Combustion engine operation method involves determining maximum turning moment of engine for air-fuel ratio limit and resetting enable signal if required moment cannot be realized

摘要

The method involves selecting one of two operation modes. The maximum turning moment of the combustion engine at the air-fuel ratio limit is determined for the selected operation mode. An enable signal is reset when the required moment cannot be realized within the air-fuel ratio limit. The requested moment is the desired moment. An Independent claim is also included for the operation device for operating an internal combustion engine.
