Abstract
A method for monitoring the capability of a catalytic converter to convert nitrogen monoxide into nitrogen dioxide in the exhaust gas of an internal combustion engine, the catalytic converter being arranged in an exhaust gas duct of the internal combustion engine and the catalytic converter being followed downstream by a collecting particle sensor. It is in this case provided that, in a monitoring cycle, a decrease in the particle loading of the particle sensor during the operation of the internal combustion engine under predetermined operating conditions is taken to conclude an adequate capability of the catalytic converter to convert from nitrogen monoxide to nitrogen dioxide.
