Abstract
A system for injecting fuel into the combustion chamber of a self-igniting internal combustion engine, has a control unit which acts upon a spring-controlled injection device which includes a nozzle needle, by way of which one or more injection openings are opened or closed. The control unit includes a first valve and a second valve, which each include one pressure chamber which communicate with one another via a pressure line. The first valve and the second valve are connected in series, and the first valve controls the subjection of the pressure chamber of the second valve to pressure, and the level of the injection pressure during the injection phases is controlled by the second valve.
