• Lightweight design: The density of the aluminum alloy piston is small, which can greatly reduce the mass of the piston and the inertia force of the reciprocating motion, and reduce the vibration of the high-speed engine and the engine
• Aluminum alloy piston thermal conductivity, working piston surface temperature is lower than cast iron
• 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
