• The pin hole of the high-load piston is designed to be a micro inner cone type or a normal stress curved type. The dimensional accuracy of the pin hole is IT4 level, and the contour accuracy is 0.003mm, which improves the bearing capacity
• The piston top and ring groove are designed to facilitate heat transfer and dissipation
• Low noise design: Optimal construction and materials reduce engine noise during operation.
• Maximum clearance control between gas ring and piston ring groove, oil ring and piston ring groove
• It reduces the wear of the internal parts of the engine and prolongs the service life of the engine
