摘要： Apparatuses for the injection of a fuel-gas mixture that have a cup-shaped gas enveloping sleeve that surrounds a valve end of a fuel injection valve, in which the base of the gas enveloping sleeve rests directly on a valve end of the fuel injection valve, have already been proposed. In such apparatuses, the danger is that the perforated body, which has injection ports, will be damaged during installation of the gas enveloping sleeve. In the novel apparatus, however, an elastic sealing element is disposed in the direction of the longitudinal valve axis between the valve end of the fuel injection valve and an end of the base portion of the gas enveloping sleeve that faces the valve end. This sealing element lessens the danger of deformation of and damage to a perforated body, having injection ports, of the fuel injection valve at the valve end and makes it possible to compensate for production and installation tolerances. The proposed apparatus for injecting a fuel-gas mixture is especially suitable for mixture-compressing internal combustion engines having externally supplied ignition.

摘要： A device for the injection of a fuel/gas mixture is particularly simple and cost-effective for gas containment of fuel emerging from an injection valve. For this purpose, a treatment attachment is provided at the downstream end of the injection valve, the treatment attachment including at least a gas containment part and an insert body which are fixedly connected to one another. The treatment attachment is fixedly connected to the injection valve by means of a casing portion of the bowl-shaped gas containment part, while a bottom portion of the gas containment part has material of the insert body at least partially injection-molded around it. Inside the insert body extends an orifice which at least partially widens conically in the downstream direction and in which, for example, a jet divider is arranged. The device is particularly suitable for injection into the suction pipe of a mixture-compressing spark-ignition internal combustion engine.

摘要： A valve for injecting a fuel/gas mixture that includes a perforated body, which comprises an upper thin plate and a lower thin plate, both of which are for instance embodied of monocrystalline silicon. At least one conduit is formed between the upper thin plate and the lower thin plate, by way of which conduit the gas meets the fuel injected through the at least one injection port. It is unnecessary to adjust the metered gas quantity. The perforated body and the valve are particularly suitable for injection systems in mixture-compressing internal combustion engines with externally supplied ignition.

摘要： An apparatus for injecting a fuel-air mixture, including a cup-shaped gas delivery hood with a bottom part of a jacket part between the valve end of a fuel injection valve and a gas delivery element, the jacket part has at least one gas delivery opening through which gas is injected and which strikes the injected fuel. The size of the opening cross section, which meters the gas, of the at least one gas delivery opening is accordingly fixed from the very outset and need not be adjusted. Moreover, because of a directional flow of the delivery of gas, very good atomization of the fuel is attained. The embodiment of the apparatus is especially well-suited for use in mixture-compressing internal combustion engines with externally supplied ignition.

摘要： A fuel injection valve including a perforated silicon plate disposed downstream of a valve seat and having an atomization opening that widens in the flow direction. The perforated silicon plate has at least one elongated recess on an upper end face oriented toward the valve seat face; this recess at least partly overlaps a metering opening extending as far as a lower face end of the perforated plate. The perforated plate makes it possible to form flat streams, so that very fine atomization of the injected fuel is attained. Forming the elongated recesses and atomization openings by etching makes high-precision manufacture possible at low production cost. The perforated plate and fuel injection valve are especially suitable for injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

摘要： A fuel injection valve for injecting a fuel-gas mixture into a mixture-compressing internal combustion engine with externally supplied ignition comprising a mixing conduit secured to one end of the fuel injection valve. The mixing conduit includes at least one cross-sectional constriction and an adjoining widening of the cross-section, through which the fuel-gas mixture flows at increased speed which tears off the fuel film from the wall of the mixing conduit and atomizes it into fine fuel droplets. In this way, the quality of fuel atomization can be substantially improved.

摘要： In known fuel injection valves, a perforated disk having metering openings is disposed downstream of the valve seat. Adjusting the static fuel quantity injected during the steady opening state of the fuel injection valve is accomplished by means of the precise manufacture of the metering openings. Despite the high expense and effort of manufacture, an undesirably high deviation in the static fuel quantity of the various fuel injection valves occurs in mass production. The static fuel quantity is adjusted directly at the completely assembled fuel injection valve, so that the deviation of the static fuel quantity of the various fuel injection valves is minimized. To this end, the valve housing and the perforated disk are moved relative to one another, and as a result the various free flow cross sections of the metering openings are varied until the injected fuel quantity flow match the required fuel quantity flow. The method according to the invention is suitable for fuel injection valves of various types.

摘要： A perforated plate that provides an improvement in a fuel injection valve that is used to inject fuel into the intake tube of a mixture-compressing internal combustion engine having externally supplied ignition. The perforated plate is secured on a nozzle body of a fuel injection valve, in which a tight-seat face is embodied. Cooperating with the tight-seat face is a valve needle, to which an armature is secured, which is actuated electromagnetically by a magnetic coil. The perforated plate is secured downstream of the tight-seat face, and is provided with opposite disposed elongated indentations each of which slope toward and discharge into a cylindrical hole in order to form fanlike streams that are ejected through the cylindrical hole.

摘要： Orifice elements for use in valves for injecting fuel or a fuel-gas mixture. The orifice elements include two silicon plates, joined to one another. An upper plate has one or more injection orifices. The lower plate has a through hole introduced in it, through which a fuel jet can emerge. The lower plate follows in the downstream direction and includes a jet splitter. The jet splitter divides the through hole into at least two passthrough openings so that a dual-jet characteristic is produced or maintained for the valve. At least two conduits are formed between the upper plate and the lower plate. Gas is provided via the conduits and is mixed with the fuel discharged through the injection orifice. The injection orifice and the valve are particularly suited for injection systems of mixture-compressing internal-combustion engines having externally supplied ignition.
