Definitions

  • the present invention relates to a fuel tank for a vehicle, in particular for underfloor arrangement in a rail vehicle, comprising a first fuel compartment and an fuel outlet device for drawing fuel from said fuel tank.
  • the present invention is based on the technical teaching that enhanced usage of the volume of fuel available within the tank may be achieved by providing a fuel tank comprising a first fuel compartment and a fuel outlet device for drawing fuel from said fuel tank.
  • a second fuel compartment being spatially associated to said first fuel compartment and having a smaller volume than said first fuel compartment and a first fuel supply arrangement for supplying fuel from said first compartment to said second compartment.
  • Said fuel outlet device is then located within said second fuel compartment.
  • the first fuel supply arrangement allows for supplying fuel from said first fuel compartment to said second fuel compartment at periods where no adverse inclination or motion situation is prevailing during operation of the vehicle.
  • the fuel level within the second fuel compartment may be at least maintained at a certain value.
  • said fuel level within the second fuel compartment is even raised during such periods.
  • this is due to the fact that, with such an arrangement, even at low fuel levels within said first fuel compartment, a certain fuel level within said second fuel compartment may be at least maintained, said fuel level being higher than the one in the first compartment and, thus, assuring continuous fuel supply via said outlet device even at low fuel volumes remaining within the tank.
  • the fuel within the second compartment will, as well, tend to accumulate at a location remote from the fuel outlet device, the smaller volume of the second fuel compartment leads to a shorter distance of this location of accumulation from the fuel outlet device.
  • the fuel level in the region of the fuel outlet device will not drop as far as it would be the case in a known single compartment tank. Consequently, continuous fuel supply from the tank will be guaranteed up to smaller fuel volumes remaining within the tank. This leads either to an elevated action radius of the vehicle at a given tank volume or to a reduced necessary tank volume at a given action radius of the vehicle.
  • the second fuel compartment may be located anywhere immediately adjacent to the first fuel compartment. Preferably, said second fuel compartment is located within said first fuel compartment. This allows for a very simple and cost effective design of the fuel compartments, in particular of the second fuel compartment.
  • the second fuel compartment may be defined by one or more simple wall elements arranged within the first fuel compartment.
  • the second fuel compartment - apart from the connection via the first fuel supply arrangement - may be completely sealed versus the first fuel compartment.
  • the second fuel compartment comprises a first aperture located in an upper region of said second fuel compartment, said second fuel compartment being open towards said first fuel compartment via said first aperture.
  • said first aperture is located at a first level which is lower than a predetermined first fuel level within said first fuel compartment.
  • said first fuel level is located below the maximum filling level of the fuel tank.
  • the second fuel compartment may be designed in any suitable shape. It may, for example, have a substantially rectangular cross section in a horizontal plane. Preferably, it has a substantially elliptic cross section in a horizontal plane.
  • Such a design in combination with an fuel outlet device located in the region of the center of the elliptic second fuel compartment leads to an optimized use of the fuel volume within the tank. This is due to the fact that such a design, thanks to the continuously reducing width of the compartment with increasing distance to the center of the compartment, even at elevated inclination angles of the tank leads to sufficiently high fuel levels reaching to the fuel outlet device for ensuring fuel supply from the fuel tank.
  • the long main axis of the elliptic cross section runs substantially parallel to the axis about which the most important, i.e. the most interfering inclinations of the tank are to be expected during operation of the vehicle.
  • these are usually the inclinations causing a nodding movement about a horizontal axis transverse to the longitudinal axis of the vehicle.
  • the cross section in a horizontal plane may be substantially circular as a special case of the elliptic design.
  • the second compartment may be achieved in any suitable manner.
  • it may be a completely separate module.
  • the first fuel compartment and the second fuel compartment share at least one component.
  • said first fuel compartment is defined by a plurality of first wall elements and said second fuel compartment is defined by at least one second wall element and at least one of said first wall elements.
  • the components of the second fuel compartment may be arranged in any suitable manner.
  • said second wall element is arranged, in any suitable geometry, circumferentially with respect to said fuel outlet device and mounted to a first wall element forming a bottom wall of said first fuel compartment.
  • said second wall element preferably does not reach to a first wall element forming an upper wall of said first fuel compartment.
  • said second wall element partly, e.g. in at least one connection region, reaches up and is connected to said first wall element forming an upper wall of said first fuel compartment.
  • said first fuel supply arrangement is adapted to provide a first fuel stream towards said second compartment, wherein said first fuel stream is at least equal to a second fuel stream drawn from said second compartment during operation of said vehicle.
  • said second fuel stream is selected to be equal to a maximum fuel stream drawn from said second compartment during operation of said vehicle - with continuous fuel supply to said second fuel compartment - a rise in the fuel level within the second fuel compartment will result during periods where less than said maximum fuel stream is drawn from said second fuel compartment.
  • said first fuel stream is selected to exceed said maximum fuel stream drawn from said second compartment during operation of said vehicle.
  • said first fuel stream is selected to exceed said maximum fuel stream drawn from said second compartment during operation of said vehicle.
  • the first fuel supply arrangement may be designed in any suitable manner to feed fuel to the second fuel compartment.
  • said first fuel supply arrangement comprises a first fuel pump.
  • said first fuel supply arrangement comprises a first fuel filter.
  • the second fuel compartment contains fuel that is at least pre-filtered to some extent. This reduces further fuel filtering effort prior to feeding the fuel to a motor.
  • the first fuel compartment may be of any suitable design and partition. It may comprise one single hollow space. With further embodiments of the present invention, said first fuel compartment comprises a plurality of sub-compartments, wherein for at least a part of said sub-compartments a separate first fuel supply arrangement is provided for supplying fuel from said sub-compartment to said second fuel compartment. Said separate first fuel supply arrangements may be arranged in series or in parallel.
  • Advantageous embodiments of the fuel tank according to the present invention comprise a first fuel level sensor, said first fuel level sensor being arranged for providing a low fuel signal when a fuel level within said second fuel compartment falls below a predetermined second fuel level.
  • a first fuel level sensor it is possible to interrupt fuel supply to a motor. This prevents intake of air into the fuel stream supplied to the motor which otherwise might cause serious motor damage.
  • said fuel outlet device comprises first fuel supply interrupt means for interrupting fuel supply from said second fuel compartment via said fuel outlet device. Said first fuel supply interrupt means is then connected to said first fuel level sensor and adapted to interrupt fuel supply via said fuel outlet device upon receipt of said low fuel signal.
  • Such first fuel supply interrupt means may, for example, be a fuel valve or the like responding to said low fuel signal.
  • said fuel outlet device comprises a second fuel pump for drawing fuel from said second fuel compartment. Said second fuel pump is then connected to said first fuel level sensor and arranged for stopping operation upon receipt of said low fuel signal.
  • the fuel tank according to the present invention comprise a second fuel level sensor, said second fuel level sensor being arranged for providing a high fuel signal when a fuel level within said second fuel compartment reaches a predetermined third fuel level.
  • said first fuel supply arrangement comprises second fuel supply interrupt means for interrupting fuel supply to said second fuel compartment via said first fuel supply arrangement.
  • Said second fuel supply interrupt means is then connected to said second fuel level sensor and adapted to interrupt fuel supply via said first fuel supply arrangement upon receipt of said high fuel signal.
  • such second fuel supply interrupt means may, for example, be a fuel valve or the like responding to said high fuel signal.
  • said first fuel supply arrangement comprises a first fuel pump for pumping fuel to said second fuel compartment. Said first fuel pump is then connected to said second fuel level sensor and arranged for stopping operation upon receipt of said high fuel signal.
  • preferred embodiments of the fuel tank according to the present invention comprise a fuel return device for returning fuel from a motor to said second fuel compartment.
  • Venting of the first and second fuel compartment may be provided in any suitable way, e.g. by separate venting lines or the like.
  • one single venting device is provided for both fuel compartments.
  • said second fuel compartment is preferably open, at an upper side, towards said first fuel compartment. Then, preferably, said first fuel compartment and said second fuel compartment share a common venting device.
  • the present invention also relates to a vehicle, in particular a rail vehicle, comprising a transport compartment with a floor and a fuel tank according to the present invention arranged below said floor.
  • a vehicle in particular a rail vehicle, comprising a transport compartment with a floor and a fuel tank according to the present invention arranged below said floor.
  • Figure 1 is a schematic sectional representation of the rail vehicle 1 which comprises a transport compartment 1.1 for transporting passengers.
  • the transport compartment 1.1 has a floor 1.2.
  • the fuel tank 2 is arranged under a low floor section of the floor 1.2. From the fuel tank 2 fuel is supplied to a diesel motor 3 driving, via a gearing unit 4, a wheel set 5 of the vehicle 1.

  • This second wall element 2.21 does not reach up to the first wall element 2.12 forming the upper wall of the tank 2.
  • the second fuel compartment 2.2 is open towards the first fuel compartment 2.1 in an upper region via a first aperture 2.22. Since the second fuel compartment 2.2 has no upper wall, said first aperture 2.22 is formed by the second fuel compartment 2.2 simply being open at its upper side.
  • the first aperture may be achieved by any other suitable means. For example, a hole may be formed in a wall delimiting said second fuel compartment or the like.
  • the first aperture 2.22 is located at a first level above the bottom wall 2.11 of the tank 2.
  • the first level is determined by the height of the upper edge of the second wall element 2.21. This height of the upper edge of the second wall element 2.21, i.e. the first level, is chosen to be inferior to the maximum fuel level reached when filling the tank 2 completely. This maximum fuel level is indicated by the dashed contour 6 in Figure 2.
  • the first aperture 2.22 assures that, both, the first fuel compartment 2.1 and the second fuel compartment 2.2 are filled with fuel.
  • the filling device e.g. a simple filling line, may be located at any position within the tank 2. In other words, this design advantageously does not impose any constraints with respect to the location of the filling device.

  • apertures may be of any shape. For example, they may be substantially u-shaped.
  • due to the connection between the second wall element 2.21 and the upper wall 2.12 of the first fuel compartment 2.1 enhanced rigidity and stability of the fuel tank 2 is obtained.

  • the second fuel supply arrangement 2.4 further comprises a first fuel level sensor 2.46 located slightly above the level of the fuel inlet 2.45 of the third fuel line 2.41.
  • This first fuel level sensor 2.46 is adapted to provide a first fuel level signal, namely a low fuel signal, at times when it is not immersed in fuel, i.e. when the fuel within the second fuel compartment has reached a given second fuel level.
  • This low fuel signal is forwarded to the second fuel pump 2.43 via a first signal line 2.47.
  • the second fuel pump 2.43 in response to said low fuel signal, stops operation in order to avoid intake of air into the fuel injection system of the motor 3 which otherwise might cause serious motor damage. If, due to immersion of the first fuel level sensor 2.46, there is no low fuel signal present at signal line 2.47, the second fuel pump 2.43 is adapted to operate, provided that it is not switched off by other means.
  • the first fuel pump 2.33 may run permanently to continuously supply fuel from the first fuel compartment 2.1 to the second fuel compartment 2.2. Excess fuel supplied to the second fuel compartment 2.2 will then return to the first fuel compartment via the first aperture 2.22.

  • the first fuel supply arrangement 2.3 sucks in air and, consequently, fuel supply to the second fuel compartment 2.2 is interrupted.
  • this continued fuel supply to the motor 3 will also be maintained over an extended period of time with interrupted fuel supply to the second fuel compartment 2.2. Even in such a situation, due to the smaller size of the second fuel compartment 2.2, continued fuel supply to the motor 3 will be maintained until the fuel level within the second fuel compartment 2.2 has dropped down to an inclined fuel level as it is indicated in Figure 2 by the dashed contour 11.

This venting line 2.6 is located close to the center of the second compartment 2.2'.
  • the first fuel supply arrangements 2.3' may be operated in any suitable way. For example, they may all be operated at a time to continuously supply fuel to the second fuel compartment. However, it may also be provided that the first fuel supply arrangements 2.3' are operated sequentially, e.g. when fuel supply is interrupted from one sub-compartment 2.18' it is switched to the next sub-compartment 2.18' and so on.
