摘要： A method for operating an internal combustion engine having a fuel pump with a drive shaft is provided, the fuel pump conveying fuel into at least one fuel-collection line, the fuel being subsequently conveyed to at least one combustion chamber via at least one fuel-injection device. In the method, a quantity of the fuel conveyed by the fuel pump into the fuel-collection line is set by means of a valve device. The valve device is configured to selectively connect a discharge side of the fuel pump to a low-pressure region of the fuel pump (during deactivation phase), and selectively disconnect the discharge side from the low-pressure region (during supply phase). In supplying the quantity of fuel, a supply rate, defined as the number of supply phases of the fuel pump per rotation of the drive shaft, is determined as a function of at least one operating parameter of the internal combustion engine.

摘要： In an internal combustion engine, the fuel is conveyed by an electrically driven fuel pump. The intake side of this pump is connected to a fuel tank and its outlet side is connected to a pressure region. A prerun of the electrically driven fuel pump may be performed before the startup of the internal combustion engine. In order to increase the service life of the fuel pump, an actual pressure (pactual) in the pressure region may be detected by a pressure sensor and the execution of the prerun be a function of at least the signal of the pressure sensor.

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.
