Abstract

Eine Brennkraftmaschine hat mehrere Zylinder, bei denen mindestens ein Zylinder als Referenzzylinder ausgebildet ist, dem ein Zylinderdrucksensor zugeordnet ist, wobei den Zylindern mindestens je ein Stellglied zugeordnet ist und ein Kurbelwellenwinkelsensor vorgesehen ist.An internal combustion engine has a plurality of cylinders, in which at least one cylinder is designed as a reference cylinder to which a cylinder pressure sensor is assigned, wherein the cylinders are each assigned at least one actuator and a crankshaft angle sensor is provided.

Ein Verbrennungskennwert, der für den Ablauf der Verbrennung des Luft-/Kraftstoff-Gemisches in dem Referenzzylinder charakteristisch ist, wird abhängig von dem Messsignal (MS) des Zylinderdrucksensors ermittelt. Mindestens eine Stellgröße für mindestens ein Stellglied wird bezüglich mehrerer Zylinder abhängig von dem Verbrennungskennwert im Sinne einer Anpassung des Ablaufs der Verbrennung in dem Referenzzylinder an einen vorgegebenen Ablauf der Verbrennung angepasst.

Figure imgaf001
A combustion characteristic characteristic of the combustion of the air-fuel mixture in the reference cylinder is determined depending on the measurement signal (MS) of the cylinder pressure sensor. At least one manipulated variable for at least one actuator is adjusted with respect to a plurality of cylinders as a function of the combustion characteristic value in the sense of adapting the course of the combustion in the reference cylinder to a predetermined combustion sequence.
