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.
