摘要： The invention relates to a method for adapting an injection valve characteristic curve of a controlled fuel injection valve for an internal combustion engine, said curve reflecting the reference injection behaviour, to alterations in the actual injection behaviour caused by ageing. According to said method: during an operating mode of the internal combustion engine, which does not require an injection of fuel, the injection valve is intermittently controlled in accordance with a control period, said mode alternating with a period of no fuel injection, i.e. at least one working cycle with injection-valve control follows or precedes a working cycle without injection-valve control; at least one respective RPM value of the internal combustion engine is detected for the controlled working cycle and for at least one of the working cycles without control; a differential between the detected values is calculated and said differential is used to correct the characteristic curve.

摘要： In fuel reservoir injection systems also known as common rail fuel-injection systems (1) for motor vehicles the problem exists that for a defined quantity of fuel that is about to be injected it is necessary to take into account not only the predominant pressure of the fuel but also its temperature. It is difficult to install and use a temperature sensor to detect the fuel temperature. The invention therefore proposes a method and a device for determining the temperature (T) from the pressure (P) measured by the pressure sensor (4) and the sound-propagation velocity (V) of a shock wave triggered at the moment of injection.

摘要： In a method for determining a vibration-optimised adjustment of an injection device of an internal combustion engine, for each cycle of the internal combustion engine, a plurality of individual injections per cylinder is carried out by the injection device, each of which is defined by a relative injection moment and an individual injection quantity. A temporal course of a resulting pressure influenced by pressure waves is determined in a fuel guiding part, and the above-mentioned adjustment is determined by variation of the injection moment of at least one individual injection and/or the individual quantity, such that the adjustment is characterised by a temporal variation of the resulting pressure, which is reduced by an at least partially destructive interference between the cited pressure waves. A corresponding device can determine a vibration-optimised adjustment of an injection device, and an internal combustion engine may have such a device.

摘要： A method and a device correct a temperature-dependent length change of an actuator unit (3) disposed in a housing (2) of a fuel injector (1). A known method of maintaining an idle stroke (L) formed between the actuator unit (3) and a control valve of the fuel injector involves compensating for a temperature-dependent length change by measuring the capacity of the actuator unit (3) and thereby determining the temperature (Ta). However, in the process an additional test impulse is used to trigger the actuator unit (3). Therefore, it is proposed to forego the use of a test impulse and to measure the capacity (CA-PA) directly at an active trigger impulse. The method is much more precise and reliable since the current operating parameters, such as fuel pressure, fuel temperature and actuation energy, among others, are taken into account.

摘要： A method for correcting the injection duration of injections is based on pressure fluctuations of preceding injections. The injection duration is determined on the basis of a mapping value and of a correction value. The mapping value is read out from a mapping according to the fuel pressure and according to the amount of fuel to be injected. The correction value is calculated according to the time interval between the subsequent injection and at least one latter injection. This enables a precise determination of the injection duration and thus a precise metering of the desired amount of fuel.
