Abstract:
1. A fuel injection system for direct injection of fuel into a combustion chamber of an internal combustion engine, comprising: at least one fuel injection valve, a cylinder head having at least one receiving bore defining a first section and a second section demarcated by an annular step, said at least one fuel injection valve disposed in said first and second sections of at least said one receiving bore, in order to inject fuel into the combustion chamber; a fuel distributor line, for delivering the fuel to the fuel injection valve; a compensation element for positional compensation and/or tolerance compensation, which is disposed in the radial direction between the fuel injection valve and the cylinder head in contact relation with said fuel injection valve and said first section of said receiving bore, and which is disposed in an axial direction of the fuel injection valve between a first sealing element, which seals at a side of the fuel injection valve oriented toward the combustion chamber between the fuel injection valve and the cylinder head, and a second sealing element, which seals between the fuel injection valve and the fuel distributor line; and a bracing ring, which is disposed between the fuel injection valve and the cylinder head about said step and furnishes bracing of the fuel injection valve in the axial direction at said step of the receiving bore, said bracing ring having a smaller diameter than said first section of said bore to provide play therebetween in the radial direction.
