1, good thermal conductivity, high temperature and high pressure, corrosion resistance, have good heat dissipation capacity, heating area is small.
2, should have smaller friction coefficient between the piston and the piston wall.
3, the temperature change, the size and shape change, and to keep the minimum clearance between the cylinder wall.
The piston is in the automobile engine cylinder for reciprocating motion.Basic structure can be divided into the top, the head and piston skirt.Of the piston at the top is the main part of the combustion chamber, the shape related to the chosen form of combustion chamber.With flat-top piston of the gasoline engine, its advantage is endothermic area is small.
