Abstract
The invention relates to a method for controlling an internal combustion engine with a motor control system that adjusts the exhaust-gas temperature by influencing the air-fuel mixture. Said motor control system has a temperature model so as to determine a preset temperature for a component in the exhaust manifold, which is achieved after a longer period of time while maintaining current operating and driving conditions. The motor control system regulates the exhaust-gas temperature depending on the preset temperature for the purpose of component protection.
