摘要：
A method of lowering undesirable vehicle exhaust emissions includes preparing a catalyst for use in the exhaust stream of the vehicle. The method includes impregnating one group of alumina substrates with platinum, impregnating another group of alumina substrates with palladium, and the mixing the first and second groups of impregnated substrates.
