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： A method for operating an internal combustion engine, e.g., of a motor vehicle, where fuel is supplied under pressure via at least one injection valve. The injected fuel quantity is influenced by the injection time of injection valve. In order to be able to provide optimum operating comfort and good component reliability even in the event of an incorrect fuel pressure, a maximum allowable torque of the internal combustion engine that is dependent on the instantaneous fuel pressure is determined.

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： An internal combustion engine is operated according to a method, in which the fuel is pumped from a first fuel pump to a second fuel pump and from there into a high-pressure region. The fuel passes therefrom into at least one combustion chamber of the internal combustion engine, by means of at least one fuel injection device. In certain operating conditions of the internal combustion engine, the pressure in the high-pressure region is lowered by means of a release device. According to the invention, the reliability and security of operating the internal combustion engine may be increased by monitoring the functioning of the release device (58 through 68).

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).
