    摘要: The invention relates to a method for determining the composition of a fuel blend from a first and at least a second fuel to operate an internal combustion engine with at least one combustion chamber, wherein fuel blends of different composition combust at different optimal ignition angles ZWmax with an optimal degree of efficiency ηmax. Provision is thereby made for the ignition angle ZW of the internal combustion engine to be altered, for the degree of efficiency η of the internal combustion engine or a parameter, which is a function of it, to be determined as a function of the ignition angle ZW and for the composition of the fuel blend to be determined from the change in the degree of efficiency Δη or the parameter, which is a function of it, when the ignition angle ZW is altered and/or from the ignition angle ZW as a function of the degree of efficiency η or the parameter, which is a function of the degree of efficiency η. The method makes it possible to determine the fuel mixing ratio in the fuel tank of internal combustion engines, which can be operated with different fuels.

    摘要: A method and a device for operating an internal combustion engine including at least one cylinder are described, the at least one cylinder including at least one intake valve and at least one exhaust valve and a diagnosis of at least one erroneous intake valve or at least one erroneous exhaust valve is made possible without using a position acknowledgment. A gas exchange of the at least one cylinder is diagnosed thereby. For detection of at least one intake valve or exhaust valve for the existence of an erroneous valve position, at least one intake valve or exhaust valve of the at least one cylinder different from at least one intake valve or exhaust valve to be detected is brought into a predefined position, which is selected in such a way that the gas exchange of the at least one cylinder in the case of an erroneous valve position of the at least one intake valve or exhaust valve to be detected differs significantly from the gas exchange of the at least one cylinder for the case of an error-free valve position of the at least one intake valve or exhaust valve to be detected, a value characteristic for the gas exchange of the at least one cylinder being ascertained, this value being expected at the moment for an error-free state of the set valve positions of the at least one intake valve and the at least one exhaust valve of the at least one cylinder, the actual value characteristic for the gas exchange of the at least one cylinder being ascertained and an error in the position of the at least one intake valve or exhaust valve to be detected is recognized as a function of the deviation in the actual value from the expected value.

    摘要: A method and a device for operating a drive unit, in particular of a vehicle, are provided, which allow for an adaptation of losses of an output variable of the drive unit, in particular of a torque, which is precise and which restricts as little as possible a request to shut down the drive unit. For this purpose, the losses are adapted during at least one operating phase, in particular an idling operating phase, of the drive unit. With the conclusion of a successful adaptation, a shutdown of the drive unit is enabled.
