Definitions

  • the present invention relates to a tank for a reducing agent.
  • the tank has a planar first tank volume and at least one elongate second tank volume.
  • the invention also relates to a motor vehicle having a tank for a reducing agent and to a method for operating an SCR system of a motor vehicle having at least two tank volumes for a reducing agent.
  • SCR systems which can be retrofitted in particular are of great significance, because the purchase costs of off-road vehicles are generally very high.
  • the system components of such an SCR system should be constructed to be very light with regard to their weight, and should have a low level of complexity with regard to freedom from maintenance. Furthermore, the production and operating costs must be reduced and, in particular, the least possible amount of additional energy of the internal combustion engine or of the electrical energy accumulator or energy generator should be consumed. In the case of a retroactive installation of such an SCR system into a motor vehicle, the modification measures required should also be as minor as possible.
  • a tank for a reducing agent in which the tank permits retroactive installation into a motor vehicle.
  • a motor vehicle which at least partially solves the problems highlighted in the introduction and in particular specifies the configuration of a tank for a reducing agent, in which the configuration does not restrict the user with regard to the visibility of the body of the vehicle.
  • it is intended to specify a method for operating an SCR system of a motor vehicle in which the method permits simple operation of the SCR system and therefore permits considerable advantages with regard to servicing, production, operating costs and energy consumed.
  • a tank for a reducing agent forming ammonia or including ammonia comprises a planar first tank volume having a first height, a first mean base area and a first ratio of the first mean base area to the first height of greater than 500 cm, in particular 1,000 cm or even greater than 1,500 cm.
  • At least one elongate second tank volume has a second height and a second mean base area. The at least one elongate second tank volume projects, protrudes or overhangs relative to the planar first tank volume.
  • a tank of this type it is, of course, possible to use a tank of this type to store a reducing agent which already includes ammonia and/or an ammonia precursor.
  • an aqueous urea solution is preferable as a reducing agent.
  • the aqueous urea solution is, for example, available under the trademark AdBlue.
  • AdBlue AdBlue
  • the solution is injected, sprayed or vaporized into the exhaust line upstream of an SCR catalytic converter, for example through the use of a dosing pump or an injector.
  • Ammonia (NH 3 ) and water are generated from the aqueous urea solution in a hydrolysis reaction by using a catalyst (for example which is still outside of the exhaust gas) and/or as a result of contact with the hot exhaust gas.
  • the ammonia which is generated in this way may react, in an SCR catalytic converter at a corresponding temperature, with the nitrogen oxides of the exhaust gas.
  • aqueous urea solution is approximately 1% to 8% of the fuel (diesel fuel) which is used, depending on the untreated emissions of the internal combustion engine. It is therefore necessary precisely in this case for a correspondingly large tank volume to be carried on board.
  • the tank is shaped in such a way that a first tank volume has a planar construction, that is to say simultaneously has a comparatively large length and/or width, while having a small height.
  • the first mean base area of the first tank volume is generated by averaging the tank cross-sectional area over the first height (that is to say perpendicularly thereto).
  • the first height is preferably also the greatest height of the first tank volume, which is preferably for example a maximum of 10 cm or even only a maximum of 5 cm.
  • the elongate second tank volume forms a direct continuation of the first tank volume, and is in particular non-detachably connected to the first tank volume.
  • the second tank volume has, along its elongate extent, a second height which is comparatively large in relation to the length and width of the second tank volume.
  • the second mean base area is generated, similarly to the first tank volume, by averaging the tank cross-sectional area of the second tank volume over the second height.
  • the second height is preferably the averaged or even the smallest height of the second tank volume, which is preferably for example at least 20 cm or even at least 50 cm.
  • the second tank volume is in particular formed relative to the first tank volume in such a way that the first height and the second height, and accordingly also the first and second mean base areas, extend in each case in virtually the same direction (parallel).
  • the first base area is preferably at least 0.5 m or even at least 1m 2 .
  • the tank is preferably constructed in such a way that a second ratio of the second mean base area and the second height is smaller than 2 cm, in particular smaller than 1.5 cm.
  • the ratio of the second height (H 2 ) to the first height (H 1 ) is greater than 3:1, that is to say
  • the ratio may even be at least 5:1.
  • the at least one second tank volume is disposed directly in an edge region of the first tank volume, and in particular in a corner region of the first tank volume.
  • the tank may also have further second tank volumes which are advantageously likewise disposed in the edge region of the first tank volume, particularly advantageously in the further corner regions of the first tank volume.
  • the first tank volume for holding the reducing agent preferably has a first volume of at least 90 l (liters) and the at least one elongate second tank volume preferably has a second volume which encompasses at most 10% of the first volume, and in particular at most 5%.
  • the respective volume of the second tank volumes should in particular be adapted to the number of second tank volumes, that is to say in the case of two second tank volumes being provided, the respective second volumes are at most 5% of the first volume, and in the case of three second tank volumes being provided, the respective second volumes are in each case 3.3% of the first volume.
  • the plurality of second tank volumes are directly connected to one another through the use of a collecting line, in such a way that the liquids which are contained in the second tank volumes can be exchanged with one another.
  • the collecting lines are in particular connected to that end of the second tank volume which is disposed so as to face away from the first tank volume.
  • a third tank volume is connected through a connecting line to the first tank volume and/or to the at least one second tank volume.
  • the third tank volume should be matched in terms of its shape to the spatial conditions in the vehicle.
  • the volume of the third tank volume however corresponds in particular to that of the at least one second tank volume, that is to say encompasses for example at most 10% of the first volume.
  • the third tank volume is significantly smaller than the at least one second tank volume.
  • the third tank volume thus has a third volume which corresponds in particular to at most 1% of the first volume.
  • the at least one second tank volume and/or the third tank volume of the tank preferably includes a heater.
  • the heater is in particular an electrical heater, which can for example be connected to electrical accumulators or electrical generators of a motor vehicle.
  • the heating power can in particular be automatically activated on demand and/or regulated and should be configured with regard to a maximum heating power such that a frozen reducing agent with a volume of a minimum of 0.5 l (liters) is liquefied within 10 minutes.
  • At least the first tank volume has a housing composed of plastic.
  • High-grade steel or plastic tanks are particularly suitable for reducing agents, in particular for an aqueous urea solution.
  • plastic is preferable since it has a lower weight than a construction using high-grade steel and has a certain expansion capability. It is very particularly preferable in this case to use polyurethane as a material, for example a high-pressure-resistant polyurethane.
  • At least the first tank volume of the tank has heat insulation. The heat insulation is in particular constructed so as to encompass only a partial region of the first tank volume.
  • a motor vehicle comprising an internal combustion engine, an exhaust system having an SCR catalytic converter and a reducing agent metering device, a body with a roof, and a tank, in particular a tank according to the invention, disposed on the roof and having a planar first tank volume for a reducing agent.
  • the reducing agent metering device includes, for example, an injector or an injection nozzle and a dosing pump which supplies the reducing agent from a tank volume to the exhaust system.
  • the body of the motor vehicle includes all of the structural parts of the motor vehicle and a roof which is disposed above a driver's cab.
  • the planar first tank volume is disposed on the roof, in particular in such a way that a driver or user (that is to say any other persons present in the driver's cab) of the vehicle is not restricted in terms of their freedom of movement by the first tank volume.
  • the first tank volume may be disposed above the roof, below the roof or else within the roof.
  • the first tank volume may have cutouts or other profiles which are adapted firstly to the construction of the roof and/or to the freedom of movement of the driver or user.
  • the tank preferably extends over virtually the entire area of the roof and therefore, through the use of the largest possible base area and the smallest possible height, utilizes the greatest possible first tank volume.
  • any other desired shape of the first tank volume equally falls within the scope of this construction of the vehicle according to the invention in this case.
  • the tank of the motor vehicle preferably has a planar first tank volume and at least one elongate second tank volume.
  • the at least one elongate second tank volume is formed so as to project, protrude or overhang in relation to the planar first tank volume and the at least one second tank volume is disposed along a roof beam of the body.
  • the first tank volume is thus distinguished in particular in that the greatest possible length and width of the tank are provided so as to utilize the roof area, and the smallest possible first height is provided in such a way that, as far as possible, the user or the driver is not restricted.
  • the at least one elongate second tank volume has the smallest possible width and length, but has a large height along the elongate extent of the second tank volume, in such a way that the at least one second tank volume can run along a roof beam of the body.
  • the second tank volume should be disposed geodetically (with regard to its height position) below the first tank volume.
  • first tank volume and/or the second tank volume may be an integral part of the body and/or of a driver's cab. This applies in particular to applications in which the tank is already installed during the production of the motor vehicle.
  • integral means in particular that the first tank volume and/or the second tank volume can be removed with (partial) deformation and/or destruction of the body.
  • a third tank volume is connected through a connecting line to at least one second tank volume or to the first tank volume, and at least the first tank volume is connected through the third tank volume to a reducing agent metering device.
  • a second tank volume therefore need not necessarily be provided in this case.
  • the third tank volume is thus supplied with the reducing agent directly from the first tank volume.
  • the third tank volume is disposed in particular outside the driver's cab, in the vicinity of the dosing pump or of an injector of the reducing agent metering device.
  • the third tank volume is in particular disposed in such a way that the waste heat of the engine or the exhaust line can be utilized as heating power for the third tank volume.
  • the third tank volume is in particular at least partially heat-insulated with respect to the environment, in such a way that freezing of the reducing agent is prevented, or thawing of the reducing agent is accelerated.
  • the third tank volume is preferably disposed geodetically below the at least one second tank volume and may, in the case of a plurality of second tank volumes, be connected to each of the plurality or preferably to a collecting line which connects the plurality of second tank volumes.
  • the collecting line is preferably connected to those ends of the second tank volumes which face away from the first tank volume.
  • the third tank volume is in particular disposed outside a driver's cab of the motor vehicle, in particular in the direct vicinity of a delivery pump of the SCR system for the reducing agent. If a third tank volume is not provided, the at least one second tank volume is connected through a connecting line (which, if appropriate, is flexible, for example formed by a hose) to a reducing agent metering device.
  • the connecting line may also be connected to a collecting line of the plurality of second tank volumes, as already described above.
  • a reducing agent metering device is connected to at least one second tank volume which can be filled under gravitational force, or to a third tank volume which can be filled under gravitational force.
  • the reducing agent metering device includes, for example, at least one pump and an injection configuration or an injector and is supplied with the reducing agent from the at least one second tank volume or from the third tank volume.
  • the at least one second tank volume is filled with reducing agent from the first tank volume as a result of gravitational force.
  • the third tank volume is filled with reducing agent either from the first tank volume and/or from the at least one second tank volume.
  • Such a configuration of the tank volumes makes it possible to dispense with additional supply pumps, and also to prevent insufficient filling of a tank volume as a result of the motor vehicle traveling long distances in (oblique) awkward positions.
  • This is obtained in particular by providing a further second tank volume or the third tank volume, wherein the second tank volumes can additionally be connected to one another through the use of a collecting line for the equalization of the second tank volumes.
  • a roof region of the motor vehicle has heat insulation, such that at least the first tank volume of the tank is at least partially insulated with respect to the external environment by the heat insulation.
  • the (in particular non-metallic) heat insulation serves in particular to protect the first tank volume from climatic influences of the environment, such that freezing of the reducing agent within the first tank volume is prevented as far as possible, but at the same time a liquefaction of the reducing agent can be accelerated as a result of the first tank volume not being heat-insulated with respect to the interior space of the cabin of the motor vehicle.
  • a method for operating an SCR system of a motor vehicle having at least two tank volumes, a reducing agent metering device and an SCR catalytic converter comprises storing a reducing agent for the SCR system in one of the tank volumes,
  • the method is proposed in particular for operating a motor vehicle according to the invention, and the motor vehicle has in particular a tank according to the invention.
  • the reducing agent metering device includes for example an injector or a delivery pump and an injection nozzle for dispensing the reducing agent into the exhaust line.
  • the method is distinguished in that, during the operation of the motor vehicle, the reducing agent is delivered from a first tank volume into at least one further tank volume as a result of gravitational force, in such a way that the at least one further tank volume forms an in particular permanently-filled reservoir for the reducing agent metering device.
  • a reservoir therefore refers to a volume which is permanently filled in particular in awkward positions of the vehicle and when the further tank volumes which are provided are partially filled, and which can be emptied through the reducing agent metering device only once the further tank volumes have emptied.
