INTRODUCTION. Piston ring is one of the most important part of the Deisel/Petrol engines.It is an open-ended ring that fits into a groove on the outer diameter of a piston in a reciprocating engine such as an internal combustion engine or steam engine. The principal function of the piston rings is to form a seal between the combustion chamber and the crankcase of the engine. The goal is to prevent combustion gases from passing into the crankcase and oil from passing into the combustion chamber The three main functions of piston rings in reciprocating engines are: 1. Sealing the combustion/expansion chamber. 2. Supporting heat transfer from the piston to the cylinder wall. 3. Regulating engine oil consumption. During the compression and power strokes, the compression ring seals the combustion gases and prevents blow-by. Although blow-by is not completely eliminated it is kept to an acceptable limit. During the compression and exhaust strokes the cylinder walls are lubricated with oil by throw off from the connecting rod bearings. Excess oil is wiped off by the piston rings. Not only does the oil ring have the responsibility of wiping the excess oil off the cylinder walls, but the job is also shared by all of the rings, leaving a fine layer of oil on the wall to provide lubrication for the following ring. As rings wear, the ability to perform these functions is decreased resulting in oil consumption and blow-by. When this happens it is time for a new set of rings. MARKET POTENTIAL Piston ring is the one of the most replaceble part of the diesel/petrol engines.It has great demand in the replaceble market as well as in new engines market.For the last few years there is
