Abstract (en)
[origin: WO0183971A1] The invention relates to a device and a method for monitoring a fuel metering system of an internal combustion engine, especially a common rail system. The fuel is compressed by a pump and a pressure value characterising the fuel pressure is detected. A defect is identified when a filtered pressure value deviates from a threshold value.
