A connecting element for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component, in particular a fuel distributor rail. A base body having a receiving space is provided for this purpose. The base body has an opening, via which a fuel fitting of the fuel injector is insertable into the receiving space of the base body. Furthermore, a first annular element is provided in the receiving space, which in the installed state on the one hand interacts with the fuel fitting inserted into the receiving space and on the other hand interacts with the base body. Furthermore, a second annular element is provided in the receiving space of the base body, the first annular element and the second annular element abutting against an outside of the fuel fitting in the installed state.

A connecting element for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component. For this purpose, the connecting element has a base body, which is connected on the one side in a form-locking manner to the fuel-carrying component and on the other side is connected in a form-locking manner to the fuel injector. The base body is developed as a bracket-shaped base body, the base body having a first arm, a second arm and a connecting web. The base body abuts on a first contact surface, which is provided on the first arm, on the one side against the fuel-carrying component and on a second contact surface, which is provided on the second arm, on the other side against the fuel injector. An elastic decoupling is provided between the first contact surface and the second contact surface. Furthermore, a fuel injection system having a fuel-carrying component, a fuel injector and such a connecting element is indicated.

A connecting element for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component. A connecting part is provided, which is fastened on the one side on a shoulder of the fuel-carrying component and, on the other side, on a shoulder of the fuel injector. For this purpose, the connecting part is developed at least partially as a pot spring. A fuel injection system having such a connecting element is also indicated.
摘要:
A fuel injector, in particular for injecting fuel into an internal combustion engine, including a housing having at least one injection opening, an internal pole, which is stationary in relation to the housing, a magnet coil acting magnetically on the internal pole, an armature, which is linearly movable in relation to the housing, a valve needle, which is linearly movable in relation to the housing and in relation to the armature, forming a valve seat together with the housing, a first stop face, which is stationary in relation to the housing, and a second stop face, which is formed on the valve needle, the second stop face striking the first stop face in an end position of the valve needle at the maximum valve needle lift.
摘要:
A method for combusting fuel in a combustion chamber of an internal combustion engine, in which air is supplied to the combustion chamber via at least one intake valve and at least one fanned-out fuel spray is injected into the combustion chamber via at least one fuel injector in such a way that at least one layer charge cloud composed of a fuel/air mixture is produced and the layer charge cloud is ignited using at least one ignition device. For achieving a higher degree of efficiency during combustion, the at least one layer charge cloud is ignited in the combustion chamber at at least two spatially separated ignition points, the ignition being carried out simultaneously or staggered in time.

A connecting device for fuel injection systems is used for connecting a fuel injection valve to a fuel-carrying component. A wire-shaped connecting element is provided in this context, which is fastened, on the one hand, to the fuel-carrying component and, on the other hand, to the fuel injection valve. The wire-shaped connecting element is embodied closed in an annular manner, and, on the one hand, is guided about a shoulder of the fuel-carrying component and, on the other hand, about a shoulder of the fuel injection valve. A fuel injection system having such a connecting device is also provided.
