Efficient oil scraping and oil distribution function: The oil ring is responsible for controlling the amount of lubricating oil on the cylinder wall. Excessive or insufficient lubricating oil can affect engine performance. This oil ring adopts advanced structures such as slotted oil rings or steel belt combination oil rings, which have excellent oil scraping and oil distribution capabilities. The side of the slotted oil ring is parallel, with two contact rings and a return hole. When the piston descends, it can scrape off excess lubricating oil on the cylinder wall and return it to the oil pan through the return hole; When the piston is moving upwards, a thin oil film can be evenly distributed on the cylinder wall to ensure good lubrication of the piston, cylinder wall, and gas ring. The steel strip combination oil ring is composed of a lining ring and two scraper rings. The lining ring provides radial elasticity, making the scraper ring tightly adhere to the cylinder wall, resulting in a more significant oil scraping effect. At the same time, it can effectively prevent lubricating oil from entering the combustion chamber, reduce carbon deposition, and maintain the cleanliness of the engine interior.
Stable structure and reliable performance: The structural design of the oil ring fully considers the complex stress conditions during engine operation, ensuring stable oil scraping and oil distribution performance during high-speed reciprocating motion. The lining ring and scraper ring of the steel strip combination oil ring are tightly matched and have good flexibility, which can adapt to the small deformation of the cylinder wall and ensure the consistency of the oil scraping effect. The manufacturing accuracy of slotted oil rings is extremely high, and the dimensional tolerances of each part are strictly controlled to ensure that the oil return hole will not be blocked and the oil scraping blade will not wear out during long-term use, maintaining stable oil control ability and providing strong support for the reliable operation of the engine.
Strong wear resistance and fatigue resistance: During engine operation, piston rings need to withstand high temperatures, high pressures, high-speed friction, and complex mechanical stresses. This piston ring is made of high-quality high-strength alloy material, which has excellent wear resistance and fatigue strength. In high temperature environments, the material's organizational structure is stable and not easily softened or deformed, effectively resisting wear. At the same time, through a special heat treatment process, the internal strength and toughness of the material have been improved, which can maintain good mechanical properties under frequent alternating loads, and is not prone to fatigue fracture and other problems, ensuring that the piston rings can still work reliably under long-term high load operation of the engine and extending the service life of the engine.
Good thermal conductivity and heat dissipation performance: During the working process, the piston ring needs to quickly transfer a large amount of heat absorbed by the piston to the cylinder wall to achieve effective cooling of the piston. The piston ring is made of materials with high thermal conductivity, and through optimized structural design, the contact area with the cylinder wall is increased, thereby improving the thermal conductivity efficiency. When the engine is running at high load, it can timely dissipate the heat of the piston, prevent the piston from being damaged due to overheating, maintain the normal operating temperature of the engine, and ensure the stability and reliability of the engine. For example, when the vehicle climbs slopes or drives at high speeds for a long time, the piston rings can quickly transfer heat, avoiding engine overheating and ensuring stable power output.
High strength alloy material: The piston ring body is made of high-quality high-strength alloy as the base material. This alloy has excellent comprehensive performance, not only possessing high strength and good toughness, which can effectively resist mechanical and thermal stress impacts during engine operation, but also excellent wear resistance. During long-term high load operation of the engine, the piston rings frequently come into contact and rub against the cylinder walls, piston ring grooves, and other components. High strength alloy materials can effectively resist wear, ensure the long-term stability of the structural dimensions of the piston rings, guarantee the accuracy and reliability of engine power transmission, greatly extend the service life of the piston rings, and reduce the maintenance and replacement costs of the engine.
Advanced surface treatment technology: In order to further enhance the performance and durability of the piston ring, its surface has been specially treated. Advanced processes such as nitriding, chrome plating, and phosphating are used to form a hard, smooth, and self-lubricating coating on the surface of the piston ring. Nitriding treatment forms a highly hardened nitride layer on the surface of the piston ring, improving its wear resistance and corrosion resistance; The chrome plating layer is finely crystallized, compact, and smooth, with a hardness of over 850HV and excellent wear resistance. Its criss crossing micro crack network is conducive to storing lubricating oil and reducing friction coefficient; Phosphating treatment generates a layer of phosphating film on the surface of the piston ring, which not only prevents rust but also improves the initial running in performance of the ring. These advanced surface treatment processes ensure that piston rings maintain good performance throughout long-term use.
