Abstract
Die Erfindung betrifft ein Verfahren zum Betreiben einer über wenigstens einen Zylinder verfügenden Brennkraftmaschine, insbesondere ein Gasmotor, vorzugsweise ein Magergasmotor. Zur Verbesserung des Verbrennungsprozesses wird vorgeschlagen, dass zur Zündung eines Gemisches in einer Hauptkammer (4) eine Vorkammer (5) vorgesehen ist, wobei ein Druckverlauf von einem Drucksensor in der Hauptkammer (4) in Abhängigkeit eines Kurbelwinkels ermittelt wird und wobei in Abhängigkeit einer gewünschten Leistung und/oder eines gewünschten Drehmoments und/oder einer gewünschten Drehzahl der Brennkraftmaschine die zugeführte Menge an Brennstoff zylinderindividuell mithilfe einer Brennstoffdosiereinrichtung (30, 10) und des Drucksensors gesteuert oder geregelt wird.
