摘要
The operating method has at least one sensor used for detecting the pressure in the high pressure region of the fuel metering system, supplied with fuel via at least one fuel pump and a pressure setting device, e.g. a valve, used for adjusting the pressure in the high pressure region, with the pressure variation rate being limited in dependence on the maximum feedrate of the fuel pump. Permissible pressure gradient values can be provided in dependence on the revs and engine loading using characteristic fields. Also included are Independent claims for the following: (a) a computer program for an automobile IC engine; (b) a control device for operation of a fuel metering system for an automobile engine; (c) a fuel metering system for an automobile IC engine
