Zusammenfassung:In an internal combustion engine having at least one cylinder in which a combustion chamber is delimited between a piston and a cylinder head which includes at least one intake duct, at least one exhaust duct, a fuel injector arranged in the cylinder head and having outwardly opening injection nozzle through which fuel is injected into the combustion chamber in the form of a hollow cone, and a spark plug arranged in the combustion chamber ( 4 ) in such that the electrodes of the spark plug ( 7 ) are situated outside the injected hollow fuel cone formed during fuel injection, the fuel injector is positioned in the cylinder head in such a way that a first spacing (E) is provided between a fuel outlet opening and an intake passage axis, and the cylinder bore having a diameter (D), wherein a first ratio (E/D) is provided in a range from 0.15 to 0.22.
