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 apparatus for externally ignited internal combustion gas engines is proposed. The fuel injection apparatus comprises an intake pipe in which an air flow meter and a throttle valve are provided. The fuel quantity injected into the intake pipe via an injection valve is controlled by the air flow meter. To prepare the combustible mixture of injected fuel and air, a preparation air line branches off from the intake pipe between the air flow meter and the throttle valve. This preparation air line discharges into the injection valve. A throttle is provided in the preparation air line. A full-load air line discharges into the preparation air line between the throttle and injection valve. A shut-off valve is provided in the full-load air line, said shut-off valve being completely open at least during the full-load operation of the combustion engine, allowing additional air flow into the preparation air line, which air is drawn from the intake pipe upstream of the air flow meter.

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 valve is proposed which, especially in low-fuel-pressure systems, serves to inject fuel into the intake tube of a mixture-compressing internal combustion engine with externally supplied ignition. The fuel injection valve includes a fixed valve seat cooperating with a movable valve element, downstream of which the fuel to be injected is carried into a mixture guidance channel of a mixture guidance tube and surrounded on all sides with air or exhaust gas for preparation immediately upon its entrance into the mixture guidance channel and injected via an injection opening into the intake tube. The mixture guidance channel may be embodied as tapering in conical fashion toward the injection opening. For the purpose of preliminary preparation of the fuel, secondary air or exhaust gas can already be delivered to the fuel before its entrance into the mixture guidance channel. The fuel injection valve embodied according to the invention assures optimal preparation of the fuel to be injected, even at low fuel pressures, and good running behavior of the engine in the event of abrupt changes in load.

摘要： A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes metering valves actuatable by means of an air flow measuring device, at which valves a pressure difference can be held constant via control valves and the pressure difference is variable in accordance with operational characteristics of the engine. To this end, the control valves are located on a control pressure line in which a control throttle and an electromagnetic valve are disposed. At the same time, pressure limitation elements communicate with the control pressure line and, in the event of acceleration of the engine, reduce the extent of increase of control pressure and thus assure fuel metering corresponding with the operational state of the engine.

摘要： A fuel injection system is proposed which serves for the improved conditioning of the fuel-air mixture fed to a mixture-compressing, spark-ignited internal combustion engine. The fuel injection system comprises preferably an injection valve at the air intake pipe wherein a conditioning member, pivotable by the amount of air introduced in opposition to a resetting force, is arranged downstream of an arbitrarily operable throttle element, this pivoting action being arranged to cause a pressure drop at the conditioning member. The fuel injection takes place through an injection valve disposed in an air bypass beyond the throttle element and the conditioning member. Due to the pressure drop produced by the conditioning member, it is ensured that, in all positions of the throttle element, a constant air stream is maintained via the air bypass, which serves for conditioning the injected fuel.

摘要： A fuel injection apparatus for mixture-compressing, externally ignited internal combustion engines. An air flow rate member, arranged in the air intake manifold is moved against a return force by air flowing through it to adjust a control slide of a metering and distribution assembly arranged in the fuel supply line in order to effect the apportionment of a quantity of fuel which is proportional to the air quantity. The return force is produced by a pressure fluid acting upon the control slide, the pressure of the fluid being variable in accordance with operating characteristics of the internal combustion engine. The control slide has an actuation slide contacting the air flow rate member as well as an apportionment slide, which has a projection with a smaller diameter projecting into an axial throttle bore of the actuation slide and defining a damping space in the throttle bore. The damping space is in communication with the fuel supply line via a gap between the projection and the throttle bore, and there is a bimetallic spring arranged between the apportionment slide and the actuation slide. By this means a richer fuel-air mixture is controlled at the metering and distribution assembly in accordance with the starting temperature, during starting of the engine below a predetermined temperature; the enrichment is lessened after the start in accordance with both temperature and time.

摘要： A bimetal device with an electrical heating element which serves for temperature-dependent control is provided. The bimetal device has a thin insulating layer, on which is arranged at least one electrical resistance layer which serves as a heating element. The resistance layer can be placed on the base of the bimetal device by means of vapor depositing or by thick film technology. In this manner a plurality of resistance layers can be provided that are insulated from each other and of which one serves for continual heating. It can also be useful to provide only one resistance layer which is connected in series with a PTC resistor and holds the bimetal device at a certain temperature. The embodiment of the electrical heating element as a resistance layer makes possible a very rapid heating of the bimetal.

摘要： A fuel supply and mixture generating system for an internal combustion engine includes an air flow rate meter and, downstream thereof in the induction tube, a pivoting throttle plate actuated from the outside. Pivoting on the same shaft as the throttle plate is a mixture generating plate having a damping wing which moves in the same direction as the throttle plate in an appropriately configured wall region of the induction tube and a mixture generator wing with internal fuel channels and one or more fuel injection orifices at the edge where it defines the air flow cross section. The mixture generating plate is displaced by the air stream and this displacement is opposed by a spring. At full throttle, the force of the spring is changed by interaction of the throttle plate with the point of attachment of the spring.
