Catalytic Purification of Automotive Exhaust Gases Under European Conditions 800394

Recently developed catalytic systems on a precious metal/metal support basis were tested unter European conditions using low leaded gasoline (0.15 g/l). Catalyst aging was carried out on European middle class cars with an automatic roller-dynamometer over 50000 km. The AMA durability test cycle was applied. The deterioration factor of the catalytic unit was small enough under these conditions to fulfill emission standards proposed by the German “Umweltbundesamt” (UBA). Road tests with similar catalytic systems confirmed the results obtained with the AMA durability test.
