Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to an anti-clogging structure for automotive engine parts. Background Technology

[0002] The anti-clogging structure of automotive engine parts is an integrated auxiliary structure designed for core components such as fuel injectors, oil pumps, and thermostats that are prone to clogging due to impurities, carbon deposits, and waste materials in the engine's fuel supply, lubrication, and cooling systems.

[0003] Among them, the fuel rail, as the core component of the fuel supply system responsible for fuel distribution and flow guidance, needs to accurately deliver fuel to each injector to ensure stable engine operation. However, the existing fuel rail's flow guidance pipe structure design is relatively simple, lacking a targeted anti-accumulation and filtration structure inside. Impurities in the fuel are easy to adhere and accumulate on the inner wall of the pipe. Long-term use will not only lead to uneven fuel supply pressure and poor atomization effect of each injector, but also cause secondary contamination of the injectors by impurities, which in turn will cause problems such as engine power fluctuations and increased fuel consumption. Utility Model Content

[0004] The purpose of this invention is to provide an anti-clogging structure for automotive engine parts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging structure for automotive engine parts, including an oil delivery pipeline, and further comprising: The first flange is fixed to both sides of the oil pipeline. A guide plate is fixedly connected inside the oil pipeline. A connecting pipe is installed on one side of the first flange. A filter shell is installed inside the connecting pipe. A second flange is fixed to one side of the connecting pipe, and a limit plate is installed on one side inside the oil pipeline.

[0006] Preferably, the guide vanes are arranged in a ring array, and the number of limiting plates is two.

[0007] Preferably, a positioning plate is fixedly connected inside the oil pipeline, and a flow guide cone is fixedly connected to one side of the positioning plate.

[0008] Preferably, a filter ring is inserted into one side of the inside of the filter housing, a threaded ring is rotatably connected to one side of the filter housing, and a torsion ring is fixedly connected to one side of the threaded ring.

[0009] Preferably, the connecting pipe has limit grooves on both the front and rear sides, and the filter shell has sliders fixedly connected to both the front and rear sides.

[0010] Preferably, the surface of the torsion ring is provided with anti-slip grooves, which are arranged in an array.

[0011] Preferably, a sealing ring is fixedly connected to one side of the surface of the filter shell, and a sealing groove for use with the sealing ring is opened on one side inside the connecting pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a ring-shaped array of guide plates and cones inside the fuel pipeline to guide the fuel into a spiral flow, reducing the accumulation of impurities on the pipe wall. The filter shell and filter ring inside the connecting pipe can precisely filter the fuel, intercepting impurities and preventing secondary contamination of the fuel injectors. The filter shell is adapted to a slider and limiting groove, and with the help of threaded rings and torsion rings, it can be easily disassembled and installed, facilitating impurity cleaning. Sealing rings and sealing grooves ensure sealing performance, while limiting plates and positioning plates improve structural assembly stability. The overall structure combines flow guidance, filtration, and convenient maintenance functions, effectively solving problems such as uneven fuel supply to the fuel rail, impurity accumulation, and pipeline blockage, ensuring stable engine power and reducing maintenance costs.

The second flange 6 is fixed to one side of the connecting pipe 4. A limiting plate 7 is installed on one side inside the oil pipeline 1. The first flanges 2 at both ends of the oil pipeline 1 facilitate connection with other pipelines. The guide plate 3 is used to make the fuel flow in a spiral manner, which facilitates the flushing of the material on the inner wall of the pipe. The connecting pipe 4 is conveniently installed with the filter shell 5 on one side of the first flange 2 to collect the filtered impurities. The second flange 6 facilitates the connection and fixation between the connecting pipe 4 and other pipelines. The limiting plate 7 is used to assist the use of the filter shell 5.

[0017] The guide vanes 3 are arranged in a ring array, and there are two limiting plates 7. The positioning plate 8 is fixedly connected inside the oil pipeline 1. The guide cone 9 is fixedly connected to one side of the positioning plate 8. The positioning plate 8 facilitates the installation and fixation of the guide cone 9, and the guide cone 9 can flush the inner wall of the oil pipeline with the high-speed flowing fuel.

[0018] A filter ring 10 is inserted into one side of the filter housing 5. A threaded ring 11 is rotatably connected to one side of the filter housing 5. A torsion ring 12 is fixedly connected to one side of the threaded ring 11. The surface of the torsion ring 12 is provided with anti-slip grooves 15, which are arranged in an array. The filter ring 10 is inserted into the inside of the filter housing 5 to facilitate primary filtration of impurities. The threaded ring 11 is rotatably installed inside the filter housing 5 with the help of bearings, which facilitates the installation of the filter housing 5 inside the connecting pipe 4. The anti-slip grooves 15 on the surface of the torsion ring 12 can increase the friction of the torsion ring 12 itself, making it convenient for the operator to rotate the threaded ring 11.

[0019] Limiting grooves 13 are provided on both the front and rear sides of the inside of the connecting pipe 4. Slider blocks 14 are fixedly connected to both the front and rear sides of the filter shell 5. A sealing ring 16 is fixedly connected to one side of the surface of the filter shell 5.

[0020] Working principle: The device is fixedly connected to the fuel system pipeline through the first flange 2 on both sides of the oil pipeline 1 and the second flange 6 of the connecting pipe 4. After the fuel enters the oil pipeline 1, it is guided by the flow guide plate 3 of the annular array and the flow guide cone 9 on the positioning plate 8 to form a spiral flow, using the fluid impact force to reduce the adhesion of impurities to the pipe wall. When the fuel flows through the connecting pipe 4, the filter ring 10 in the internal filter shell 5 accurately intercepts impurities to avoid secondary contamination of the fuel injector. The filter shell 5 is limited and matched with the limiting groove 13 of the connecting pipe 4 by the slider 14. Rotating the torsion ring 12 with the anti-slip groove 15 can drive the threaded ring 11 to realize the convenient disassembly and assembly of the filter shell 5, which is convenient for cleaning impurities. The sealing ring 16 and the sealing groove 17 ensure the connection sealing. The limiting plate 7 improves the assembly stability of the filter shell 5. The whole device solves the problems of fuel pipeline blockage and uneven fuel supply through the synergistic effect of "flow guidance and anti-accumulation + filtration and interception + convenient maintenance".
