Method and device for diagnosing the failure of a fuel delivery device in a fuel system |
摘要 |
A method and a device are described for diagnosing a fuel system having a plurality of electric fuel delivery units, which are submerged on the inlet side in a fuel supply contained in a fuel tank, and which, on the outlet side, deliver fuel in a fuel line to an internal combustion engine. The currents of the electric fuel delivery units are measured directly or indirectly in an analysis unit, compared to one another, and a diagnostic signal in digitized form is generated as a function of the result of the comparison.
