In the engines of automobiles, ships, or construction machinery, the piston is undoubtedly the core component. Its main function is to withstand the gas pressure generated by the combustion of fuel in the cylinder, and transmit this pressure to the crankshaft through the piston pin and connecting rod, converting the linear reciprocating motion of the piston into the rotational motion of the crankshaft, thereby outputting power. In addition to power transmission, the top of the piston also forms a combustion chamber together with the cylinder head.

　　The working environment of pistons is extremely harsh. It directly withstands the instantaneous high-temperature gas impact of over 2500K, with a top pressure of 3-5 MPa in gasoline engines and 6-9 MPa in diesel engines. At the same time, the piston moves back and forth at a high speed of 8-12m/s inside the cylinder, and bears a huge inertial force. Under such high temperature, high pressure, high speed, and difficult lubrication conditions, the piston must have extremely high thermal strength and wear resistance. Therefore, modern pistons typically use aluminum alloy materials and are designed with complex structures to cope with thermal expansion and mechanical stress, ensuring smooth engine operation.
