Use of High Cell Density Monolithic Catalysts for Automotive Exhaust Emission Control 820483

SUZUKI MOTOR CO., LTD., as the first Japanese automobile manufacturer to use monolithic catalysts to meet Japanese automotive exhaust emission standards. Monolithic catalysts were used in mini-car production (450 cc, 2-stroke engine) to meet the 1975 2-stroke engine emission standards.

High cell density monolithic catalysts of 600 cells/in ² have been investigated recently. High cell density allows for reduced precious metal loading without reducing catalyst activity or durability when compared to lower cell density catalysts of the same volume.

These high cell density monolithic catalysts have an added advantage of lowering NOx exhaust emissions.

This paper describes recently developed high cell density monolithic catalysts that have been used on production vehicles since August 1981
