The Piston Ring Set is used in the Lincoln Mark VIII vehicles as part of the engine system to optimize the performance due to the sealage of the combustion chamber to reduce or prevent gas leakage and to increase the fuel-air mixture for burning. This set typically consists of three rings per piston: Two compression rings that provide a good sealing and one oil control ring which controls oil consumption by wiping the oil back to the crank case. Made from cast iron or steel the Lincoln Mark VIII Piston Ring Set is intended to provide minimum friction while at the same time sealing well which is important in the efficiency and lifespan of the engine. Through the years, there are different cross-sectional shapes and coatings to enhance the strength and capabilities of these rings. These parts require proper lubrication, lack of lubrication may result to engine problems such as ring binding.
