    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： A fuel injection system is proposed which brings about an improvement in the acceleration behavior of an internal combustion engine. The fuel injection system includes metering valves actuatable by means of an air flow measuring device, at which valves a pressure difference can be held constant via control valves and the pressure difference is variable in accordance with operational characteristics of the engine. To this end, the control valves are located on a control pressure line in which a control throttle and an electromagnetic valve are disposed. At the same time, pressure limitation elements communicate with the control pressure line and, in the event of acceleration of the engine, reduce the extent of increase of control pressure and thus assure fuel metering corresponding with the operational state of the engine.

    摘要： A regulating apparatus is proposed for a fuel supply system for a mixture-compressing, externally ignited internal combustion engine, which serves to enrich the fuel-air mixture furnished to the engine when it is started cold and while it warms up. The regulating apparatus comprises a pressure-regulating valve which sets the fuel pressure, the closing force of which on the movable valve part is influenced by a temperature-dependent element by means of a relay device and a regulating spring coaxially correlated therewith. Accordingly in a predetermined temperature range, the temperature-dependent element and the movable valve part are connected only by the regulating spring.

    摘要： Known tank flanges have a main filter which has a filter housing with an inlet and an outlet, and a first connecting duct for connecting the main filter to a feed unit. The filter housing is integrated in the tank flange, and filter fabric is inserted into the filter housing and the filter housing is closed off by a filter cover. The inlet of the filter housing is connected to the pressure side of a feed unit and the outlet leads to an internal combustion engine. A disadvantage is that, in order to exchange the filter fabric, the large-area filter cover must be opened, as a result of which a large amount of fuel vapor is dissipated to the atmosphere. In the case of the tank flange according to the invention, the exchangeability of the main filter is simplified by virtue of the main filter being embodied as a filter cartridge. It is provided according to the invention that the inlet of the main filter extends into the first connecting duct of the tank flange and therein forms a sealed connection.
