Piston Ring C05AL-10 SHANGCHAI

Product Features

• Structure: A complete set including a chrome-plated top compression ring, a taper-faced second compression ring, and a three-piece oil control ring.

• Performance: Provides reliable combustion sealing, precise oil control to reduce consumption, and efficient heat transfer from the piston to the cylinder liner.

• Design: Directly interchangeable with OEM rings, ensuring a precise fit with the piston grooves and cylinder liner.

Core Functions

1.Combustion Chamber SealingThe primary function is to create a reliable seal between the piston and cylinder liner, preventing combustion gases from leaking into the crankcase. This maintains optimal cylinder compression pressure, ensuring maximum engine power output and fuel efficiency.

2.Oil Consumption ControlThe second compression ring and oil control ring work together to scrape excess oil from the cylinder wall, leaving only a thin lubricating film. This prevents oil from entering the combustion chamber, reducing oil consumption and minimizing carbon deposits.

3.Heat TransferThe piston rings act as the main heat transfer path from the piston to the cylinder liner. They dissipate high temperatures from the piston crown to the liner, which is then cooled by the engine coolant, preventing piston overheating and deformation.

4.Dynamic AdaptationThe rings use their inherent elasticity to maintain constant contact with the cylinder wall during high-speed reciprocating motion. This ensures a stable seal even under dynamic operating conditions such as high engine speeds and heavy loads.
