What Types Of Rings Other Than Piston Rings Are Available For Automotive Sector?

Automotive industry is among largest industries that possess a variety of components and spares for automobile and applications. In this article, we will discuss the rings offered by suppliers. There are three types of rings that exporters and manufacturers have in their store/ unit. Each of the three rings in a set is a specialist and carries different combination of materials, shapes, heat treatment, and/ or surface coating to perform its assigned function in an optional process. Lubrication piston rings are of two kinds.

Types of Piston Rings-

There are distinct combinations of numbers of such rings that fit well in the engine design. Some engines need 2, 3, 4, 5 or 6 piston rings each piston.

What is the Purpose of Piston Rings?

Piston rings are intended to perform three principle functions in engines-

  1. Seal off the combustion chamber from the crankcase
  2. Transfer heat absorbed by the piston in the process of combustion in order to cool down the cylinder walls.
  3. Limit and control oil consumption

The top ring is the upper compression ring that operates under severe conditions with respect to mechanical and thermal loading. It’s main function is to prepare a air-tight barrier between the piston and cylinder wall to seal the combustion chamber. These are also used to transfer heat to the cooled cylinder walls like a bridge.

Second ring is the lower compression ring that works together with top ring to seal the combustion chamber and dissipate heat to the cylinder walls. These are also used for controlling oil consumption.

Oil control rings are third kind of rings that regulate and limit oil consumption. They expel excess lubricating oil from the cylinder walls and push it to the crankcase. Engineers have intended oil control rings in order to provide a thin oil film to ensure lubrication of piston ring.
