  • Combatting air pollution
    Patent number: 5939028
    Abstract: The hydrocarbon light-off time in engine exhaust is reduced by employing a hydrogen oxidation catalyst, a CO oxidation catalyst of light-off temperature for CO and/or hydrogen below ambient temperature, and sufficient oxygen and sufficient CO and/or hydrogen in the exhaust that the exothermic reaction of the oxygen with the CO and/or hydrogen over the CO oxidation catalyst generates enough heat to raise the temperature of the CO oxidation catalyst to at least the light-off temperature of the hydrocarbon oxidation catalyst.
