Various embodiments include a sensor for use in an exhaust gas stream of an internal combustion engine comprising: a first electrode; a second electrode electrically insulated from the first electrode by an insulation; and a connection arrangement secured to the first electrode and the insulation by a solder connection. The connection arrangement is configured to position the first electrode relative to the second electrode. The solder connection is arranged at least partly outside an electric field generated during measurement operation of the sensor by applying a first electrical potential to the first electrode and applying a second, different, electrical potential to the second electrode.

Sensor for use in an exhaust gas stream of an internal combustion engine

Various embodiments include a method for the production of a sensor for an exhaust gas stream of an internal combustion engine, wherein the sensor comprises a first electrode and a second electrode. The method comprises: arranging a glass solder in a mold substantially between and substantially insulating the first electrode and the second electrode; arranging an insulating element in the mold in contact with a free surface of the glass solder; and finish molding the glass solder into a glass insulator together with the insulating element in a predetermined position relative to the first electrode and the second electrode. The insulating element shapes the glass insulator during the finish molding and at least partially isolates the glass insulator from the exhaust gas of the internal combustion engine during a measuring operation of the sensor.

Various embodiments include a method for operating an electrostatic particle sensor to detect the particle concentration in the exhaust gas of an internal combustion engine, the sensor comprising a first electrode, a second electrode electrically insulated from the first electrode by an insulating body, a guard electrode electrically insulated from the first electrode and from the second electrode by the insulating body, and a voltage supply. The method comprises: applying a first electric potential to the first electrode; applying a second electric potential to the second electrode; applying an guard potential to the guard electrode; and limiting a first leakage current flowing between the first electrode and the guard electrode via the insulating body to a first leakage-current limiting value using a first electrical limiting resistor arranged between the guard electrode and the voltage supply.

The present disclosure relates to actuators. Various embodiments may include a laminated magnet armature for an electromagnetic actuating device, an injection valve for metering a fluid, and/or an electromagnetic actuating device having a laminated magnet armature. For example, a laminated magnet armature for an electromagnetic actuating device wherein the magnet armature is displaceable along an axis A in a movement direction may include a multiplicity of interconnected laminations oriented perpendicular to the axis A and stacked to form a lamination stack with a bottom side and a top side. Each lamination includes at least one recess open toward an edge of the lamination. The laminations are arranged within the lamination stack so the recesses form at least one duct extending through the lamination stack from the bottom side to the top side.

The present disclosure relates to internal combustion engines. Various embodiments thereof may include a fuel injection valve for a combustion engine comprising: a valve body with a cavity; a valve needle movable in the cavity; an actuator assembly to actuate the valve needle. The actuator assembly includes an electro-magnetic coil, a pole piece positioned inside the cavity, and an armature element. The armature element moves within the cavity to move the valve needle in a predetermined direction. A fixing ring abutting the pole piece, fixed to the valve body by means of joining to a circumferential surface of the cavity.

The present disclosure relates to fluid injection and the teachings thereof may be embodied in an injector. Some embodiments include an injector comprising: a valve with a valve body and a valve needle; an armature mechanically coupled to the valve needle for moving the valve needle away from a closing position; and a damping element. The valve needle moves in the valve body and seals the valve. The armature displaces the valve needle away from the closing position. The damping element comprises: a hydraulic chamber and a piston arranged to modify a fluid volume of the hydraulic chamber. The piston reduces the fluid volume of the hydraulic chamber when the valve needle moves away from the closing position. A flow restricting orifice hydraulically connects the hydraulic chamber to the cavity.

A valve assembly for an injection valve is disclosed, including a valve body with a cavity, a valve needle axially moveable in the cavity, the valve needle being fixedly connected to a retaining element which extends in radial direction and is arranged in an axial region of the valve needle facing away from the fluid outlet portion, and an armature being able to slide on the valve needle and acting on the needle by way of the retaining element. A conical spring is arranged between the retaining element and a top side of the armature facing the retaining element, biasing the armature away from the retaining element.
