An electromagnetic positioning device having anchor means which are realized for actuating a positioning partner and which are movable in an anchor space relative to stationary core means (30), which conduct magnetic flux, as a reaction to an energization of stationary coil means (32), the coil means, which have a coil support (32) provided with a winding and at least one external contactable connector (46), being embedded at least in sections in the core means and/or being surrounded by said core means and the core means realizing an end surface (34), which is planar at least in sections, for interacting with the anchor means, wherein the core means and the coil means 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 means rest on a membrane-like, continuous and closed base section of the housing, the base section realizing a boundary surface of the anchor space.

Examples are provided for switching an engine fuel supply. One example system includes a direct-injection engine including a cylinder, an LPG tank for storing a LPG fuel, a CNG tank for storing a CNG fuel, a gas switching valve, a high-pressure pump connected between the LPG tank and the gas switching valve, a pressure-limiting valve connected between the CNG tank and the gas switching valve, a fuel distributor configured to be supplied with one or more of the LPG fuel and the CNG fuel via the gas switching valve, an LPG injection valve coupled to the cylinder, a CNG injection valve coupled to the cylinder, the LPG injection valve and the CNG injection valve configured to be supplied with fuel via the fuel distributor; and a controller configured to control the gas switching valve depending on an aggregate state of the fuel disposed in the fuel distributor.

The invention relates to a device for sensing the state of an injector, comprising an injector for injecting fuel into an engine combustion chamber, a switch, which is designed to change the switching state thereof in accordance with the state of the injector, and an evaluating unit for sensing the switching state of the switch, wherein a first switch contact of the switch is connected to an electrical input line of the injector, a second switch contact of the switch is connected to ground, and the evaluating unit is designed to carry out a first current measurement for a current flowing into the injector and into the switch and a second current measurement for the current flowing into the injector.

A fuel delivery injector includes a housing, an inlet port fluidly coupled to a cavity to direct fuel vapor and liquid fuel into the cavity, and an outlet port fluidly coupled to the cavity to direct fuel vapor and liquid fuel out of the cavity. A magnetic assembly is fixedly positioned within the cavity, and a pumping assembly includes a bobbin and a piston. A return spring is coupled to the pumping assembly to bias the pumping assembly to a home position. A valve is positioned within the piston and is movable between an open position and a closed position. The liquid fuel entering the housing through the inlet port flows from the inlet port to the cavity and fuel vapor entering the housing through the inlet port is directed through a conduit to the outlet port.

An engine including a common rail attached to one side portion of a cylinder block that pivotally supports a crankshaft in a rotatable manner, the one side portion extending along a crankshaft center, and the common rail being configured to supply a fuel to the engine. A flywheel housing that accommodates a flywheel that is rotated integrally with the crankshaft is disposed in one side portion out of opposite side portions of the cylinder block intersecting the one side portion. One end portion of the common rail is disposed above the flywheel housing.

The housing includes a first cylinder part having a first end connected to a nozzle, a second cylinder part having a first end connected to a second end of the first cylinder part and forming a magnetic throttle part in at least a part of the second cylinder part in an axial direction, a third cylinder part having a first end connected to a second end of the second cylinder part, and a fuel passage formed inside the first cylinder part, the second cylinder part, and the third cylinder part so as to communicate with injection holes and guide the fuel to the injection holes. A yoke has a cylindrical shape, of which the first end side is connected to the first cylinder part and the second end side is connected to the third cylinder part, and is provided on a radially outer side of the housing such that an axial force is generated in the first cylinder part and the third cylinder part in a direction in which the first cylinder part and the third cylinder part approach each other.

A device that is used for the electrical connection of a control cable to a plurality of injection valves includes a connecting plug to which the control cable can be plugged, and a plurality of contact points at each of which an electrical connection to one of the injection valves is enabled. Electrical lines are routed from the connecting plug to the contact points, and, at least in come segments the routing is through a housing. The connecting plug has a connecting plug receptacle and a plug element that, in the installed state, is plugged into the connecting plug receptacle and that receives ends of the electrical lines.
