A special oil control ring
The driving force action on the piston is called piston effort.In other words the net resultant of all the other forces acting on the piston is called piston effort.
Graphite isn't a ceramic material itself, however it can be made into a ceramic material
Gold is always going to be heavier than silver, its the amount of it in the ring that will determine the weight.
Steel.
Yes, the material, thickness and possibly style of piston ring(top ring) can be different.
As the piston moves up and down in the cylinder it also moves the piston rings up and down in the grooves. With the rings moving up and down it gradually increases the side clearence. Material is taken off from both the piston groove and the ring.
Mostly from cast aluminium.
A sumo ring is made out of a special kind of clay.
You have to disassemble the entire engine, remove the piston and check the rubber ring around that piston.
The DNJ ring spec. information, printed on each compression ring (located next to the piston ring gap), is installed facing the top of the piston for both the top (#1) and middle (#2) compression piston ring slots. The oil control ring can be installed just like any other oil control ring in the bottom (#3) piston ring slot.
a piston ring is not calibrated. You just slide the new one in place

one ring per piston, the pistons have a groove in it where the ring fits on.
It is made of metal really.
You mean a piston ring. It seals the gap between the piston and the chamber in your engine
Some of them are made of chrome molly but I'm shure there are other compositions as well.
