    摘要: An injection valve has a magnetic actuator and an injector needle able to be moved axially by the magnetic actuator. To meter a fluid by the injection valve the magnetic actuator is activated for an individual metering process with at least one actuation signal with a first or second signal waveform. The two actuation signals differ from one another in that, on activation of the magnetic actuator by the actuation signal with the first signal waveform, less energy is transmitted to a magnet unit of the magnetic actuator than during activation of the magnetic actuator by the actuation signal with the second signal waveform. The magnetic actuator is activated by the actuation signal with the second signal waveform if an activation of the magnetic actuator by the actuation signal with the first signal waveform leads to an undesired premature closure of the injector needle.

    摘要: In a first operating state, the fuel metering of one of the cylinders is controlled in first metering pulses with the same pulse characteristic during a respective one working cycle, and the metering of fuel into the other cylinders by at least one second metering pulse with a different pulse characteristic. The first pulse number and characteristic is predefined such that the same fuel mass should be metered based on an assumed injection valve characteristic as with the one second metering pulse. Depending on the measurement signal, a correction value for the one cylinder is determined. To meter the fuel based on the assumed injection valve characteristic, a single first metering pulse would be generated during a respective one working cycle. The correction value for the one cylinder is used during the rest of the operation to adapt the first metering pulse in the second operating state.

    摘要: In order to reduce the quantity deviation of a fuel injection valve, it is proposed according to the various embodiments that a test injection be carried out during an overrun cut-off phase of a motor vehicle in operation. In the process, the fuel rail (2) is closed on the inlet side and the selected injection valve (1) is activated. A quantity difference between the predetermined setpoint and the actual value can be determined by measuring a pressure difference in the fuel rail (2) before and after the test injection. This results in a correction factor with which the activation for the selected injection valve (1) is corrected for subsequent injections.

    摘要: The invention relates to a method for operating an internal combustion engine comprising a fuel pressure accumulator, in order to provide fuel at a nominal pressure, pressure in a fuel pressure accumulator being generated by means of a high-pressure pump. According to said method, the high-pressure pump is supplied with a fuel flow via a volume flow control valve. In a first operating mode, the pressure in the fuel pressure accumulator is set to the nominal pressure, by regulating the fuel flow of the fuel delivered to the high-pressure pump by means of the volume flow regulating valve. In a second operating mode, the pressure in the fuel pressure accumulator is set to the nominal pressure, i.e. more specifically, the pressure in the fuel pressure accumulator is reduced to the nominal pressure.
