Abstract

See full text

An operating mode for an internal combustion engine, in particular a directly injected internal combustion engine having a plurality of combustion chambers, in particular for a directly injected gasoline engine, e.g. for a motor vehicle, having low NOx combustion (NAV). During the NAV operating mode that is the subject matter of this invention, at an ignition point (ZZP) a largely homogeneous, lean fuel/exhaust gas/air mixture having a combustion air ratio of λ≧1 in the respective combustion chamber is spark ignited by an ignition device, whereby the flame front combustion initiated by the ignition device (FFV) transitions to a controlled auto-ignition (RZV). The NAV operating mode enables a controlled auto-ignition to be performed in an engine load range in which a pure RZV operating mode is no longer stable enough to be implemented.
