摘要： An estimated value of the amount of fuel which is metered into a cylinder per working cycle is calculated. An estimated value of the indicated torque of the internal combustion engine is calculated as a function of the estimated value of the amount of fuel. An emergency operating mode of the internal combustion engine is actuated if the estimated value and a setpoint value of the indicated torque fulfill a predefined condition.

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 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.
