What is two type of piston ring?
There are compression ring and oil control ring
What piston ring provides a controlled film of oil to lubricate the compression ring?
oil control ring
How do you install piston rings?
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.
Does each piston have two compression rings and one oil ring true or false?
Normal piston have 2 compression rings and a 3 piece oil ring. Some aftermarket rings have a 2 piece zero-zap second compression ring to reduce blow-by.

What is the top ring nearer to the piston crown?
compression rings.. while the bottom ring is known as oil ring .
What is the position of piston ring?
Generally in grooves near the top of the piston. The compression rings, near the top and the oil rings at the bottom of the top. The ring gaps are staggered.
Does the bottom piston ring on a four-cycle engine help control excessive compression?
No, the bottom ring is the oil ring. It wipes excess oil off the cylinder wall.
In a typical automotive engine the piston contains compression rings?
Yes. That is a true statement.
Why would and engine lose compression?
Valve, valve spring, piston, piston ring, cylinder wall, head, headgasket, diluted oil, stuck injector,
When a piston has three ring the bottom ring will be?
Most commonly the bottom ring will be the Oil Controlring.(Control added by amclaussen.)Oil control ring is correct. It is used to keep the cylinder lubricated as the piston goes up and down. The first two top rings are for compression. However, the 2nd from the top ring is also a wipper ring. Used to keep oil from getting into the combustion chamber.(~Decker)
Why is it necessary to stagger piston rings?
To prevent oil getting by the oil ring and compression past the others. Also, if they were in line, it would tend to make a groove in the cylinder wall.
