Guidelines for design of piston rings

Materials of Piston Rings are usually made of grey cast iron and in some cases, alloy cast iron. Grey cast iron has excellent wear resistance. It also retains the spring characteristic at high temperatures. In some cases, piston rings are chromium-plated to reduce wear.
(ii) Number of Piston Rings: There are no strict rules for deciding the number of compression rings. The number of compression rings in automobile and aircraft engines is usually between 3 to 4. In stationary diesel engines, 5 to 7 compression rings are used. The number of oil scraper rings is usually between 1 to 3.
