    • A magnetic injection valve for injecting fuel into the intake tract of internal combustion machines, which is distinguished by particularly good internal cooling. A magnetic coil wound onto a coil carrier is located in the valve, being introduced into a valve housing and surrounds a ferromagnetic core. The core acts upon an armature which is connected to a movable valve needle. A bushing in the core and a sleeve located outside the core are arranged such that the fuel, emerging from an inflow tract of a supply device flows via the sleeve serving as a fuel line and reaches the interior of the valve housing that receives the magnetic coil; after flowing virtually completely around the magnetic coil, the fuel leaves this interior via a bore and flows back between the bushing and the core as far as the end of the bushing, and then flows on through the bushing to reach the armature to flow on to the valve seat. For better cooling of the magnetic coil, flow conduits are machined into the coil holder such that the fuel flow virtually surrounds the coil.

    • An electromagnetically actuatable valve which serves in particular to inject fuel into the intake tube of internal combustion engines operating with fuel injection systems. The fuel injection valve includes a valve housing, a shell core having a magnetic winding and a flat armature, which is firmly connected with a valve element which passes through a central guide opening in a guide diaphragm and cooperates with a fixed valve seat. The guide diaphragm has a fastening zone and together with the central guide opening cut out of a centering zone of the guide diaphragm guides the valve element in the radial direction toward the valve seat. The fastening zone is connected via struts with an annular guide zone on which the flat armature, under spring tension, rests with a concentric guide edge and is guided in a plane parallel to the end face of the shell core. The centering zone of the guide diaphragm is connected in turn via struts with the guide zone.

    • A method for preventing damage to a temperature-dependent resistor disposed in a flow cross-section caused by overheating as a result of the ignition of a combustible, gaseous mixture during a burnoff process and an air flow rate measuring device for performing the method are proposed. The air flow rate measuring device includes a temperature-dependent resistor disposed in a bypass line. Deposits on the surface of the temperature-dependent resistor are removed in a burnoff process, preferably following the opening of the ignition switch. The danger then exists that if the device is used in a motor vehicle, combustible fuel-air mixture located in the vicinity of the temperature-dependent resistor may ignite, and the temperature-dependent resistor would thereby be destroyed because of overheating. For this reason, a slide member is pushed into the flow cross-section during the burnoff process, so that only a small combustible volume is available in the vicinity of the temperature-dependent resistor.
    • 提出了一种用于防止由于在燃烧过程中燃烧的气体混合物的点燃而引起的由过热引起的流动横截面中的温度依赖电阻的损坏的方法和用于执行该方法的空气流量测量装置 。 空气流量测量装置包括设置在旁路管线中的温度依赖电阻器。 在燃烧过程中,优选在点火开关打开之后,在温度依赖性电阻器的表面上的沉积物被去除。 因此存在如下危险:如果该装置用于机动车辆中,位于温度敏感电阻附近的可燃燃料 - 空气混合物可能会点燃,因此温度依赖性电阻器将由于过热而被破坏。 因此,在燃烧过程中,滑动构件被推入流动横截面,使得在温度依赖性电阻器附近只有小的可燃体积可用。

    • A lambda regulating device is proposed for a fuel metering system in an internal combustion engine with externally supplied ignition. In addition to the regulation means which is already present, multiplicative and additive corrective variables are formed and are stored in non-transient memories. The regulating device enables an additive regulated shutoff of the additive lambda shift during idling and in the lower partial-load range, and it also enables regulation to a symmetrical distance on the part of the regulating manipulation from the limitation. The additive correction may be selected to be in accordance with rpm. Finally, the reference variables for the corrective value may be selected depending upon the air throughput in the intake tube of the engine. With a view to realization of the invention by means of a computer, individual flow diagrams relating to the mode of operation are given in the drawings.

    • A fuel supply system is proposed for mixture-compressing internal combustion engines having externally supplied ignition. The fuel supply system includes an air intake tube delimited by an air filter, the air intake tube having a conical section downstream of which an arbitrarily actuatable throttle device is disposed. Associated with the conical section of the air intake tube is an air bypass line in which an air flow rate meter provided with a temperature-dependent resistor is disposed. The quantity aspirated by the engine is determined by this air flow rate meter. A fuel injection valve is disposed in such a manner that on one side it protrudes into the interior of the air filter and on the other side, with a slender mouthpiece, it protrudes approximately through the conical section. The fuel can be injected into the gap between the throttle device and the air intake tube wall by means of this mouthpiece. The fuel supply system according to the invention has a very low structural height.
    • 提出一种燃料供应系统,用于混合压缩具有外部点火的内燃机。 燃料供给系统包括由空气过滤器限定的进气管,进气管具有下游的锥形部分,其中设置有可任意启动的节流装置。 与进气管的锥形部相关联的是配置有温度依赖性电阻器的空气流量计的空气旁通管路。 发动机吸气量由该空气流量计确定。 燃料喷射阀以这样的方式设置,使得其一侧突出到空气过滤器的内部,而在另一侧上具有细长的接口,其大致突出通过锥形部分突出。 燃料可以通过该接口管喷射到节流装置和进气管壁之间的间隙中。 根据本发明的燃料供应系统具有非常低的结构高度。
