    Abstract: The present disclosure describes a method for checking the signal of a temperature sensor in an exhaust-gas aftertreatment system for an internal combustion engine. The method may include: in an operating state which does not require heating of the reducing agent, activating the heating device for the purposes of checking the temperature sensor; determining whether the signal of the temperature sensor changes by a predefined expected value (ΔT) within a predefined time period (Δt2); provisionally identifying the temperature sensor as fault-free if it does; deactivating the heating device; determining whether the signal of the temperature sensor reaches the start temperature (T0) again within a time period (Δt3); and confirming the temperature sensor as fault-free if it does.

    Abstract: A method for determining the composition of a fuel in a lubricant in an internal combustion engine in disclosed. The composition of a fuel having at least a first portion of a first fuel component and a second portion of a second fuel component is predefined. The mass flow with which the fuel is introduced into the lubricant in an introduction phase or discharged from the lubricant and from the housing in a discharge phase is determined. The composition of the mass flow is determined from a first mass flow of the first fuel component and a second mass flow of the second fuel component, which are determined based on a) an introduction parameter in the introduction phase or a discharge parameter in the discharge phase, and b) the first portion of the first fuel component and the second portion of the second fuel component in the fuel.

    Abstract: The present disclosure relates to engines for a motor vehicle and some embodiments include a method for operating an exhaust train of a motor vehicle engine including: measuring a particle concentration downstream of a particle filter at a first operating point; determining the filter efficiency at the first operating point; changing operation of the engine to a second operating point to increase the particle emissions; measuring the particle concentration downstream of the filter at the second operating point; determining the filter efficiency at the second operating point; determining a difference between the efficiency levels; detecting an offset error, if the difference exceeds a defined threshold; and identifying a particle sensor as defective if an offset error is detected, rather than identifying the particle filter as defective.

    Abstract: A method for checking the leak-tightness of hydraulic components in an exhaust gas aftertreament unit of an internal combustion engine is disclosed. The exhaust gas aftertreament unit uses an electric motor to pump a liquid reductant from a reductant reservoir to a reductant injector that is kept closed. The reductant pump is switched on for a first predetermined period, and the electric current consumed by the electric motor is detected during this period. After a predetermined standstill time has passed, the reductant pump is switched on again for a second period identical to the first period, and the electric current consumed by the electric motor is again detected during this period. The electric currents detected during the two time periods are compared with each other, and the leak-tightness of the hydraulic components downstream of the reductant pump is evaluated based on the result of the comparison.
