摘要： A fuel injector cup assembly has an injector cup, at least one bolt and an elastic element which mechanically couples the injector cup to a cylinder head. The bolt (7) is arrangeable through a penetrating first opening of the injector cup and in an opening of the cylinder head to fasten the injector cup to the cylinder head. The elastic element is configured to be mechanically coupled to the injector cup at a given position to act against a tilt of the injector cup relative to the cylinder head.

摘要： A holder for fastening at least one component, particularly a fuel distributor, to an internal combustion engine. The holder includes an elastically deformable damping element, a holder body and a spring element, which are situated lying one behind the other with reference to an axis. In response to an assembly using the fastening arrangement, a prestressing of the spring element and a prestressing of the damping element are made possible. Furthermore, a fuel injection system is described having a fuel distributor and such a holder, which is used for fastening the fuel distributor on an internal combustion engine.

摘要： A fuel injection system designed for an internal combustion engine includes at least one fuel injection nozzle which, by way of a cylindrical shell body, is inserted at least in regions into a bore of a cylinder head and which, by way of a nozzle tip, feeds fuel to a combustion chamber between the cylinder head and a reciprocating piston. The fuel injection nozzle is held in position on a housing section of the internal combustion engine with the interposition of a holding device and, for example, a fastening bolt. The holding device braces a first end region of the fuel injection nozzle against a bore stop within the bore in the cylinder head. To optimize this fuel injection system, the holding device has, outside the bore, a fixing bushing to which the shell body is fixed axially and radially by way of a radial insert element. A spring system acts between a first radial stop of the fuel injection nozzle and a second radial stop of the fixing bushing as viewed in the axial direction of the shell body of the fuel injection nozzle. The spring system seeks to move the fixing bushing, by way of a third radial stop, against a locking element system of the insert element, which is supported on a fourth radial stop applied to the shell body.

摘要： Provided is a protective structure (64) for a fuel pipe (45) extending along the intake side of an engine main body (9) under an intake manifold (20). A protective member (61) is placed in front of the fuel pipe. The protective member includes a pair of legs (64, 65) secured to the intake side of the engine main body, a main body (63) extending from the legs upward in an arcuate manner along a front side of the fuel pipe and bent rearward in an upper part thereof, and an abutting projection (63G) extending from an upper end of the main body and projecting upward and rearward. A fastening member (26, 27) is passed through a flange of the intake manifold, and includes an engagement feature (36) positioned behind a free end of the abutting projection. The protective member minimizes the loading transmitted to the fuel pipe at the time of a vehicle crash.

摘要： Methods and systems are provided for a fuel injector clamp for fixing a fuel injector to an engine component such as a cylinder head. Fuel injector clamps can be made from a variety of manufacturing processes, but some processes are more limiting in terms of material selection, structural properties of the clamp, and overall cost. A fuel injector clamp for use in a diesel engine is provided that has a design conforming to a stamping manufacturing process to increase the strength of the clamp as well as increase reliability while reducing the cost.
