Method for operating internal combustion engine of motor car, involves determining heating power of the internal combustion engine and on-board network of the motor car

摘要

The method involves arranging the internal combustion engine (1) with an exhaust gas purifying device (2). The exhaust gas is flowed through the exhaust gas purifying device from the oxidation catalyst (12) over the catalytic converter (13) to the soot particulate filter (14). The catalytic converter is heated by an electric heater (16). The heating power of the internal combustion engine and on-board network of the motor car is determined. An independent claim is included for internal combustion engine.
