The Ministry of Industry and Information Technology revealed that the “12th Five-Year Development Plan for New Materials Industry” will be released soon. "Planning" proposes that during the "12th Five-Year Plan" period, China's new material industry expects total output value to reach 2 trillion yuan, and carbon fiber, film materials, butyl rubber and other key varieties will be industrialized, scaled, and promote 30 key new Material varieties, the implementation of a number of demonstrations to promote the application of engineering.

Piston Ring

What is a piston ring?

Piston ring is used to insert the piston groove inside the metal ring, piston ring is divided into two types: compression ring and oil ring.

The compression ring can be used to seal the combustible mixture gas in the combustion chamber; The oil ring is used to scrape excess oil from the cylinder.


The significance of the piston ring:

Piston ring is the core component inside the fuel engine, it and cylinder, piston, cylinder wall together to complete the seal of fuel gas.

Commonly used car engines have two kinds of diesel and gasoline engines, because of their different fuel performance, the use of piston rings are not the same.

Early piston rings were formed by casting, but with the progress of technology, high-power steel piston rings were born, and with the continuous improvement of engine functions and environmental requirements, a variety of advanced surface treatment applications, such as thermal spraying, electroplating, chromium plating, gas nitriding, physical deposition, surface coating, zinc-manganese phosphating treatment, etc., the function of the piston ring is greatly improved.


Functional characteristics of piston ring:

Piston ring function includes sealing, regulating oil (oil control), heat conduction (heat transfer), guidance (support) four roles.

Sealing: refers to sealing gas, do not let the combustion chamber gas leakage to the crankcase, the gas leakage is controlled at a minimum, improve thermal efficiency.
