摘要： The invention relates to an electromagnetically actuatable fuel injection valve which is used to supply fuel to a mixture compressing internal combustion engine. The fuel injection valve comprises a valve housing provided with an extension in which a valve seat body is disposed. A magnetic coil is mounted on each of the pole parts and a permanent magnet is disposed between the poles of the pole parts. The valve seat body is connected to a guide via a collet. The guide, collet and valve seat body are penetrated by a valve needle which is connected at its one end to an armature and which, at its other end, ends in a closing end. In the guide is a guide bore which is adapted to radially guide a spherical head portion of the valve needle and which then tapers into an abutment face, against which face the valve needle rests by way of the head when the injection valve is open. To open the valve, the valve needle is moved outwardly, thereby uncovering an ejection opening between a valve seat and the closing head. The valve seat body and collet may be screwed together for the purpose of adjusting the valve stroke.

摘要： An electromagnetically actuatable fuel injection valve which serves to supply fuel to a mixture-compressing internal combustion engine having externally supplied ignition. The fuel injection valve includes a valve housing with a mouth piece, in which a valve seat body is disposed, included are two magnet coils two cores and one armature, which has a spherical guide section and the later is being connected to a valve needle. The spherical guide section is slidably supported with its circumference in a guide bore of the valve seat body and in its stroke movement away from the core is limited by a tapering stop opening which adjoins the guide bore. Flat faces are provided on the circumference of the spherical guide section, such that they decrease the area of contact between the spherical contact section and the stop opening.

摘要： An electromagnetically actuatable fuel injection valve which has an internal scavenging system for cleaning dirt particles from a magnetic field air gap. A portion of the fuel flowing in via an inflow line and an inflow opening reaches the vicinity of an air gap defined on one side by an armature and on the other by magnetic poles and flows through this gap, and then flows via an outflow opening to enter an outflow line that communicates with a fuel return. As a result of the described scavenging of the air gap, dirt particles are prevented from becoming firmly attached there and causing impairment of the performance of the fuel injection valve.

摘要： A temperature-dependent resistor or hot wire is extended over at least three anchoring points and to improve the measuring accuracy of the hot wire and to ensure sufficiently high temperatures over the entire active length of the hot wire during a cleaning step by burning, the hot wire is configured in the shape of loops at all anchoring points and the intersecting wire sections of the loops are conductively connected with one another. Current lead wires are preferably conductively attached to the hot wire by means of which the current is conducted to an electric control device. The end anchoring points are preferably electrically heated during an interruption of the measuring process of the hot wire and the hot wire may be directed in a W-shape over anchoring points whereat the hot wire is connected to the electric current, during the measuring process, via the two central, symmetrical anchoring points and upon an interruption of the measuring process, by means of a switching device, via the two end anchoring points.

摘要： A fuel injection apparatus for separately ignited internal combustion gas engines is proposed. The fuel injection apparatus comprises an air intake stack in which an injection valve is arranged upstream of a throttle valve. A ring slot developed approximately Venturi-shaped is formed between the casing of the injection valve and the cylindrical inner wall of the air intake stack. An air bypass line discharges into the narrowest cross-section of the ring slot developed approximately Venturi-shaped which begins upstream of the approximately Venturi-shaped ring slot. An air measuring organ with at least one temperature dependent resistance for measuring the air mass flowing through is arranged in the air bypass line. Downstream of the temperature dependent resistance the air bypass line has a section developed in the shape of a funnel into which a cone shaped brake body concentrically protrudes which is supported axially displaceable and through which not only an optimal output signal of the air measuring organ in dependence on the sucked in air mass can be adjusted, but a balancing of the characteristic curve of the air measuring organ can take place as well. The proposed fuel injection apparatus allows a compact construction which permits the accommodation in the engine room of the internal combustion engine of motor vehicles even with cramped conditions as well as a reliable method of operation.

摘要： A mixture formation system is proposed for mixture-compressing internal combustion engines with externally supplied ignition. The mixture formation system includes an air intake fitting in which an electromagnetically actuatable injection valve is held concentrically, upstream of a throttle valve. Disposed upstream of the injection valve is an air flow rate meter provided with a temperature-dependent resistor. The electronic regulating device of the air flow rate meter and a pressure regulator for regulating the fuel pressure at the injection valve as well as a supplementary air valve for controlling an air bypass bypassing the throttle valve during the warm-up phase of the engine may be provided on the air intake fitting. As a result, a mixture formation system is attained which is simply constructed and functions reliably, and which because of its compact structure can be accommodated in the engine compartment of an internal combustion engine even where space is extremely limited.
