Abstract
A fuel-injection system comprises a control unit that controls the injection of a fuel cylinder of an engine such that an injection volume of the fuel is injected into one of the cylinders during each work cycle of the engine. To this end, the control unit actuates an inlet valve and/or outlet valve such that, during pump strokes of a high-pressure pump which follow one another, a different high-pressure volume of the fuel per pump stroke is delivered into a pressure accumulator during at least two consecutive work cycles. The high-pressure volume that is produced per work cycle corresponds to the injection volume that is removed from the pressure accumulator per work cycle and is constant during each of the consecutive work cycles.
