● Special water cooled valve, special alloy material, unique degassing structure at the stem, reducing carbon deposition, effectively improving the service life of the intake and exhaust valves;

● Water cooled and air cooled dual heat dissipation cylinder body structure, allowing lower engine temperature and more stable performance;

● The use of a special oil pump for powder metallurgy gears improves the high temperature and oil resistance of the oil pump gears, making the engine lubrication performance more stable;

● The cylinder head refers to the water cooled water ring structure and adds a cooling oil passage. The cylinder head and cylinder head cover are designed with large blades, with good heat dissipation efficiency. The engine cylinder temperature is 6-8 ℃ lower than that of the ordinary cylinder head.
