1；Top shape: flat top (compact combustion chamber), concave top (adjustable compression ratio), convex top (two-stroke specific), which needs to be matched with the cylinder head flow channel to achieve efficient combustion.
2；Asymmetric design (offset 1-2mm) reduces knocking noise, and pin hole retaining rings prevent axial movement
3；Aluminum silicon alloy (lightweight+thermal conductivity) or cast iron (wear resistance), some high-performance pistons use forging technology to enhance grain structure.
4；Skirt design: Adopting a variable elliptical barrel structure to compensate for thermal deformation, the cold state is pre processed into an elliptical shape perpendicular to the piston pin, ensuring uniform running clearance.
5；The instantaneous temperature at the top can reach 2500K, and the working area is 600-700K, requiring special heat-resistant coatings or alloy materials.
