Technician A says that during oxidation, as NO x gases pass over the catalyst, the N atoms are pulled from the NO x molecules and are absorbed by the catalyst. The released oxygen atoms then flow through the converter to the second bed. The result of NO x oxidation is pure nitrogen plus oxygen or carbon dioxide. Technician B says that during the reduction phase inside the converter, hydrocarbon and carbon monoxide molecules experience a second combustion. The result of this combustion or oxidation process is water vapor and carbon dioxide. Who is correct? a. Technician A only b. Technician B only c. Both A and B d. Neither A nor B
