Metal-supported catalyst system has 0.025 mm thick walls. (Advanced in Automotive Materials).

Caption: A metal-supported catalyst system called Metalit has been developed for heat resistance and durability by Emitec, Auburn Hills, Mich. The system is composed of specially coated 0.05mm thick corrugated metallic foil that is coiled into an S design. It is heat resistant and durable, and can be placed closer to the engine for quicker heat up and faster reduction of emissions. Emitec has also developed an electrically heated catalyst system designed to help engines with large displacements meet current and future emission standards. Called ...
