Abstract
A system for increasing temperature in an exhaust aftertreatment system upstream of an exhaust aftertreatment device, such as a selective catalyst reduction (SCR) device, is provided. In one form, the system includes a component within an exhaust stream being exposed to exhaust flow and temperatures of at least 200° C. At least one surface of the component includes an adhered ceramic coating that functions as a catalyst to accelerate heating of the exhaust flow. In another form, a secondary catalyst is adhered to the ceramic coating. The component may be a part or parts of a turbocharger, such as nozzles, vanes, runners, and blades.
