Piston technical requirements

Piston technical requirements

1, to have enough strength, stiffness, small mass, light weight, to ensure the minimum inertia force.
2, good thermal conductivity, high temperature resistance, high pressure, corrosion, full heat dissipation capacity, small heating area.
3, there should be a small friction coefficient between the piston and the piston wall.
4. When the temperature changes, the size and shape changes should be small, and the gap between the cylinder wall should be kept at a minimum.
5, the coefficient of thermal expansion is small, the proportion is small, with better wear reduction and thermal strength.
