Abstract
A method for determining a degree of aging of an oxidizing catalytic converter in an exhaust system of an internal combustion engine is provided. The method comprises generating a temporary increase in carbon monoxide levels in an exhaust gas stream, monitoring subsequent oxidizing action and determining a degree of aging of the oxidizing catalytic converter as a function of the measured oxidizing action. The method further comprises measuring a temperature rise during oxidation and correlating the aging of the converter to the speed of temperature rise.
