Lower fuel consumption: reduces combustion leaks and improves fuel economy. Wear resistant and drag reducing: The inner wall oil storage structure reduces piston ring friction and minimizes power loss. Better emissions: Improved combustion efficiency, reduced unburned mixture emissions, in compliance with environmental standards. Smooth operation: Accurate cylinder liner guidance reduces piston side sway, lowers vibration, and enhances operational comfort. Reliable sealing: The piston ring is matched with the cylinder liner to reduce blowby, maintain optimal compression, and ensure more stable power output., Manufacturer: OZZSGSD
