摘要： A fuel injection system for internal combustion engines is proposed which serves the purpose of fuel injection into the air intake tube of the engine. The fuel injection system includes a fuel injection valve, which is supported upstream of a throttle valve in a holder body disposed coaxially in the air intake tube. A fuel supply line leads to the fuel injection valve, extending in a downwardly directed manner toward the fuel injection valve and away from a deaeration chamber. A fuel return line leads away from the fuel injection valve, extending in an upwardly inclined direction to discharge into the regulating chamber, disposed at a higher level, of a pressure regulating valve. A fuel feed line originating at a fuel supply pump terminates in an upwardly directed manner into the dearation chamber, which communicates via a dearation nozzle with the regulating chamber, so that vapor bubbles can escape upstream of the injection valve into the return side of the injection valve.

摘要： An electromagnetically actuatable fuel injection valve for fuel injection systems is proposed. The valve includes a valve housing and a first connection pipe serving as the core, which is surrounded by a magnetic coil. A second connection pipe is disposed inside the first connection pipe and with it forms a flow cross section for the inflowing fuel, which via the flow conduit can flow into an interior chamber of the valve housing surrounding the magnetic coil and from there can flow via a connecting line into a fuel chamber surrounding a nozzle needle, this chamber being defined by a guide bore in the nozzle body as well as by an injection port at one end and by an armature on the other. A bypass bore is provided in a head of the nozzle needle leading from this fuel chamber to an inner bore of the armature. This inner bore is open toward the second connection pipe so that at least a partial quantity of fuel is capable of flowing back via the second connection pipe.

摘要： An electric potentiometer is proposed which serves to convert a mechanical movement into an electrical value. The potentiometer includes a pickup embodied as a wiper and a resistor pad which has a plurality of connections for parallel resistors distributed over the displacement range of the pickup and serving as support points. With these parallel resistors, the partial resistance established by the pickup can be varied to a predetermined course. The support points extend crosswise to the contact track of the pickup on the resistor pad and are embodied as only so long that they terminate before reaching the contact track.

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.

摘要： A fuel injection valve is proposed for fuel injection systems of internal combustion engines, which serves to supply fuel into the intake tube of the engine. The injection valve includes a movable valve element which cooperates with a fixed valve seat, downstream of which are provided horizontal fuel guidance bores which discharge tangentially into a spin chamber. The spin chamber is disposed so that it widens conically in the flow direction. The fuel guidance bores simultaneously serve as metering bores. The spin chamber causes an axial speed component to be imparted to the fuel entering via the fuel guidance bores. As a result, the dwell time of the metered fuel within the spin chamber is short, and even in the case of quite short injection pulses, the fuel is still sufficiently well prepared.

摘要： A fuel injection valve and a method for the automatic establishment of the desired armature stroke of the fuel injection valve are proposed which serves the purpose of injection at low fuel pressures into the intake tube of a mixture-compressing internal combustion engine with externally-supplied ignition. The fuel injection valve includes a magnetic coil surrounding a core and a flat armature guided by at least one guide diaphragm held on its outer circumference, which is firmly connected with a movable valve element cooperating with a fixed valve seat. The fuel delivered via a fuel inlet nozzle can proceed through apertures and recesses in the guide diaphragms past the valve seat to a fuel discharge nozzle by way of which a portion of the delivered fuel can flow back again into a fuel return line. Via an annular channel the fuel stream exiting from the nozzle bore can be prepared with air which surrounds the fuel stream.

摘要： A fuel injection system is proposed for internal combustion engines having a plurality of injection valves for supplying fuel to the engine. Each injection valve is connected by a yieldable support bracket with a rigid fuel distributor line. The bracket is mounted pivotally with an annular coller secured to the injection valve. The fuel distributor line is arranged to engage rib-like carrier members connected with the internal combustion engine and is held against the carrier member by yielding clamp elements. After the valves are engaged in the sockets of the fuel distributor line and the bore of the cylinder head, then the support brackets are swung upwardly to tension the seal elements that are disposed in proximity to the opposite ends of the valve. As a result, not only a more secure connection between the fuel distributor line and the injection valves is obtained, but also rapid assembly or disassembly of the fuel injection system.

摘要： A fuel injection apparatus is proposed for mixture-compressing, externally ignited internal combustion engines which serves to apportion a quantity of fuel corresponding to the aspirated air quantity and to effect good preparation of the fuel-air mixture. The fuel injection apparatus comprises a fuel apportionment valve which is actuatable by means of an air flow rate meter arranged in the air induction tube of the internal combustion engine and an arbitrarily actuatable throttle valve arranged downstream of the air flow rate meter. The air flow rate meter has a circular control body, which is rotatably arranged on a bearing shaft with its outer circumference facing in the opposite direction to the air flow and, being transversely arranged with respect to the air induction tube, opens to a greater or lesser degree an aperture which defines the air induction tube cross-sectional area. The air flow rate meter is moved against a return force in accordance with the air quantity flowing therethrough.
