Abstract
A method for operating an internal combustion engine of a motor vehicle with the engine developing a torque during the operation thereof includes deriving a desired value of the torque of the engine from operating variables. The desired value of the torque is made available by at least adjusting the air supply and the ignition angle of the engine. The efficiency of the engine is deteriorated in at least one operating state of the engine compared to the efficiency in operating states outside of the one operating state by retarding the ignition angle and increasing the air supply whereby the torque developed by the engine remains essentially constant. The presence of the one operating state is detected when a startup intent of the driver of the vehicle is recognized.
