Abstract

Die Erfindung betrifft ein Verfahren zur Reduzierung von Ablagerungen innerhalb von Spritzlöchern. Hierzu wird ein Injektor in der sogenannten Sitzdrosselung betrieben. Dadurch wird es ermöglicht, dass verschiedene Reinigungssequenzen zu definierten Zeitpunkten bei Sitzdrosselbetrieb und/oder zu bestimmten Betriebspunkten durchgeführt werden können.
