Overview

Piston rings play a very important part in internal combustion engines. They must absorb the combustion pressure, cool the piston, keep the oil in the crankcase and provide a film of oil on the cylinder wall. Most modern 4-stroke engines are usually fitted with three piston rings per cylinder. The first ring holds back the combustion gases. The second ring helps to hold back combustion gases and also scrapes the oil downward. The third ring holds the oil where it needs to be. Types include Compression rings (Rectangular, Taper faced, Internally bevelled, Internally stepped, Ridge dodger, Keystone, Half-keystone, Taper faced scraper, Barrel faced, L-ring), Scraper rings (Napier, Taper faced napier), and Oil control rings (Oil control, Double-bevelled oil control, Coil ring-loaded slotted oil control, Coil ring-loaded bevelled-edge oil control, 3-piece oil control).
