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 should you do when a compression test reveals that compression is below average?
If the difference between the high and low reading is within 10%, it is withing normal specification. If more than 10%, try squirting oil into the low cylinder and retest, if compression comes up , this indicates a bad ring, if not indicates problem is a bad valve.
What is the top ring nearer to the piston crown?
compression rings.. while the bottom ring is known as oil ring .
After replacing valves and rings in my 6.5 Briggs and stratton it smokes real bad What is my problem?
you should have three rings, top ring is the compression ring, second ring seperates the compression ring with the third ring which is the oil ring. check to see if the gaps in all three rings are staggerd if not then you are getting oil blow bye. did you seat your new valves, if not then you may also be getting oil blow bye through the small gap in between the valves and valve seats.
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.
Does 2 stroke engine contain oil ring?
no useally just two compression rings , since there is no crankcase oil to control and since the oil is part of the fuel mix a oil control ring is not needed
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.
