Three-Way Catalytic Converter
-
The three-way catalytic (TWC) convener contains either platinum (Pt) and rhodium (Rh) or palladium (Pd) and rhodium (Rh). The TWC converter
catalyzes the oxidation reactions of unburned HCs and CO and the reduction reaction of NOx. The three-way conversion only occurs with the air
fuel/ratio near stoichiometry.
