To keep the piston from melting down, heat must be transferred out through the piston rings to the cylinder walls and ultimately into the cooling jacket. Today's engines tend to run hotter than ...

It's a well-known fact that piston ring gaps represent an area of pressure loss in a running engine. It has been found that minimizing end gap under operating conditions offers a measurable power ...

Pistons reciprocate inside the cylinders of an internal combustion engine. The outer diameter of the piston is slightly smaller than that of the cylinder liner, enabling it to move up and down with ...

The problem: Piston rings may rotate and align in certain Honda cars. If this happens, uncontrolled oil burning may occur inside the engine, causing it to misfire. This may be due to faulty piston ...

Piston ring grooves serve a larger purpose than simply supporting the rings. They impact combustion sealing, oil control, friction, and many more engine attributes. Wiseco is a world leader in piston ...

SAE Transactions, Vol. 97, Section 2: JOURNAL OF MATERIALS (1988), pp. 393-402 (10 pages) In current designs of the automotive (kinematic) Stirling engine, the piston rings are made of a reinforced ...

If asked what you wanted for piston rings in your engine build, would you know how to answer? Piston rings have the most important job in your engine. We will get arguments on this one because there ...

Presumably that you want to replace the worn out piston rings of a Toyota VVTi engine, you’ll need to know how to correctly put the new ones in place. The hardest part is to reach the piston rings ...
