Claim 0:
1. Cylinder head of an internal combustion engine comprising:
at least one spark plug having at least one earth electrode configured and arranged to form an ignition spark, and
a precombustion chamber component configured and arranged to accommodate the spark plug and forms a precombustion chamber, and
a fuel channel which leads into the precombustion chamber and is arranged in the precombustion chamber component, wherein a flow axis (S) of the fuel channel at an outlet is oriented in the direction of the earth electrode, so that substantially the entire fuel flow (B) flows to the earth electrode, and wherein the fuel channel is curved in at least one direction,
wherein an axis of rotation (D) of the spark plug has an offset (x) with respect to an axis (A) of the precombustion chamber, and the offset (x) is between 0 and 15% of the greatest precombustion chamber diameter (g);
wherein the flow axis (S) in the region of the outlet is arranged substantially normal to an axis (A) of the precombustion chamber, so that the incident flow of the ignition spark is substantially normal to the axis (A) of the precombustion chamber, and
a fuel valve is arranged in the precombustion chamber component inclined with respect to a straight line parallel to the axis (A) of the precombustion chamber, wherein an inclination of the fuel valve is greater than or less than 0°.
