    Abstract: A method and apparatus for insulating the exhaust passage of an internal combustion engine is disclosed. A three-zone liner assembly is provided with an outer zone comprised of a room temperature vulcanizing silicone sleeve, an inner zone comprised of a stamped and seam welded high strength Al-Cr-steel alloy, and an intermediate zone consisting of a ceramic wool mat. The liner assembly is supported or enclosed within a mild carbon sheet metal sleeve which in turn may be bonded to the engine passage wall by use of a room-temperature-vulcanized silicone if of the insert type, or by fusion bonding during casting if of the cast-in-place type.

    Abstract: A thermal barrier and wear coating having high strength, low conductivity, a low thermal expansion coefficient and good adhesion qualities, where the wear coating is self-lubricating and has high temperature resistance, a hard wear resistant matrix, a low coefficient of friction and is easy to machine to a smooth surface. The thermal barrier is applied to the internal engine cylinder surface to reduce the heat rejection and thus reduce the need for air or liquid cooling. The self-lubricating wear coating is applied over the thermal barrier to prevent contact between the moving engine parts and the thermal barrier. The wear coating has a low friction coefficient so that it does not generate substantial additional heat and is self-lubricating to withstand temperatures up to 900.degree. C.
