Abstract
An internal combustion engine () has a control arrangement () which regulates at least one control parameter for operating the engine (). The control arrangement () includes a non-volatile memory () and a main memory (). During operation of the engine (), an operating value (x) for the control parameter is continually stored in the non-volatile memory (). When starting the engine (), an initial value for the control parameter is determined. According to at least one criterion, a determination is made as to whether the operating value (x) stored in the non-volatile memory () or a standard value (x) is used as the initial value for the control parameter.
