Abstract

An injection system for a Diesel internal combustion engine which includes an injection pump with injection lines, injection valves with valve needles opening inwardly against spring pressure and leakage oil lines starting from the injection valve; a device consisting of a flow-direction sensor detecting the direction of flow and of a discharge valve is thereby arranged in each injection line, preferably in proximity of the injection valve, which discharges the pump volume of the injection valve resulting at the end of the injection operation into the leakage oil line.
