ABSTRACT:
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.
