该燃料喷射系统（2），用于设计的内燃机（1），包括至少一个燃料喷射器（3）具有圆柱形壳体（9）至少在气缸盖的一个孔（10）部分（7）插入，和（与喷嘴尖端 11）向汽缸盖（7）和往复式活塞之间的燃烧室供应燃料，其中燃料喷嘴（3）借助于保持装置（4）和例如 在位置的内燃机（1），该保持装置（4）包括燃料喷射喷嘴（3）相对于在所述气缸盖中的孔（10）内的孔止动件（17）的第一端部（5）上的壳体部分保持的紧固螺钉（15）（7 ）时态。 为了优化该燃料喷射系统（2），所述孔（10）的固定套筒（18）的外部保持装置（4），在其上壳体（9）通过径向滑动构件的装置（20）沿轴向和径向固定在轴向 所述鞘主体的方向（9）的燃料喷射器（3）被认为是燃料喷射器（3）的第一径向止挡（21）和所述固定衬套的第二径向止挡（22）（18）之间的东西具有弹簧系统（23）是有效的，所述固定衬套 （18）倾向于通过第三径向止挡（24）的装置移动到阳部件（20）的锁定构件系统，配套连接是在第四到壳体主体（9）的径向止动件（26）。

This fuel injection system (2) for an internal combustion engine (1) designed, comprising at least one fuel injector (3) with a cylindrical shell body (9) at least partially in a bore (10) of a cylinder head (7) is inserted, and (with a nozzle tip 11) a combustion chamber between the cylinder head (7) and a reciprocating piston supplies fuel, wherein the fuel injector (3) through the intermediary of a holding device (4) and, for example, a fastening screw (15) on a housing portion (5) of the internal combustion engine (1) is held in position is, which holding device (4) spans a first end portion of the fuel injection nozzle (3) against a bore stop (17) within the bore (10) in the cylinder head (7). In order to optimize this fuel injection system (2), the holding device (4) outside the bore (10) a fixing sleeve (18), on which the shell body (9) by means of a radial slide member (20) is fixed axially and radially, in the axial direction of the sheath body (9) of the fuel injector (3) is considered as something between a first radial stop (21) of the fuel injector (3) and a second radial stop (22) of the fixing bushing (18) has a spring system (23) is effective, the fixing bushing (18) tends to move to a locking member system of the male member (20) by means of a third radial stop (24), supporting the attached is at a fourth to the casing body (9) radial stop (26).
