The Piston Ring found in the GMC Envoy cars contributes very much in sealing the combustion chamber and in burning the fuel and air mixture and in addition it controls the outflow of gases and the consumption of engine oil. These rings, normally integrant of cast iron or steel, are built to minimize friction while at the same time providing adequate sealing and this plays a big role in the efficiency and durability of the engines. Throughout the year, GMC Envoy has employed a number of Piston Rings, including, the new generation thin type with 1mm top and second rings as well as 2mm oil control rings. Such thin rings minimise friction and exhibit better sealing capabilities, thus offering greater oil management and variable piston profiles. Piston Rings employed in the GMC Envoy automobile is designed to work under complicated lubrication regimes, and therefore it is coated to enhance its performance.
