Abstract
A method for operating a fuel injection system and a fuel injection system for performing the method, in which the fuel is supplied in measurable amounts at high pressure to a high-pressure fuel reservoir, whose pressure is controlled by a pressure control valve and from which fuel is drawn for injection via electrically controlled injection valves. The system is monitored for leakage losses in that the fuel quantity supplied to the high-pressure fuel reservoir by a fuel pump and the quantity removed from the high-pressure fuel reservoir via the injection valves and the pressure control valve are compared with one another, and if these quantities deviate from one another a signal device is tripped, or an intervention into the operation of the fuel injection system is made.
