مميزات خاصة

The friction coefficient between the piston and the piston wall is small, which can reduce the energy loss and improve the engine efficiency
Dimensional stability: When the temperature changes, the size and shape changes are small, and the gap with the cylinder wall can be maintained at a minimum
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.
