The cylinder block adopts cast iron and lattice structure to enhance the strength of cylinder block; arrange observation window beside the engine body to replace connecting rod and connecting rod bearing more conveniently. The cylinder block adopts single cylinder head and reasonable design of cooling water chamber to cool the cylinder head more completely.
1. Lubrication system is designed by European top design team.
2. flow oil pump could support higher engine oil pssure (Rate point reaches 0.62MPa)
3. There is hand pss engine oil pump installed on engine body, which could p-lubricate the engine to reduce starting resistance
4. Bypass engine oil centrifugal filter improves quality of lubricating oil.
