ABSTRACT:
A fuel injection valve which serves in low-pressure fuel systems to inject fuel into the intake tube of a mixture-compressing internal combustion engine having externally-supplied ignition. The fuel injection valve includes a fixed valve seat cooperating with a movable valve element. Downstream of the valve seat, the fuel to be injected proceeds by way of a nozzle into a mixture guidance conduit, which communicates in the immediate vicinity of the nozzle with an intake passage downstream of a throttle valve of the intake passage. Likewise discharging at the mouth of the mixture guidance conduit into the intake passage is an annular conduit surrounding the mixture guidance conduit. Preparation air or exhaust gas can be delivered by way of this annular conduit in such a way that it envelops the injected fuel on all sides. The end of the annular conduit discharging into the intake tube is embodied as a throttle restriction. The embodiment of the fuel injection valve according to the invention assures good preparation of the fuel to be injected, while simultaneously avoiding an undesired leaning down of the fuel-air mixture delivered to the engine.
