Verfahren und Vorrichtung zur Optimierung der Verbrennung von Dieselkraftstoffen mit unterschiedlichen Cetanzahlen in einer Diesel-Brennkraftmaschine

摘要

The invention relates to a method and a device for optimizing combustion of diesel fuels with different cetane numbers in a diesel internal combustion engine. It is provided that cylinder pressures are measured in at least one cylinder of the internal combustion engine during the combustion period, that at least one part of the measured cylinder pressures is evaluated in order to derive a characteristic value for the diesel fuel that is fed into the cylinder of the internal combustion engine, and that the characteristic value is used to change parameters that determine the combustion in the cylinders of the internal combustion engine.
