Method and Apparatus for Reduced Oil Consumption and Oil Deterioration in Reciprocating Engines

Abstract: 

A method and apparatus for reducing oil consumption and oil deterioration in a reciprocating engine. The engine is provided with ceramic rings and ceramic cylinder linings. Minimal oil lubricant is adsorbed on the surface layer of the rings and liners to form a lubricating boundary-film on the rings and linings. Excess oil lubricant is restricted from entering the piston ring/cylinder lining region to preclude the formation of a hydrodynamic, full film lubricant layer between the rings and linings. Several engine designs are disclosed.
