PSZ Ceramics for Adiabatic Engine Components

Partially stabilized zirconia is an insulating ceramic which offers high strength, high thermal expansion, and wear resistance. Low thermal conductivity provides the required insulation, high strength improves reliability, and high thermal expansion provides a simple means of attachment for ceramic engine components. Pistons, cylinder liners, and cylinder heads have been insulated with PSZ and engine tested in an adiabatic diesel engine.
