This prototype uses water cooling, PTFE rings, and 3D‑printed mounts to turn 200‑year‑old heat‑engine tech into a ...

The piston rings have three major roles - to seal the combustion chamber, clean the cylinder wall and create a very thin layer of oil on it in order to minimize friction. Each ring has gap, which ...

I was unwittingly amazed yesterday when I came across a video about how Clupet piston rings are made (and learned the word ‘Clupet’ at the same time). Unlike a car piston ring which is a single ring ...

Federal-Mogul Powertrain has upgraded its Goetze Diamond Coating (GDC) for piston rings, a technology used ub heavy-duty diesel engine requirements for over 10 years. The new coating, GDC60, has ...

Question There are many different beliefs about how to properly run in a new car to ensure the correct wear-in of bores/piston rings. In many cases these tips are not mentioned in the manual.
