Abstract
In an internal combustion engine with at least one injection device per cylinder for direct fuel injection into a combustion chamber, the injector nozzle is located in a top surface of the combustion chamber, which is formed in the cylinder head. In order to reduce the build-up of deposits and carbon residues in the region where the injection device enters the combustion chamber, the area around the injector nozzle is configured as a flow-directing surface for a swirl and/or tumble flow.
