Abstract
A device for a fuel system that makes a fuel available for an operation of an internal-combustion engine where the fuel system includes a fuel pump which conveys the fuel into a fuel accumulator and includes one or more injection nozzles which convey the fuel from the fuel accumulator to a working mixture of one or more cylinders of the internal-combustion engine includes an evaluation unit. The evaluation unit is configured to ascertain pressure data with respect to a physical pressure in the fuel accumulator during an operation of the fuel system at a sampling-time, ascertain a change in a reference pressure at the sampling-time with aid of a reference model of the fuel system, and detect a defect of the fuel system on a basis of the pressure data and on a basis of the change in the reference pressure.
