The fuel injection system has least one magnet valve for controlling the fuel injection. The magnet valve is triggered by an electric control unit and has a magnet coil, a movable pistonlike magnet armature by which a valve member is movable between at least two positions, a magnetic disk by which the magnet armature is attracted when current flows through the magnet coil, and a cup-shaped capsule into which the magnet armature dips. The magnet armature is guided at least indirectly displaceably via its outer jacket in the capsule.

Fuel injection device for an internal combustion engine

The invention relates to a quantity control valve for a fuel injection system, used in internal combustion engines, which includes a longitudinal slide that is movable in a valve housing between a first and a second control chamber and that allocates the fuel, flowing in from at least one low-pressure pump, to at least one high-pressure pump. For driving the longitudinal slide, the inflowing fuel is delivered into the first control chamber via a throttle or baffle valve, past the longitudinal slide. In the second control chamber, there is either a restoring spring that urges the longitudinal slide in the direction of its closing position, or the longitudinal slide there has an effective face-end surface area upstream of which a control line containing a throttle valve ends; this end face is smaller in surface area than the effective surface area of the face end in the first control chamber. In the closing position, the longitudinal slide blocks off the outlet bore with one of its cylindrical guide portions, while with regard to the inlet bore it has a narrowed region, which opposite the longitudinal slide bore leaves a flow cross section open that changes gradually to zero in the direction of the guide portion. In the valve, the flow of fuel is controlled by a targeted manipulation of a cross section via a long slide stroke.

Fuel injection system for internal combustion engines

A cylinder head cover of an internal combustion engine with a solenoid-controlled injection device using pump-nozzle units designed so that the solenoid valves are supplied with power in a manner that is advantageous from the manufacturing point of view and provides reliable operation. For this purpose, the cylinder head cover covers the entire injection device and contact elements designed as inserts are injected into the cylinder head cover made of plastic in an injection molding process. The contact elements automatically come into a close-fitting contact with contact surfaces mounted on the outside of the solenoid valves when the cylinder head cover is mounted on a cylinder head. The contact elements are combined with contact segments in a central connector mounted on the outside of the cylinder head cover, wherein the power is supplied for the solenoid valves centrally from a controller.
