METHOD FOR PLAUSIBILIZING A RAIL PRESSURE SENSOR VALUE

摘要

A method for plausibilizing a rail pressure sensor value of a rail pressure sensor of an internal combustion engine having a common rail system that has a fuel high-pressure piston delivery pump includes acquisition of the beginning of conveying by the piston delivery pump, calculation of the rail pressure from the compression work performed by the piston, and plausibilization of the rail pressure outputted by the rail pressure sensor on the basis of the calculated rail pressure.
