The Piston Assembly is a vital component of the internal combustion engine or compressor, and its main components include the following:

Piston: The piston is the core part of the Piston Assembly, usually made of aluminum alloy or cast iron material. It moves up and down in the cylinder, using the high-pressure gas produced by the combustion of the fuel to convert thermal energy into mechanical energy. Piston designs generally include multiple channels and grooves to optimize heat dissipation and weight distribution.

Piston ring: Piston ring is located on the periphery of the piston, usually divided into compression ring and oil ring two kinds. The compression ring is responsible for sealing the cylinder and preventing combustion gas leakage, thereby improving engine efficiency; The oil ring helps control the flow of lubricating oil, preventing too much oil from entering the combustion chamber, reducing fuel consumption and emissions.

Piston pin: The piston pin is an important part of the connection between the piston and the connecting rod, which transmits the linear motion of the piston to the connecting rod through the sliding connection. Piston pins are usually made of wear-resistant materials and have a high strength to withstand the enormous force generated by the piston during high-speed movement.

Connecting rod: Connecting rod converts the linear motion of the piston into the rotating motion of the crankshaft to achieve power output. The connecting rod is designed to ensure its strength and rigidity to cope with various loads in engine operation.

Cylinder: Although the cylinder itself is not part of the piston assembly, it works closely with the piston to form a working chamber. The inner wall of the cylinder is carefully machined to reduce friction and wear, while also ensuring smooth movement of the piston.

Lubrication system: Although not a direct part of the Piston Assembly, a good lubrication system is essential to the proper operation of the piston. The lubricating oil forms an oil film between the piston and the cylinder, reducing friction, reducing wear, and helping to dissipate heat.

Each part works with each other to work together to ensure efficient operation and long-term stable operation of the engine. Maintaining these components can significantly improve engine performance and longevity.
