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： An injection system for internal combustion engines is proposed, in which once the engine has been turned off, a pressure equalization is established between the intake side and the pressure side of the high-pressure fuel pump. This prevents uncombusted fuel from reaching the combustion chambers of the engine. The pressure prevailing on the pressure side and the intake side when the engine is off furthermore assures that vapor bubbles cannot form, and this makes starting the engine easier.

摘要： The invention is directed to a method and an arrangement for operating a fuel supply system (10) and especially a fuel supply system of an internal combustion engine of a motor vehicle. Fuel is pumped into an accumulator (19) with the aid of pumps (13, 24) and the fuel is adjusted at least to a first pressure (P1) or a second pressure (P2). Initially, the first pressure (P1) is adjusted and a pressure signal (PS1) is detected and, thereafter, the second pressure (P2) is adjusted and a pressure signal (PS2) is detected. A pressure difference (&Dgr;P) is formed from the detected first and second pressure signals (PS1, PS2). If the pressure difference &Dgr;P deviates from an expected pressure difference (&Dgr;P_E) by more than a threshold value (S), then a fault in the fuel supply system (10) is detected and stored.

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： 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.
