Abstract in another language

For operating a three-way catalyst (TWC) in the maximum conversion region, the normalized air-tofuel ratio λ of the exhaust gas of gasoline operated vehicles is measured by a lambda-probe upstream of the TWC. The electrical conductivity of TWC-washcoats used today varies with the oxygen partial pressure of the atmosphere and can therefore be employed alternatively for λ-measurement.
