Product Characteristics



Product Principle
The piston ring also plays an important role in lubrication control. A thin lubricating oil film is formed between the piston and cylinder wall, reducing direct contact between metal surfaces, thereby reducing friction loss and wear.
Product Operation
When it comes to piston ring operation, it is generally carried out during engine maintenance or replacement of piston rings. Firstly, disassemble the cylinder head and cylinder block of the engine. Then, remove the crankshaft and connecting rod assembly so that the piston can be removed.
The piston ring is generally composed of several rings, closely connected on both sides. Common structures include oil rings, oil control rings, and upper and lower spiral grooves. The piston rings with different structures undertake different functions, such as sealing the cylinder, conducting heat, lubricating, etc.
