摘要： In a process for regulating the injection quantities of injectors which are fluidically connected with a common pressure line in a common-rail injection system of an internal-combustion engine, a fuel pump provides fuel in the pressure line under a static nominal pressure. Control signals for opening and closing within individual injection periods for achieving respective identical injection quantities are supplied to the injectors by a regulator unit. In the case of different flow rates of the individual injectors respective identical injection quantities are achieved by the regulator unit by changing the respective injection period on the basis of a measuring signal. For this purpose, a pressure gauge inserted into the pressure line generates a measuring signal from a measurement of the static measuring pressure in the pressure line in each case after the closing of an injector. From the difference between the nominal pressure before the injection and the differential pressure after the injection, the regulator unit determines the fuel quantity taken from the pressure line during the injection. In case of a deviation from a known desired value, the regulator causes a corresponding change of the injection period of the diagnosed injector.

摘要： In a method of controlling the operation of an internal combustion engine with fuel injection by way of a common high pressure (common rail) fuel supply line to which high pressure fuel is supplied by a high pressure fuel pump and from which fuel is admitted to the various cylinders of the internal combustion engine by valve controlled fuel injection nozzles, the fuel pressure in the common fuel supply line between the end of an injection and the start of a fuel supply period is monitored at distinct timely spaced measurement points and, if a pressure difference between the measurement points is sensed in excess of a predetermined limit value indicating an injector malfunction, the high pressure fuel supply to the common fuel supply line is interrupted by deactivating the high pressure fuel pump while fuel injection through the operative nozzles is maintained so as to rapidly reduce the pressure in the common fuel supply line.

摘要： A arrangement for determining the injection course in an internal combustion engine in which the injection development could not be used heretofore in practice as guide magnitude in the engine control because no stationary measuring sensors are available for the pressure in the injection valve and a through-flow measurement at the feed line to the injection valve is very inaccurate by reason of the occurrence of gas, respectively, vapor bubbles. According to the present invention, the pressure in the injection valve, respectively, the quantity or the flow of the occurring injection medium is derived by a computer from signals of measurement transmitters which determine the stroke of the closure element of the injection valve and the pressure in the feed line to the injection valve or the force with which the closure element of the injection valve abuts in its open end position at an abutment.

摘要： A fuel system includes a fuel rail that communicates fuel at a first pressure through a fuel amplifier to a fuel injector. The fuel pressure amplifier increases the pressure from the first pressure to a second pressure. The second pressure is higher than the first pressure and is communicated through each of the plurality of fuel injectors. The fuel amplifiers provide for the application of fuel pressure without the need to configure each and every fuel system component for the corresponding higher pressures.
