Abstract
A common rail fuel injection system in which the pressure in the return line is controlled as a function of the delivery pressure of the presupply pump. This improves the operating behavior of a high-pressure fuel pump and the injectors which are supplied with fuel by means of a common rail. The pressure in the return line is controlled by means of a pressure control valve.
