Abstract

A method is provided for monitoring the regulation of smooth running of a multi-cylinder internal combustion engine. The smooth running is regulated using at least one manipulated variable, which can be controlled by a control device, to influence the smooth running behaviour, and in which the measurement signals which correspond to temperatures on the catalytic converter are obtained.
