The Influence Of Vehicle Parameters On Catalyst Space Velocity And Size Requirements

An empirical relationship has been developed which permits the sizing of catalytic converters for control of vehicle exhaust emissions when the converter operates under mass transfer limited conditions. The relationship is based upon the inertia weight only, and may be utilized-within certain limitations- to determine the size of catalyst required for a given vehicle when another vehicle, which is equipped with a catalyst of proven durability, is used as a reference.
