ABSTRACT:
An internal-combustion engine has predominantly swirl-free air inflow into a shallow combustion space. A centrally arranged injection nozzle with preferably eight spray holes projects into the combustion space. The nozzle has a piston with a piston recess. Depressions are formed in the recess bottom of the piston recess and correspond to the number of injection jets. The depressions extend from the center of the piston in the direction of the injection jets, are matched to the jet shape and have a corrugated shape in the circumferential direction of the piston recess.
