An internal combustion engine has a preparation device for fuel, for the purpose of providing a starting fuel which comprises low-boiling fuel constituents. A catalytic converter is accommodated in an exhaust train of the internal combustion engine. After-treatment of the exhaust gases is carried out by a secondary air device, by means of the combustion being carried out with an excess of starting fuel for rich-burn operation during the cold start and the subsequent warm-up phase. The system is provided for spark-ignition mixture-compressing or spark-ignition direct injection internal combustion engines.
