The advance of technology requires engines to be more efficient, weight less, and be more reliable. Common materials used for engine parts are not designed colse to their thermal limit for strength and lubrication. Additional component loading necessarily will demand a corresponding increase in component cooling. This increased cooling not only represents a thermodynamic loss that detracts from cycle efficiency but it also consumes additional engine power to operate the cooling system. A new approach to the thermal loading problem is to apply a thin layer of a ceramic insulator to combustion chamber surfaces thereby reducing heat transfer and metallic component temperature. The following document describes the results of a test program to evaluate engine performance for engines having ceramic coatings. Both spark and compression ignition performance was examined. Author
