Description

Technical Field

[0001] This application relates to the field of internal combustion engine exhaust gas treatment technology, and in particular to a cylinder air replenishment valve. Background Technology

[0002] In modern industry and transportation, internal combustion engines have become core power equipment due to their efficient power output. However, during their operation, they inevitably produce a large amount of unburned and harmful substances, with carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) being typical examples. These pollutants, once released into the atmosphere, not only exacerbate the greenhouse effect and disrupt the ecological balance but also cause respiratory diseases and other health problems, posing a serious threat to human living environment and health.

[0003] To meet regulatory requirements, internal combustion engine manufacturers have continuously improved exhaust gas treatment technologies. Among these, three-way catalytic converters, selective catalytic reduction (SCR), and particulate filters (DPF) are widely used. Three-way catalytic converters use precious metal catalysts to convert harmful components in exhaust gas into harmless substances at specific temperatures. SCR technology uses a reducing agent to react with NOx to purify nitrogen oxides. DPFs are responsible for capturing particulate matter in exhaust gas. However, these technologies all have significant drawbacks. High costs, complex structural designs, and dependence on scarce precious metal catalysts greatly limit their widespread application and economic benefits. Furthermore, most exhaust gas treatment devices currently installed at the cylinder are bolted, which presents problems such as inconvenient installation and disassembly, and connection stability being easily affected by vibration.

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] Reference Figure 1-4A cylinder air supply valve includes a cylinder body 1. A cylinder tailpipe 2 is fixedly installed at one end of the cylinder body 1. A connecting pipe a3 is fixedly connected to the end of the cylinder tailpipe 2 away from the cylinder body 1. A connecting pipe b4 is provided on the side of the connecting pipe a3 away from the cylinder tailpipe 2. Several connecting parts a7 and b11 are fixedly connected to the side of the connecting pipe b4 that is close to the connecting pipe a3. The connecting parts a7 and the corresponding connecting parts b11 are externally engaged. A strong magnetic part 12 is fixedly connected to one side of the connecting part a7, and an iron part 13 is fixedly connected to the other side of the connecting part a7. In this solution, the connecting pipe a3 and the connecting pipe b4 are connected by the connecting parts a7 and b11. The snap-fit ​​of component b11, along with the strong magnetic component 12 and iron component 13 on connector a7, further enhances the connection strength on the basis of the snap-fit, forming a double stable connection. Compared with the traditional bolt fixing method, this connection method can effectively resist the vibration generated during the operation of the internal combustion engine, avoid the connection loosening due to vibration, and ensure that the exhaust valve 5 maintains a stable connection during long-term use. At the same time, the installation process does not require tedious bolt tightening. Simply align connector a7 and connector b11 and snap them together. The connection can be quickly completed by magnetic adsorption, which greatly shortens the installation time and reduces the installation difficulty.

[0025] Specifically, an exhaust valve 5 is fixedly installed at the end of connecting pipe b4 away from connecting pipe a3. A reed 14 is provided on the top of the exhaust valve 5. When the exhaust valve 5 is opened, a negative pressure is generated inside the exhaust pipe 6, and the air inlet inside the reed 14 is automatically opened, allowing outside air to enter quickly and fully mix and react with harmful substances such as incompletely burned carbon monoxide and hydrocarbons. The exhaust pipe 6 is fixedly connected to the side of the exhaust valve 5 away from the cylinder body 1. A sealing assembly is provided inside connecting pipe a3 and connecting pipe b4. The sealing assembly includes a sealing groove 10 fixedly connected to the inner wall of connecting pipe a3 and a sealing ring 9 opened inside connecting pipe b4. At the same time, the locking structure of the sealing ring 9 and the sealing groove 10 ensures the sealing of the connection between the cylinder tail pipe 2 and the exhaust valve 5, prevents gas leakage, and ensures that the incoming air can be used to react with harmful substances, thereby effectively promoting the oxidation and decomposition of harmful substances and significantly reducing the content of harmful substances in the exhaust. The sealing ring 9 and the sealing groove 10 are locked together, and the sealing groove 10 has a ring structure.

[0026] Specifically, adjacent connectors a7 fit tightly together, and the outer side of each connector a7 is fixedly connected with anti-slip texture 8 to facilitate the operation of installers and prevent the installation effect from being affected by hand slippage during the installation process. The spring 14 has several circular grooves 16 inside, and each circular groove 16 is inserted with a locking bolt 15. The spring 14 is installed above the exhaust valve 5 by means of the locking bolts 15. The setting of the locking bolts 15 facilitates the installation and disassembly of the spring 14. An air inlet is provided inside the spring 14.

[0027] Working principle: First, during the installation of exhaust valve 5, there is no need to tediously tighten the bolts. Simply align and engage connectors a7 and b11, and the connection can be quickly completed by using the strong magnetic component 12 to attract the iron component 13. This greatly shortens the installation time and reduces the installation difficulty. At the same time, the engaging structure of sealing ring 9 and sealing groove 10 ensures the sealing of the connection between cylinder tail pipe 2 and exhaust valve 5, preventing gas leakage and ensuring that the incoming air can react with harmful substances. When exhaust valve 5 is opened, negative pressure is generated inside exhaust pipe 6, and the air inlet in reed 14 is automatically opened, allowing outside air to enter quickly and fully mix and react with unburned carbon monoxide, hydrocarbons and other harmful substances.
