    摘要： A fuel supply system (2) for an internal combustion engine (1) for, in particular, a motor vehicle. The fuel supply system (2) is used for delivering fuel from a fuel tank (3) into at least one intake manifold (4) or at least one combustion chamber (5) of the internal combustion engine (1) and includes at least two fuel pumps (6, 8; 11) connected in series. In order to ensure that the internal combustion engine (1) is supplied with fuel at any operating point of the internal combustion engine (1), it is provided that at least two of the fuel pumps (6, 8; 11) of the fuel supply system (2) take the form of electric fuel pumps (6, 8). The second electric fuel pump (8) in the direction of flow is preferably adjusted to a separate, variable pressure level in a demand-responsive manner, so that the pressure and fuel quantity are controlled.

    摘要： Method for operating a fuel supply system of an internal combustion engine, especially of a motor vehicle, wherein fuel is pumped into a storage space (17) with the aid of a pump (12, 16) and a pressure is generated in the storage space (17). In the system, an actual value of the pressure is measured with the aid of a pressure sensor (21) and the pressure in the storage space (17) is controlled (open loop and/or closed loop) to a desired value. A fault in the fuel supply system (10) is detected via a plausibility control. When a fault in the fuel supply system (10) is detected, a diagnostic cycle of the internal combustion engine is initiated. Diagnostic functions are activated which check individual components (18, 19, 21) of the fuel supply system (10) as to operability.

    摘要： In an internal combustion engine, a real fuel quantity (rk_w), supplied from a high-pressure region of a fuel system into a combustion chamber of the engine, depends on a real rotational moment. In addition, the control duration (dwmsvo) of a volume control valve, with which the fuel supplied from a fuel pump into the high-pressure region can be affected, depends on the difference between a real pressure and a determined pressure (prist) in the high-pressure region. The supply output of the fuel pump, which supplies into the high-pressure region, depends in turn on the rotational speed (nmot) of a crankshaft of the engine. In order to avoid problems relating to too much or too little fuel being injected into the combustion chamber of the engine, it is proposed that a real control duration (dwmsvo) of the volume control valve, the determined rotational speed (nmot) of the crankshaft of the engine, and the determined pressure (prist) in the high-pressure region determine a test fuel quantity (rk_um) and that this test fuel quantity is compared with a real fuel quantity (rk_w_determined from the real rotational moment.
