Piston rings - it rings with a small gap open. They are in the grooves on the outer walls of the pistons in all types of reciprocating engines (e.g. steam engines or internal combustion).

Why the need For piston rings?

1. For sealing of the combustion chamber. Compression rings significantly increase the compression. With stuck, broken or worn rings, the engine may not start or lose power.
2. To improve the heat transfer through the cylinder wall. Rings help when working the engine heat from the piston, thereby preventing overheating.
3. To reduce oil flow to the motor (in the two-stroke diesel and all diesel engine).

How does the piston rings?
piston rings
Butt (aka the castle) is located between the ends of the piston ring. When the piston is in the cylinder lock slightly compressed to several fractions of a millimetre. Is oblique (in a four-stroke internal combustion engine) and a straight line. Rings located in the grooves a so that the angle between the joints was equal to (2 rings - 180 degrees, 3 rings 120 degrees). The result is a labyrinth that reduces blowby.

Rings are the oil control and compression. Oil protects the combustion chamber from leakage of oil from the crankcase. They remove excess motor oil from the cylinder. Set oil ring below the compression. They have a through-slot. In two-stroke gasoline engine oil is not used, as the oil for the motor is burned together with fuel. Now available with either cast iron or composite steel rings with expanders in the form of springs. Composite is easier and cheaper to manufacture, so they are much more common than cast.
piston ring
Compression piston rings protect the crankcase from the gusts of gas from the combustion chamber. In a free state of the ring outer diameter greater than the internal. For this reason part of the product cut. Place the cut and called the castle. Usually one piston set not more than three such rings, for the reason that the degree of compaction of the piston is increased slightly, and the friction losses increase. On two-stroke internal combustion engine, as a rule, the two sets of rings. The cross section of most compression rings have the shape of a rectangle. The edge has a chamfer that tapers, or a cylindrical profile. When you work the engine the rings are somewhat twisted (this provides clearance in the groove), which facilitates their adjustment.
Making piston rings
The Manufacture of piston rings

Technology and manufacturing methods must provide the shape of the product, which in the free state would create the desired level of pressure in its working state. The piston ring is usually made of high strength gray cast iron, as it has good stable performance elasticity and strength, high wear resistance, excellent anti-friction properties. Also used alloying elements (special coating of porous chromium, cladding of molybdenum, sputtering in a plasma jet, ceramic coating, diamond particles), which greatly increases the thermal stability of the products.
