Abstract (en)
[origin: WO2007031492A1] A device and a method for monitoring a fuel metering system are described, in which system fuel is fed from a low-pressure region into a high-pressure region. The pressure in the high-pressure region is sensed. A fault is detected on the basis of the pressure profile in the high-pressure region. The type of fault is detected on the basis of the shape of a pressure reduction curve. The profile of the pressure variable over time is approximated with a function such as a hyperbolic function. The type of fault is identified on the basis of the variable which characterizes the function.
