Abstract
The method involves determining a composition of a fuel mixture from a signal differently based on components of exhaust gas for pumping current (60) or a pumping current variation of a pumping cell of an exhaust gas probe (10) e.g. broadband lambda probe, of an internal combustion engine. The exhaust gas probe is installed in an exhaust gas channel of the engine. A defined mixture enriched fuel is provided periodically for known air mass. An independent claim is also included for a device for determining composition of a fuel mixture for operating an internal combustion engine.
