Method and device for determining the pressure in pipes

In a method for determining the absolute pressure in pipes through which there is a fluid flow, in particular injection lines in diesel-operated internal combustion engine, a first signal from a first pressure sensor is detected. This first signal is integrated. The integrated signal is multiplied b...

Zusammenfassung:	In a method for determining the absolute pressure in pipes through which there is a fluid flow, in particular injection lines in diesel-operated internal combustion engine, a first signal from a first pressure sensor is detected. This first signal is integrated. The integrated signal is multiplied by a factor. This multiplied factor is then added to an operating pressure. This method advantageously allows detection of the absolute pressure within the injection line that connects the rail of an internal combustion engine to the corresponding injector.
