Summary:THE PRESENT INVENTION DISCLOSES NOVEL CATALYSTS FOR TREATING AUTOMOBILE EXHAUST THAT HAVE INCREASED RESISTANCE TO POISONING FROM OIL-AND/OR FUEL-DERIVED ADDITIVES. IN THE CATALYSTS OF THIS INVENTION, THE CATALYTIC MATERIALS ARE NOT COATED ONTO A FRONT-END POISON CAPTURE ZONE (20, 38) OF THE SUPPORT THAT CARRIES THE CATALYTIC LAYERS. SINCE POISONOUS ELEMENTS TEND TO DEPOSIT ON THE UPSTREAM END OF THE CATALYST (30), SUCH POISONS DO NOT INACTIVATE ANY OF THE CATALYTIC MATERIALS. (FIGURE 1)
