Method for diagnosis of conversion of pollutants carried out by catalytic converter, involves separate determination of dynamic storage capacity for intake of oxygen and for discharge of oxygen from oxygen accumulator

摘要

The method involves separate determination of the dynamic storage capacity for intake of oxygen in oxygen accumulator and dynamic storage capacity for discharge of oxygen from oxygen accumulator. The conversion concerning the reduction of pollutant components is determined on the basis of dynamic storage capacity for intake of oxygen. The conversion performed concerning oxidation of the pollutants is determined on the basis of the dynamic storage capacity for discharge of oxygen.
