Piston ring processing features

Piston ring is the key component of engine, its function depends on the combined action of gas pressure, elastic force, inertia force and friction force, forming axial, radial and rotary motion. However, irregular movements (such as axial vibration, radial oscillation and twisting) can easily lead to seal failure and abnormal wear.

Modern design by optimizing structural parameters:

① Control ring height to reduce axial float,

② Adjust radial elastic distribution to suppress vibration,

③ Special surface treatment reduces friction coefficient.

At the same time, dynamic simulation technology is used to balance the sealing demand and motion stability, effectively improve the efficiency of gas seal by 15%-20%, and extend the service life by more than 30%. The core design concept is to utilize beneficial motion characteristics, suppress harmful vibration modes, and achieve synergistic improvement of power and reliability.

The piston ring has three main functions

  1. Air tightness: reduce gas leakage through elastic sealing (leakage rate <5%), improve thermal efficiency and prevent parts from seizing;
  2. Oil control: accurately scrape off excess lubricating oil (residual oil film 3-5μm), balance lubrication and oil consumption, and avoid carbon deposits;
  3. Support: bear 70% of the lateral force of the piston, maintain movement stability, and prevent cylinder wear.

Factory design optimizes the ring tension and surface treatment technology to achieve a seal life of more than 200,000 kilometers, while reducing friction loss by more than 15%, ensuring efficient and reliable operation.
