ABSTRACT:
In an internal combustion engine with direct fuel injection having a cylinder, a piston and a cylinderhead defining together a combustion chamber, a fuel injector with a fuel injection nozzle is mounted in the cylinder head for delivering fuel from the fuel injection nozzle into the combustion chamber so as to form a mixture cone. A spark plug is mounted in a spark plug sleeve disposed in the cylinder head and projects into the combustion chamber beyond the spark plug electrodes and into the mixture cone so as to form at its front end adjacent the spark plug electrodes an open ignition chamber in which part of the rich fuel mixture of the fuel mixture cone is collected for ignition by the spark plug.
