In an internal combustion engine having at least one cylinder, in which a combustion chamber is delimited between a piston and a cylinder head, a fuel injector, is arranged in the cylinder head and has an injection nozzle with a plurality of injection bores. A piston depression is arranged in the piston, and a compression projection, with a projection cone angle, is positioned opposite the injection nozzle in the piston depression. The injection bores are formed such that, during a fuel injection in a range from 20° CA before top dead center to 35° CA after top dead center, the fuel jets emerging from the injection bores with a fuel cone angle impinge on the piston depression and are guided by a piston depression surface. The injection bores and the compression projection are formed such that a generated ratio of fuel cone angle to projection cone angle is in a range between 0.95 and 1.36, so that the injected fuel mass is distributed uniformly within the piston depressions, and a mixture of fuel with combustion air is intensified.
