Abstract
An internal combustion engine has compression ignition, in which fuel is injected as a pre-injection and main injection directly into a working space by means of an injection nozzle having a plurality of injection holes, with the pre-jection taking place in a clocked manner. In order to minimize the moistening of the walls of the combustion chamber, a combustion chamber is provided, in which are arranged an injection nozzle in the region of a cylinder center axis in the cylinder head and a piston recess arranged in the piston head, with an approximately centrally situated piston recess projection being arranged in the piston recess. The stroke of a nozzle needle of the injection nozzle is set in such a manner that a restricting of the range of the injected fuel jets is obtained.
