Abstract
The diagnosis of the heating of a catalytic converter situated in an exhaust system of an internal combustion engine is described. The system includes monitoring the actual ignition angle intervention. A current ignition angle is acquired over a specified time and converted into a torque model used for catalytic converter heating. Using the torque model, a degree of fulfillment of executed catalytic converter heating measures is obtained and an error signal is generated by comparing the obtained degree of fulfillment to a limiting value.
