At powered partial load conditions the ring pack contributes up to 25 % of the total mechanical engine friction loss, which could correspond to 4 % of fuel consumption. Therefore the challenge lies not only in reducing frictional power loss but also in mastering the thermo-mechanical and tribological loads as a result of the smoother cylinder bores, reduced lubrication, and use of alternative fuels.
Carbon-based, diamond-like Carbon coatings (DLC) are commonly used for components which come...
