Abstract: A method for influencing an aging process of a component of an exhaust aftertreatment system for a vehicle. An aging state of the component is predictively determined using an aging model. A characteristic value is determined from operating parameters from previous torque demands. An allowable torque is determined, taking into account the aging state of the component and the characteristic value at which a limit value of a compliant aging condition of the component is undershot. A current torque demand is compared with the allowable torque. A signal is issued if the current torque demand exceeds the allowable torque. A control command of a motor control unit is triggered. The control command being selected in the case of a deviation of the exceedance of the current torque demand from the allowable torque.

Abstract: The present disclosure relates to a combustion process for an internal combustion engine, in which a fuel mixture composed of a dimethyl ether-containing first fuel and a methane-containing second fuel is combusted, wherein the premixed fuel mixture or the fuels independently are fed directly to at least one combustion chamber of the internal combustion engine and/or indirectly via at least one intake pipe of the internal combustion engine upstream of the at least one combustion chamber, wherein the fuel mixture present in the respective combustion chamber is combusted by self-ignition with addition of combustion air on the intake pipe side.

Abstract: A method and a system for determining a fuel consumption of a vehicle. The method comprises determining a fuel consumption based on a consumption-dependent variable and based on at least one standard value of a fuel material property. The method further comprises determining a fuel material property of the fuel used by the vehicle, calculating a correction value based on the determined fuel material property, and determining a corrected fuel consumption based on the determined fuel consumption and the correction value. In particular, the net CO2 emission or the greenhouse gas emission can be determined from the renewable share.
