    摘要: In a method for adjusting the fuel/air ratio in an internal combustion engine (1) comprising a converter (2) which is associated therewith, a composition of waste gas in the waste gas wing (3, 8) of the internal combustion engine (1) is detected by means of sensors (4, 5) and output signals from at least one of the sensors (4, 5) are used for producing a control signal in order to influence the fuel/air ratio. The fuel/air ratio is switched back and forth between a lean operating state with surplus oxygen and a rich operating state with an oxygen deficit by means of a characteristic line of the control signal. The characteristic line of the control signal is adapted to a current converter state. A characteristic curve contour of the characteristic line is adjusted according to the addition and/or desorption of an oxidation agent in the converter (2). The invention also relates to a device for carrying out said method.

    摘要: A method relates to operating an internal combustion engine in the form of an Otto engine, especially of a motor vehicle. Otto engine fuel (i.e., carburetor fuel, spark ignition engine fuel), such as gasoline or ethanol (E85), are directly injected into at least one combustion chamber of the internal combustion engine with at least one fuel injector. Optionally, instead of injecting ignition spark engine fuel or in addition, the internal combustion engine is operated with gas, especially CNG (compressed natural gas) or LPG (liquefied petroleum gas). During operation of the internal combustion engine with gas only, the engine is automatically switched to the operation with spark ignition engine fuel for a predetermined period, or the engine is switched to the operation with spark ignition engine fuel in addition to the operation with gas, in such a manner that a predetermined quantity of the carburetor fuel flows through the at least one fuel injector. The engine is then automatically switched back to the operation with gas only.
