Method for determining composition of fuel mixture of fuels for operating internal-combustion engine, involves determining composition of fuel mixture of fuels from change of characteristic line of exhaust probe

摘要

The method involves determining the composition of a fuel mixture of the fuels from a change of a characteristic line of an exhaust probe (26). A catalyst converter (14) is arranged in an exhaust channel (13) of an internal-combustion engine (10). A lambda control system (25) and another lambda control system (27) evaluate an output signal of the exhaust probe and another exhaust probe (28). An independent claim is included for a device for determining a composition of a fuel mixture from the fuels for operating an internal-combustion engine.
