摘要： A method for operating an injection valve of an internal combustion engine, whereby the metering of fuel is adjustable in particular by varying the stroke of the nozzle needle of the injection valve, makes it possible to prevent an incomplete closure of the valve due to soiling (the risk of damage caused by a gasoline-filled cylinder) in operating states of the internal combustion engine in which no complete strokes of the nozzle needle occur over a prolonged period of time and the nozzle is therefore not sufficiently scavenged. The nozzle is scavenged with fuel when a jammed-open operating state of the nozzle needle is detected.

摘要： In an internal combustion engine, the fuel enters at least one combustion chamber of the internal combustion engine via at least one fuel injection device. A piezoelectric actuator moves a valve element of the fuel injection device. The function of the piezoelectric actuator is monitored and a malfunction is detected. To minimize the risk of damage to the internal combustion engine in the event of a malfunction of the piezoelectric actuator, the fuel mass flow to the fuel injection device is reduced if a malfunction of the piezoelectric actuator is detected.

摘要： A fuel delivery system for an internal combustion engine, having a fuel feed pump, which delivers fuel which is at pilot pressure to a high-pressure fuel pump that communicates on the high-pressure side with at least one injection valve, in order to deliver fuel at high pressure to the injection valve or valves. To prevent vapor bubble development in the high-pressure fuel pump, which impairs its pumping capacity and pressure generation, a coolant medium flow can be delivered to the high-pressure fuel pump via at least one coolant conduit, in order to keep the temperature (THDP) of the high-pressure fuel pump below a critical operating temperature (Tk1).

摘要： The invention relates to a method and an arrangement for calibrating a pressure sensor (7) of a fuel-metering system of an internal combustion engine wherein the fuel-metering system includes: a high-pressure pump (2) for pumping fuel from a low-pressure region (ND) into a high-pressure region (HD) injectors (5) for metering the fuel from the high-pressure region (HD) into combustion chambers (6) of the internal combustion engine with the injectors (5) being drivable in dependence upon operating characteristic variables, and the pressure sensor (7) for measuring the pressure in the high-pressure region (HD). To calibrate the pressure sensor (7) so that the offset error is minimized, it is suggested that a pressure, which is present in the high-pressure region (HD), is applied as a reference pressure; that the pressure, which is present in the high-pressure region (HD), is measured as the sensor pressure by the pressure sensor (7); and, that the characteristic line of the pressure sensor (7) is so corrected that the difference of reference pressure and sensor pressure is minimized.

摘要： Method for varying a prepressure (p_des) generated by a low-pressure pump and applied to a high-pressure pump with the low-pressure pump (2) and the high-pressure pump (3) pumping fuel for the internal combustion engine (1). In order to keep the prepressure (p_des), on the one hand, as low as possible to take load off the low-pressure pump (2) and to, on the other hand, adjust the prepressure (p_des) so high that a vaporization of the fuel is reliably avoided, the invention suggests that: the actual temperature (T_Krst) of the fuel in the high-pressure pump (3) is determined; a prepressure (p_des) as low as possible is determined in dependence upon the fuel temperature (T_Krst) for which a vaporization of the fuel in the high-pressure pump (3) is reliably avoided; and, the low-pressure pump (2) is so driven or controlled that it generates the determined prepressure (p_des). The method is preferably carried out on the basis of physical models of the high-pressure pump (3).

摘要： The invention relates to a method for reducing the fuel pressure in a return-free fuel supply system of an internal combustion engine to a desired pressure value. At least one fuel pump is mounted in the fuel supply system. In order to be able to reduce the fuel pressure in the fuel supply system in a simple manner without additional pressure release valves, the suggestion is made that the fuel supply system and the internal combustion engine be operated in a pressure-reduction mode wherein at least one fuel pump of the fuel supply system is so controlled (open loop and/or closed loop) that the desired pressure value is adjusted in the fuel supply system. The fuel supply system is preferably configured as a common-rail storage injection system for a direct-injecting internal combustion engine.

摘要： The invention relates to a method for forming a fuel-air mixture and to a fuel supply device for an internal combustion engine, having an intake manifold, into which an air intake tube with an aspirated air metering device disposed in it discharges and to which the intake tubes leading to individual combustion chambers are connected. A plurality of fuel injection valves are provided, each of which is assigned to one combustion chamber, and having a central fuel vaporizer to which fuel can be supplied by means of a fuel metering device. To form a fuel-air mixture, the fuel to be supplied to the engine is vaporized and the fuel vapor is supplied to the aspirated air. In order to lower pollutant emissions after starting during the warmup phase of the engine, vaporization of the fuel is done at relatively low temperatures, so that the fuel vapor produced essentially comprises only highly volatile fuel components. The fuel vapor produced by the fuel vaporizer in a vaporization region is supplied, downstream of the aspirated air metering device to the air aspirated by the combustion chambers in order to form a fuel-air mixture.
