A fuel distributor, which is used in particular for fuel injection systems of mixture-compressing spark ignition internal combustion engines, includes a tubular base body, a first holder and a second holder. The first holder is connected here to the tubular base body at a first fastening point of the tubular base body. The second holder is also connected to the tubular base body at a second fastening point of the tubular base body. The tubular base body has at least one bend at least between the first fastening point and the second fastening point. A base body having a meandering pattern may be implemented in this way, enabling adjustment of thermal changes in the length of a cylinder head on which the fuel distributor is mounted.

A fuel distributor, which is used, in particular, for fuel injection systems of mixture-compressing, internal combustion engines having externally supplied ignition, includes a distributor pipe, a first holder and at least one second holder. The distributor pipe has a longitudinal axis. In this connection, the first holder and the second holder are situated at the distributor pipe so as to be axially set apart from one another with respect to the longitudinal axis. The distributor pipe is designed to allow axial length compensation. It is also possible for at least one holder to be designed to allow axial length compensation.

A component of a fuel injection system, designed in particular as a fuel distributor or a fuel injector, includes a base body on which at least one electric line is provided. The electric line is applied to the base body by plasma coating. In addition, a fuel injection system, used in particular for motor vehicles, includes a fuel distributor and multiple fuel injectors mounted on the fuel distributor.

A fuel distributor which is used particularly for fuel injection systems of mixture-compressing, spark ignition internal combustion engines, includes a first half shell and a second half shell. A fuel chamber is embodied between the half shells. A plurality of cups is embodied on the first half shell and/or on the second half shell. The first half shell and the second half shell are connected to each other in a continuous material manner. Such a fuel distributor is especially suitable for medium pressure, particularly between 5 MPa and 7 MPa.

A fuel injection valve for fuel injection systems of internal combustion engines. The valve includes an electromagnetic actuating element having a solenoid, a solid core, an outer magnetic circuit component, and a movable armature for actuating a valve closing element that works together with a valve seat surface provided on a valve seat element. The valve has extremely small outer dimensions. Due to an optimized dimensioning of the electromagnetic circuit, the outer diameter of the outer magnetic circuit component in the circumferential area of the solenoid DM

A fuel injector for fuel injection systems of internal combustion engines. The valve includes an electromagnetic actuating element which has a solenoid, a solid core, an external magnetic circuit component, and a movable armature for activating a valve closing member which cooperates with a valve seat surface provided on a valve seat member. The valve has extremely small outer dimensions. By optimizing the dimensions of the electromagnetic circuit, the outer diameter of the external magnetic circuit component in the peripheral area of the solenoid is 10.5 mm
摘要:
A fuel injector for fuel-injection systems of internal combustion engines includes an electromagnetic actuating element having a solenoid coil, a fixed core, an outer magnetic circuit component, and a movable armature for actuating a valve-closure element, which cooperates with a valve-seat surface provided on a valve-seat element. The injector is characterized by its extremely small outer dimensions. The flexibility in the installation of fuel injectors of varying valve lengths, which is made possible very simply due to the special modular design, is significantly increased in this manner. An optimized dimensioning of the electromagnetic circuit allows for a DFR (dynamic flow range) greater than 17, the DFR being defined as the quotient of qmax/qmin.
摘要:
An injector having a valve opening, a cylindrical pipe, a valve opening, a valve needle situated inside the pipe in the radial direction and guided to allow axial displacement; a solenoid coil situated outside the pipe in the radial direction; a solenoid core disposed inside the pipe in the radial direction; and a magnetic armature situated inside the pipe, opposite the solenoid core in the radial direction, the magnetic armature being disposed on the valve needle. The pipe is a magnetic first material in a first pipe region and a third pipe region, the first region facing the valve opening in the axial direction, and the third pipe region facing away from the valve opening in the axial direction. The pipe is a non-magnetic second material in a second pipe region, the second pipe region being between the first pipe region and the third pipe region in the axial direction.
