Abstract
A low-temperature catalyst is provided for reducing cold-start hydrocarbon emissions. The catalyst comprises a platinum group metal impregnated onto an oxygen storage material. The catalyst may be used alone or may be included in a hydrocarbon trap containing a hydrocarbon adsorption material therein. The catalyst/hydrocarbon trap is positioned in the exhaust system of a vehicle downstream from a close-coupled catalyst such that the exhaust temperature at the catalyst location does not exceed 850° C. during normal vehicle operation and when combined with a hydrocarbon adsorption material in a trap, the exhaust temperature does not exceed 700° C.
