Abstract: A ceramic/metallic, low polluting, long life, high performance, two-cycle gasoline engine that requires no oil lubrication. This engine eliminates the need for oil lubrication by: a) incorporating advanced ceramic materials, such as silicon nitride for critical engine components, b) employing the use of gasoline as well as the products of combustion of gasoline as lubricants for some critical surfaces, and c) engineering design approaches for critical engine components and assemblies. The elimination of the need for oil lubrication allows the engine to produce far less pollutants than conventional two-cycle engines.
