The present invention relates to an injector for injecting fuel, comprising an injector housing, a movable nozzle needle which is arranged in the injector housing and has a nozzle needle tip, a nozzle needle seat for receiving the nozzle needle tip, and a mechanical switch which upon contact of the nozzle needle tip with the nozzle needle seat assumes a closed state and upon interruption of the contact assumes an open state, wherein the injector is provided with an input line and an output line for actuating a movement of the nozzle needle, and the switch includes a first terminal and a second terminal. The injector is characterized in that the first terminal of the switch is connected to the input line and the second terminal of the switch is connected to the injector housing.

A fuel injector assembly includes a valve housing, a valve stem that is disposed in the valve housing, a magnetic coil that surrounds the valve housing and is used to displace the valve stern within the valve housing, and a terminal blade. The terminal blade includes a bus bar that provides an electrical connection between the magnetic coil and an external connector. In addition, the terminal blade includes a clip that is connected to the bus bar at a clip first end and to the valve housing at a clip second end. The clip includes a sacrificial portion that is configured to part, for example by dissolving, when the terminal blade undergoes an overmolding process. As a result of the overmolding process, the clip is separated into multiple, spaced portions.

An electromagnetic positioning device includes an armature member for actuating a positioning partner and movable in an armature space relative to a stationary core (30). The armature member conducts magnetic flux upon energization of a stationary coil (32). The coil has a coil support with a winding and at least one external contactable connector (46) embedded at least in sections in the core and/or surrounded by the core. The core has an end surface (34), which is planar at least in sections, for interacting with the armature member. The core and the coil are embedded in and/or surrounded by a one-piece pot-like and/or cup-like housing (38) made of a material suitable for deep-drawing in such a manner that the core rests on a membrane-like, continuous and closed base section of the housing, the base section realizing a boundary surface of the armature space.

An electronic fuel injection throttle body unit has a core body with two side components. The two side components each including a fuel delivery passage. Four air intake passages extending vertically through the throttle body. Valves are rotatable within the air intake passages. The valves being connected to valve shafts that rotate about respective valve shaft axes. The valve shaft axes and the fuel delivery passages are perpendicular to each other.

A fuel injector includes an injector housing defining a longitudinal axis, and including a body piece having formed therein a fuel inlet defining a transverse axis intersecting the longitudinal axis. The injector housing further includes a nozzle having formed therein a plurality of spray outlets, and including a nozzle terminal tip. The injector housing further includes a locating surface axially inward of the nozzle terminal tip and extending circumferentially around the nozzle. A first axial distance (AD) is defined between an intersection of the transverse axis and the longitudinal axis, and the nozzle terminal tip. An exposed tip length axial distance (TL) is defined between the locating surface and the nozzle terminal tip. A ratio of AD to TL is from 8.06 to 8.34.

A fuel injector includes an injector housing having a fuel connector, and an outer housing surface extending around a longitudinal axis of the injector housing. The outer housing surface includes a cylindrical upper section, a cylindrical lower section, and a middle section. The fuel connector defines a connector axis oriented normal to a longitudinal axis of the injector housing and extending between a first connector end attached to the middle section, and a terminal connector end radially outward of the outer housing surface and having therein a fuel inlet. The fuel connector includes an outer connector surface having an unthreaded base section, and an externally threaded end section adjacent to the terminal connector end.

A fuel injector includes an injector housing defining a longitudinal axis extending between a first axial injector end and a second axial injector end. The injector housing includes an upper body piece forming the first axial injector end and including a fuel connector defining a connector axis intersecting the longitudinal axis. The injector housing further includes a nozzle having formed therein a plurality of spray outlets, and including a nozzle terminal tip. An injector full diameter (FD) is defined by the upper body piece. An axial distance (AD) is defined between an intersection of the connector axis and the longitudinal axis, and the nozzle terminal tip. A ratio of AD to FD is from 4.8 to 5.1.

This fuel includes: a first switching element disposed between a booster circuit boosting a battery power and one end of a solenoid; a second switching element disposed between a battery and one end of the solenoid; a third switching element disposed between the other end of the solenoid and a ground; a fourth switching element disposed between one end of the solenoid and a ground; and a control unit configured to control open/closed states of the first switching element, the second switching element, the third switching element, and the fourth switching element. The control unit is configured to open the fourth switching element during a valve closing detection period of detecting closing of a fuel injection valve and to detect the closing of the fuel injection valve on the basis of a change in voltage of the other end of the solenoid.

A flame arrestor screw for a solenoid operated gas admission valve. The flame arrestor screw may include a screw body having a first end and an open end. The flame arrestor screw may include a gas passage extending from the open end along a longitudinal axis of the screw body and terminating at a terminal end within the screw body. A through hole may extend through the screw body transverse to the gas passage and in fluid communication with the gas passage.

Various embodiments of the teachings here include a fixing bracket for fixing a tie wrap at a fuel rail for mounting a wiring harness at the fuel rail, the fixing bracket comprising: a one-piece bracket body extending along a longitudinal direction, the bracket body including a first longitudinal end section, a second longitudinal end section, and an intermediate section. The intermediate section is disposed between the first end section and the second end section. The intermediate section comprises a protrusion including two bows spaced apart from one other by a slot disposed between the bows.
