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.
摘要翻译：提出了一种燃料喷射阀，特别是在低燃料压力系统中，用于将燃料喷射到具有外部点火供应的混合压缩内燃机的进气管中。燃料喷射阀包括与可动阀元件配合的固定阀座，下游将要喷射的燃料运送到混合引导管的混合引导通道中，并在空气或废气的所有侧面上被立即包围，以便立即进行准备其进入混合物引导通道并通过注射开口注入进气管。混合物引导通道可以以朝向注射开口的锥形方式变形。为了初步准备燃料，二次空气或废气在其进入混合物引导通道之前可以已经被输送到燃料。根据本发明实施的燃料喷射阀即使在低燃料压力下也确保了要喷射的燃料的最佳准备，以及在负载突然变化的情况下发动机的良好运行特性。

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 control apparatus is proposed for a fuel metering system of an internal combustion engine having at least one additively functioning warmup enrichment circuit. The apparatus is characterized in that the additive enrichment can be reduced during overrunning. The purpose of this feature is to maintain the cleanest possible exhaust gas even during the warmup phase during overrunning. This is attained, for instance, by means of a logical linkage of an overrunning recognition signal and the output signal of an additively functioning correction circuit for the metering signal.

摘要： A fuel supply system for internal combustion engines, in which a fuel injection valve is disposed upstream of a throttle device in an intake tube, from which valve a fuel stream which is asymmetrical relative to the throttle device emerges in order to influence the uniformity of mixture distribution to the cylinders of the engine. An asymmetrical fuel stream can be attained, by way of example, by inclining the fuel injection valve by a small angle (.alpha.) relative to the axis of the intake tube at the throttle device.
