Packaging quantity:1set

• Sealing and pressure maintenance: The piston, piston ring, and cylinder sleeve are tightly matched, effectively sealing the combustible mixture inside the cylinder, ensuring combustion pressure, and reducing power loss.
• Thermal conduction cooling: The heat absorbed by the piston can be transferred to the cylinder sleeve through the piston ring, and then dissipated to the outside, avoiding deformation and failure of the piston due to high temperature.
• Wear resistant and wear-resistant: The inner wall of the cylinder sleeve has been specially treated and combined with the wear-resistant material of the piston ring, which can withstand high-frequency reciprocating friction and improve the service life of the components.
• Strong adaptability: The complete design has a high degree of matching, can directly replace aging parts, is easy to install, does not require additional calibration, and reduces maintenance difficulty.
• Optimizing power: Good cylinder sealing and smooth piston movement can improve fuel combustion efficiency, making engine power output smoother and stronger.
