摘要： The invention concerns a method to determine the composition of a fuel from the components ethanol and gasoline of an internal combustion engine, wherein the fuel is supplied to the internal combustion engine by a fuel supply unit and via two fuel distributor rails; and the exhaust gas is discharged from the internal combustion engine by two exhaust gas manifolds of a first and a second exhaust gas system, which are separated from each other, wherein the first and second exhaust gas system have in each case at least one exhaust gas probe and wherein current changes in the ethanol content of the fuel are evaluated from the signal differences of lambda signals from the exhaust gas probes. With this method, a change in the ethanol content of the fuel can be detected, and an explicit condition for a change in fuel can be derived. Moreover, with the method, errors in the fuel-mixture can be distinguished from an altered fuel composition, which takes place after the tank has been filled fueling.

摘要： A method and a device are provided for operating an internal combustion engine which allow for an improved diagnosis of the valve mechanism of cylinders of the internal combustion engine. For this purpose, a variable characteristic of a suction performance of a cylinder of the internal combustion engine is ascertained.

摘要： A method and a device for operating an internal combustion engine make it possible to shift the combustion limit. In this context, a predefined output variable of the internal combustion engine such as the torque, for example, is realized in at least one operating state of the internal combustion engine by at least a retardation of an ignition angle. It is checked whether, due to the retardation of the ignition angle, a variable like, for example, a misfiring, characteristic for the combustibility of the air/fuel mixture in a combustion chamber of the internal combustion engine, exceeds a predefined limiting value in terms of a deterioration of the combustibility, and in this case, at least one actuator of the internal combustion engine, different from an actuator for setting the ignition angle, such as the exhaust-gas recirculation valve or EGR valve, for instance, is controlled along the lines of improving the combustibility of the air/fuel mixture.
