Piston ring set must do three things: prevent the air/fuel mixture from escaping the combustion chamber, prevent oil from contaminating the combustion chamber, and transfer heat out from the piston to the cylinder wall and ultimately into the cooling jacket. In most cases this is accomplished by a set of three rings, classified (from top to bottom) as the top compression ring, the second compression ring, and the oil control ring.
Top Compression Ring
This is referred to as the "upper compression ring"? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
It is the piston ring that operates under the harshest conditions with respect to thermal and mechanical loads.
The main function are to seal the combustion chamber from the crankcase and transfer heat from the piston to the cylinder.
2nd Compression Ring
This is referred to as the "lower compressing ring".
The main function are to work together with the top ring in order to "seal" the combustion chamber, scrape oil and prevent it from reaching the combustion chamber.
Oil Scraper Ring
This is referred to as the "Oil control ring".
The main function are to scrapes excess lubricating oil off the cylinder wall, maintaining proper lubrication while keeping oil consumption within proper limits.
Custom tailored production according to drawings and samples of customers is within our capability.
Our engineers use computer based programs to design products, according to the operation plans and technical drawings. Welcome our customers to order customized products at any time, we will offer professional advises for your reference.
Below are some customized piston rings we produced before for our customers
The main function is to reduces friction and improved seal ability than standard cast iron. The bronze rings have good corrosion resistance and excellent thermodynamic characteristics for heat transfer.? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
The Bronze rings are available in all joint configurations. Please contact us with your dimensions and applications.
The main function is to prevent the lubricating oil in the supercharger intermediate from leaking out and the peripheral high-pressure air from entering the intermediate.
The seal rings are available in all joint configurations. Please contact us with your dimensions and applications.
The main function is to clearing the carbon deposits on the piston head. Also called "Anti-polishing rings" & "Carbon Rings". Usually used in piston head for 2 stroke and 4 stroke marine engine.
The clearing rings are available for us to producing. Please contact us with your models and applications.
