The Piston Ring in GMC Jimmy automobiles play the important function of closing the combustion chamber so as to aid the burn of the fuel-air mixture and limit the emission of gases and the consumption of engine oil. These rings normally employ cast iron or steel and are meant to be used in a way that they will produce low friction but at the same time seal efficaciously which is important in the achievement of high efficiency and durability of the engine. Some of the Piston Rings used in GMC Jimmy over the years include the modern thinner Piston Rings with 1mm or 2mm thickness that enables enhanced sealing besides improving the coefficients of friction. These enhancement enables improved compliance to the cylinder bore as well as improved oil retention. The Piston Rings are usually coated with plasma-moly or chrome to enhance heat and wearing resistant which is enhancing the durability of the engine performance on the Gas Machinery Company GMC Jimmy.
