In an internal combustion engine with at least one cylinder in which a combustion space is delimited between a piston and a cylinder head, with a fuel injector having an outwardly opening injection nozzle arranged in the combustion space for injecting fuel in the form of a hollow cone into the combustion space, and a spark plug mounted in the cylinder head and having electrodes arranged outside the hollow fuel cone generated by the injection nozzle, into which the electrodes of the spark plug project, the cylinder has a bore diameter (D) dimensioned such that, at an ignition time point of the internal combustion engine, a ratio dmR/D of the mean diameter (dmR) of the fuel boundary vortex ( 10 ) to the cylinder bore diameter (D) is in a range of 0.08 to 0.2, in particular of 0.1 to 0.12.
