Abstract: In an internal combustion engine with auto-ignition in which the fuel is injected directly into the combustion chamber by means of a fuel injection nozzle in the form of multiple fuel jets, wetting of the combustion chamber-side cylinder head surface is minimized by recesses formed in the cylinder head whereby some of the fuel is reflected by the piston towards the cylinder head when the piston is in a position adjacent the cylinder head and directed at least partially into the recesses formed in the cylinder head.
