ABSTRACT:
A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes an intake manifold having a measuring device arranged therein which is moved against a restoring force in accordance with the quantity of air flowing therethrough and thereby actuates the control slide of a distribution valve. The restoring force on the air flow measuring device is actuated by fuel, supplied by a fuel pump via a damping throttle, which operates within a pressure chamber into which the control slide protrudes by means of an end face. A check valve is arranged in a discharge line between the pressure chamber and the delivery side or the suction side of the pump, and opens above a predetermined pressure within the pressure chamber. This allows a rapid unloading of the pressure chamber and a rapid response of the fuel injection system in the case of an acceleration.
