52) contacts the push rod three (57). At this time, the baffle plate (52) is pushed open by the action of the push rod three (57) and deflected upward. At this time, the push plate (53) The spring three (55) will be compressed. Since the baffle plate (52) is fixedly mounted on the rotating shaft (58), when the baffle plate (52) rotates upward, it drives the rotating shaft (58) to rotate together, and then drives the ratchet wheel (7) to rotate together, so that the ratchet wheel (7) and the clamping block (541) are in contact and locked, so that the liquid inlet pipe (421) on the piston (42) is always at the turning point of the cleaning agent pipe (41), so that the high-temperature cleaning agent can flow into the water inlet hole (4) through the liquid inlet channel (421) on the piston (42). When the high-temperature exhaust gas flows into the interior of the main body (1) through the through hole three on the push plate (53), the high-temperature exhaust gas extrusion on the push plate (53) will be reduced, and the compression of the spring three (55) will decrease and begin to recover upward.The push plate (53) is pushed to move upward, thereby driving the piston (42) to move upward so that the liquid inlet channel (421) of the piston (42) is separated from the turning point of the cleaning agent pipe (41). When the cleaning plate (3) moves downward under the action of the high-temperature exhaust gas, the push rod (34) moves downward together with the cleaning plate (3). Since an irregular metal wire is fixedly installed outside the push rod, and the metal wire contacts the inner wall of the through hole (33), when the push rod (34) moves into the through hole (33), the irregular metal wire moves into the through hole (33) together with the push rod (34). When the exhaust gas squeezes the cleaning plate (3) downward, the cleaning plate (3) moves downward, thereby driving the push rod (21) to move downward together, so that the scraper (22) fixed to the push rod (21) moves downward together with the push rod (21). When the high-temperature cleaning agent passes through the cleaning plate (3), the cleaning plate (3) moves downward together with the push rod (21). When the high-temperature cleaning agent flows into the water pipe (44) through the inlet pipe (45), the high-temperature cleaning agent will flow in the water pipe (44) and flow to the inlet of the cleaning pipe, so that the high-temperature cleaning agent preheats and insulates the inside of the main body (1), thereby ensuring that the temperature inside the main body (1) is at a relatively high temperature. The heat-insulating shell (14) further isolates the heat of the high-temperature cleaning agent flowing in the water pipe (44). When the high-temperature exhaust gas flows into the cleaning plate (3) through the exhaust hole (31), the cleaning agent flowing in through the water inlet hole (4) will flow into the inside of the retaining ring (37) because the retaining ring (37) is fixedly installed inside the cleaning plate (3). The exhaust gas flows into the outside of the retaining ring (37) inside the cleaning plate (3) through the exhaust hole (31), squeezes and blocks the cleaning agent in the retaining ring (37), and promotes the cleaning agent to flow downward into the top rod (34).
