Force material pressure sensor power - diagnostic systems and - the method on the basis of the hydrodynamics of the injection

摘要

A press control system comprises a model pressure - determination module and a sensor diagnosis module. The determined model pressure - determination module on the basis of an injection duration of a fuel injection system and a desired fuel mass which is injected by the fuel injection system, a modeled force material distributor pipe pressure. The sensor diagnosis module generates on the basis of a comparison of the modeled force material distributor pipe pressure and a sensed force material distributor pipe pressure a status of a fuel distributor tube - pressure sensor.
