Technical Field

[0002] The EGR valve is a mechatronic product installed on a gasoline engine to control the amount of exhaust gas recirculation fed back to the intake system. The EGR valve can allow a certain amount of exhaust gas to be mixed with fresh air and then returned to the cylinder for recirculation, thereby reducing the combustion temperature and combustion speed in the cylinder and further reducing the emission of nitrogen oxides (NOX).

[0003] Currently, when using an EGR valve, part of the exhaust gas generated after cylinder combustion directly enters the internal cooling end of the EGR valve. After cooling, it is mixed with the external fresh air and returned to the cylinder for recirculation. However, before cooling, the exhaust gas after combustion in the cylinder will carry a certain amount of fine impurities. These impurities can easily contaminate the interior of the EGR valve during repeated circulation, and the fine impurities will also cause secondary pollution to the interior of the cylinder when they flow back into the cylinder along with the mixed air.

After cooling, the exhaust gas is discharged through the exhaust pipe and mixed with fresh air before re-entering the interior of the automobile engine through the engine's air intake. In addition, a portion of the exhaust gas from the automobile engine is filtered by the air filter component before entering the cooling pipe. During the filtering process, the feedback component assists the air filter component, and the control component controls the operation of the entire device. Step S2: When the control component is working, the coil is wound around the outer surface of the iron core. By turning the coil on and off, the iron core generates magnetic attraction, thereby adsorbing the valve core to control the opening and closing of the outlet pipe and the working condition of the air filter component; Step S3: When the air filter assembly and the feedback assembly are working, the valve core can be driven to slide toward one end of the valve housing, and the filter cartridge can be driven to slide toward the outside of the cylindrical groove during the sliding process of the filter cartridge.

Step S4: When the cooling circulation component is working, the gas entering one end of the cooling pipe is cooled through the air distribution pipe and then enters the other end, and then flows out from the air outlet pipe. Cooling water is injected into the interior of the cooling pipe from the water inlet pipe. The cooling water cools the air distribution pipe inside the cooling pipe and then flows out from the water outlet pipe. The cooling water flows in an S shape along the first guide plate and the two second guide plates inside the cooling pipe, thereby ensuring that the cooling water fully cools the air distribution pipe.

After cooling, it will be discharged through the outlet pipe and mixed with fresh air before re-entering the interior of the car engine through the air intake of the engine. In addition, a portion of the gas exhausted by the car engine will be filtered by the air filter component before entering the cooling pipe. During the filtering process, the feedback component will assist the air filter component in working, and at the same time, the operation of the entire device will be controlled by the control component. 2. In the present invention, when the control component is working, the coil is wound on the outer surface of the iron core. By turning the coil on and off, the iron core generates magnetic attraction, thereby adsorbing the valve core to control the opening and closing of the outlet pipe and the working condition of the air filter component; 3. In the present invention, when the air filter assembly and the feedback assembly are working, the valve core can be driven to slide toward one end of the valve housing to the outside of the cylindrical groove during the sliding process of the filter cartridge. The threaded ring can be driven to rotate during the sliding process of the filter cartridge. The rotation of the threaded ring drives the nylon ring to rotate through the support rod, thereby driving the brush to clean the outer surface of the filter cartridge. At this time, the air vent is connected to the exhaust filter port, the bent air duct is connected to the side port, the air outlet is located on the inside of the protruding nozzle tube, and the mesh filter port is located on the inside of the supporting ring. Therefore, during the cleaning process, the air flow can enter the interior of the filter cartridge from the side port and the bent air duct, and flow out from the inside of the filter cartridge to the outside. The brush can be used to remove fine impurities attached to the outer surface of the filter cartridge. The fine impurities enter the filter cover from the exhaust filter port along with the gas, and are finally filtered by the filter sleeve and discharged to the outside. 4. In the present invention, when the cooling circulation component is working, the gas entering one end of the cooling pipe is cooled through the air distribution pipe and then enters the other end, and then flows out from the air outlet pipe. Cooling water is injected into the interior of the cooling pipe from the water inlet pipe. The cooling water cools the air distribution pipe inside the cooling pipe and then flows out from the water outlet pipe. The cooling water flows in an S shape along the first guide plate and the two second guide plates inside the cooling pipe, thereby ensuring that the cooling water fully cools the air distribution pipe.

In addition, a portion of the exhaust gas from the automobile engine is filtered by the air filter component before entering the cooling pipe 1. During the filtering process, the feedback component assists the air filter component in working, and the control component controls the operation of the entire device. Step S2: When the control component is working, the coil 20 is wound around the outer surface of the iron core 19. By turning the coil 20 on and off, the iron core 19 generates a magnetic attraction, thereby adsorbing the valve core 14 to control the opening and closing of the outlet pipe 6 and the working condition of the air filter component; Step S3: When the air filter assembly and the feedback assembly are working, during the process of the valve core 14 sliding toward one end of the valve housing 3, the filter cartridge 38 can be driven to slide toward the outside of the cylindrical groove 26. During the sliding process of the filter cartridge 38, the threaded ring 34 can be driven to rotate. The rotation of the threaded ring 34 will drive the nylon ring 36 to rotate through the support rod 35, thereby driving the bristles 37 to clean the outer surface of the filter cartridge 38. At this time, the air vent 42 is connected to the exhaust filter port 31, the bent air duct 45 is connected to the side port 28, and the air outlet 39 is located on the inner side of the protruding nozzle tube 33, and the mesh filter port 40 is located on the inner side of the support ring 23. Therefore, during the cleaning process, the air flow can enter the interior of the filter cartridge 38 from the side port 28 and the bent air duct 45, and flow out from the inside of the filter cartridge 38 to the outside. The bristles 37 can be used to remove fine impurities attached to the outer surface of the filter cartridge 38, and the fine impurities enter the filter cover 7 along with the gas from the exhaust filter port 31, and are finally filtered by the filter sleeve 9 and discharged to the outside. Step S4: When the cooling circulation component is working, the gas entering one end of the cooling pipe 1 is cooled through the gas distribution pipe 11 and then enters the other end, and then flows out from the gas outlet pipe 6. The cooling water is injected into the interior of the cooling pipe 1 from the water inlet pipe 5. The cooling water cools the gas distribution pipe 11 inside the cooling pipe 1 and then flows out from the water outlet pipe 4. The cooling water flows in an S shape inside the cooling pipe 1 along the first guide plate 12 and the two second guide plates 13, thereby ensuring that the cooling water fully cools the gas distribution pipe 11.
