In addition, the risk of damage to an im State of the art arranged on the motor vehicle underbody Finned cooler or the like.
  • the fuel is a diesel fuel.
  • the fuel supply system of the present invention discussed above works particularly well with diesel fuels heating problems occurring outstanding and at the same time cost-effective to control. Nevertheless this is not exclusively on diesel fuels limited, but can also apply to everyone else Fuel systems find application where one Heating of the fuel, for example, due to the Use of high pressure pumps can be determined.
  • the injection system is a common rail injection system. On this way can take advantage of the present invention to the most modern variant of diesel fuel engines be transmitted.
  • the opening into two parts of the returned, heated fuel flow compared to the Venturi nozzle in the rear wall or in the housing of the suction jet pump is arranged.
  • This offers the advantage of one particularly compact design of the suction jet pump according to the invention. It is also ensured that the im Fuel sump at a point as low as possible Suction jet pump arranged with fuel tanks is relatively safe from running dry, at the same time over has the opening for dividing the volume flow, so that the branched volume flow in turn in the area of a the lowest possible point in the fuel tank can be returned. It also starts from there a good swirling and mixing of the whole Fuel tank content achievable.

So that the volume flow of the heated in the fuel tank Fuel in the most suitable place in the Fuel tank are guided so that the desired optimal Mixing and swirling of the heated returned fuel and cool in the fuel tank fuel under consideration the special geometrical conditions of each Tank variant can be selected.
  • the suction jet pump be pressure controlled is. This in turn can quickly turn to the applicable boundary conditions of the respective operating state Be taken into account and by the Suction jet pump amount of fuel supplied to the fuel reservoir adapted to or corresponding to the corresponding need can be set. It also prevents the partial flow of recirculated fuel that should flow through the Venturi nozzle, whose throughput exceeds and to a defect of the suction jet pump or too could cause malfunction.
  • a suction jet pump in particular for a fuel supply system discussed above proposed with a suction jet pump inlet downstream Venturi nozzle, one in the direction of flow suction jet pump opening downstream of the Venturi nozzle, a further subordinate catch nozzle, which in a suction jet pump outlet opens, the suction jet pump inlet a connection for a fuel return section and the suction jet pump outlet either opens into the fuel reservoir or a connection for a fuel transfer line section.
  • the Suction jet pump according to the invention provided that the Opening for volume flow distribution opposite the Venturi nozzle is arranged in the rear wall of the suction jet pump. Furthermore, it is provided that the cross section of the Opening variable or with constant opening cross-section a valve is arranged downstream of the opening, so that a variation of the volume of the recycled into the fuel tank Partial current is possible. Furthermore is provided that the variable opening or the valve a control unit is assigned to regulate the volume flow. Last but not least, it is provided that the fuel return line from the arranged in front of the suction jet pump Opening out into the fuel tank is extended. Finally, it is envisaged that the Suction jet pump is pressure controlled. With that, too already above on the fuel supply system according to the invention discussed benefits in synergistic Way achieved.
  • the suction jet pump according to the invention is proposed that to form the opening for the volume flow division a small one in the back wall of the suction jet pump Hole is drilled.
  • the hole forming the opening in the The rear wall is at the same height and central to rearward extension of the axis of symmetry of the suction jet pump or the Venturi nozzle.
  • the opening or that Hole is preferably 1.5 mm in diameter. This corresponds to the diameter in the present embodiment the Venturi nozzle and thus leads to a division of the return flow into two partial flows of approx. 50 each %.
  • the degree of division depends on the most diverse Requirements or factors. Determining factors are, for example, the consumption of the motor vehicle engine, the total amount of fuel to be pumped, the minimum and maximum throughput of the high pressure pump as well the cooling or temperature requirement etc.
  • the distribution of the recirculated, heated fuel volume flow in two partial flows means that half of the Return flow remains in the suction jet pump and to Intake of fresh, cool fuel from the fuel tank can be used so that this fresh Fuel along with the proportionate heated recirculated Fuel supplied to the fuel reservoir can be. The other part of the returned fuel is delivered directly to the tank. In this way the proportion of fresher and cooler fuel increases at the to be pumped into the fuel reservoir Amount of fuel, so that the desired temperature limits are easily compliant.
  • the ratio of the mixing can not only statically using a hole, but also flexibly adjusted by a regulated or controllable valve become.
  • a regulated or controllable valve For. B. targeted for different Load conditions of the motor vehicle engine or the motor vehicle high pressure pump different mixing ratios can be set, creating a defined Temperature band, if not a constant temperature level, can be regulated, which subsequently the Temperature load of the high pressure pump significantly reduced or with appropriate temperature control in the for High pressure pump optimizes the optimal temperature range, and resulting in less wear and tear and thus lower fuel consumption can be achieved become.
  • Another advantageous aspect of the invention is that optimized by the above Position of the hole a particularly intensive mixing of the fuel emerging from the opening the remaining fuel tank content can be done. This is related among other things to the fact that the so positioned Always open below the normal fuel level is in the tank. Furthermore, the branched off through the opening Partial flow mainly due to the aligned position of the Opening relative to the venturi opening with a relative high pressure, which is a reaction the accelerated flow rate of the fuel through the venturi opening. hereby the branched partial flow flows with a comparatively high speed in the in the fuel tank yet fresh fuel. This causes an extreme Swirling of the heated recirculated fuel in the fuel tank and thereby intensifies the Mixing, so disproportionate local heating be avoided.
  • the present invention leads among other things as a result of the replacement of comparatively extremely expensive components and a considerable Simplification of the fuel supply system, which at Savings in large series not to be underestimated multi-digit range.
