Fuel injection system

A fuel injection system for directly injecting fuel into at least one combustion chamber of an internal combustion engine, the internal combustion engine including a cylinder head, the fuel injection system comprising:

• at least one fuel injection valve cooperating with the at least one combustion chamber and including:
• a spray section for inserting into a receptacle bore hole in the cylinder head, and
• an inlet section having a fuel inlet opening;
• a fuel distributor line having a fuel outlet opening for the at least one fuel injection valve, the fuel distributor line being contestable to the fuel inlet opening of the at least one fuel injection valve;
• and
• a receptacle element situated on the fuel outlet opening of the fuel distributor line, the receptacle element snarlingly accommodating the fuel inlet opening of the at least one fuel injection valve to form a first sealing arrangement, the first sealing arrangement securing the at least one fuel injection valve in the receptacle element at the inlet section and enabling the at least one fuel injection valve to pivot in a first predetermined angle range,
• wherein the cylinder head has a partial spherical-shaped supporting face, the partial spherical-shaped supporting face being provided at the receptacle bore hole and on a side of the cylinder head which faces the fuel distributor line, and
• wherein the at least one fuel injection valve further includes a supporting section, the supporting section being supported on the partial spherical-shaped supporting face to form an arrangement enabling the at least one fuel injection valve to pivot in a second predetermined angle range, and a second sealing arrangement securing the at least one fuel injection valve in the receptacle bore hole at the spray section.
