A piston ring is a metallic ring attached to the outer diameter of a heavy-duty truck piston in the internal combustion engine or steam engine. What’s more, piston rings can form a sealing barrier between the piston and cylinder wall, which prevents combustion gases under pressure from turning into the oil sump. They also manage the oil consumption by stopping the redundant oil from entering the combustion chamber and igniting. At the same time, it is important to maximize the engine power and improve the working efficiency by using proper truck piston rings.
