Definitions

  • the invention relates to a tank for storing a fuel for a motor vehicle.
  • a fuel for a motor vehicle typically requires several liquid supplies that can freeze at low temperatures in their tanks.
  • Such fuels are, for example, the fuel for operating an internal combustion engine, windscreen wiper water for cleaning the windows of the motor vehicle, coolant for operating the internal combustion engine or reducing agent for reducing harmful components in the exhaust gas of an internal combustion engine.
  • the use of reducing agent for purifying exhaust gases of an internal combustion engine has recently gained considerable importance in the automotive sector.
  • a frequently used process for exhaust gas purification, for which a reducing agent is required as an additional fuel of the motor vehicle, is the selective catalytic reduction (SCR) process.
  • SCR selective catalytic reduction
  • a reduction agent is supplied to the exhaust gas of the internal combustion engine, with which nitrogen oxide compounds (NOx) in the exhaust gas are effectively reduced within the exhaust system.
  • the method of selective catalytic reduction is used in particular in exhaust systems of lean-burn internal combustion engines, such as diesel engines. These have an increased output of nitrogen oxide compounds.
  • ammonia is used as the reducing agent.
  • Ammonia is regularly not stored in the motor vehicle itself, but in the form of a so-called reducing agent precursor, ie a substance that is still (chemically) converted into ammonia (as needed).
  • a frequently used reducing agent precursor is urea - Water solution.
  • a 32.5% urea-water solution is available for this purpose under the trade name AdBlue and is widely used.
  • AdBlue urea-water solution
  • AdBlue urea-water solution
  • a tank for a reducing agent must therefore be designed such that it is not damaged when the reducing agent stored in the tank freezes.
  • a particularly cost-effective and particularly easy to install tank for a fuel for a motor vehicle with an effective Schuvor- direction and a particularly advantageous method for energetically favorable positioning of a heater can be specified in a tank.
  • the invention therefore relates to a tank for storing a liquid fuel for a motor vehicle, comprising a tank wall and an interior, which is bounded by the tank wall, and at least one heater, which is mounted from the outside through the tank wall and extends into the interior.
  • the tank preferably has a tank wall made of plastic, wherein the tank in particular forms an enclosing (one-piece) tank wall.
  • the operating fluid (under normal operating conditions or room temperature) can now be permanently stored in the interior of the tank.
  • the liquid fuel is preferably a reducing agent or a reducing agent precursor for reducing pollutant components in the exhaust gas of an internal combustion engine.
  • the fuel may be a urea-water solution.
  • the tank wall preferably has a corresponding (second) mounting opening, through which the at least one heating device is mounted.
  • a delivery device for the liquid operating material may also be provided in the tank.
  • the conveying device can be provided, for example, in a metallic housing on the tank wall, which is positioned in a (only) provided (separate or first) mounting opening of the tank.
  • PTC positive temperature coefficient
  • this may also be designed in the manner of a liquid heater, in which a hot fluid flows through a heating loop.
  • a heating fluid for example, the cooling water of the internal combustion engine of a motor vehicle can be used.
  • the at least one heating device may comprise a so-called heat pipe (“heat pipe”)
  • Heat pipes generally contain a hermetically encapsulated volume, usually in the form of a tube, which is filled with a working medium (eg water). It fills the volume to a small extent in the liquid state, and to a large extent in the vapor state, each containing a heat transfer surface for a heat source (near the tank wall or outside the tank wall) and a heat sink (inside the tank or opposite the heat source)
  • a heat transfer surface for a heat source near the tank wall or outside the tank wall
  • a heat sink inside the tank or opposite the heat source
  • the working medium begins to evaporate, causing the pressure in the vapor space to increase locally above the liquid level, resulting in a small pressure gradient within the heat pipe, so that the resulting vapor flows in the direction of the heat sink where it will flow
  • the previously recorded latent heat is released again.
  • this at least one heating device is a local, retrofitted, heat source positioned at a predetermined point through the tank wall for the targeted and effective thawing of frozen fuel in the tank interior.
  • the heating power is deliberately introduced far into the interior of the tank by means of the at least one heating device.
  • a plurality of such heating devices may be provided, so that a predetermined distribution of the heaters is reached deep into the interior.
  • the heating devices can also be designed differently, in particular with regard to their nature, length, orientation, heating power, etc.
  • This embodiment of the tank in particular allows retrofitting with demand-driven, efficient heating devices.
  • the tank is particularly advantageous if the at least one heating device is designed with at least one of the following configurations:
  • the at least one heater has a cross-sectional shape and a length perpendicular to the cross-sectional shape. The cross-sectional shape substantially corresponds to the shape of the second mounting opening, through which the at least one heating device can be mounted.
  • the device according to the invention is advantageous if the at least one heating device is detachably and fluid-tightly connected to the tank wall. It is particularly advantageous to introduce the heater through the second mounting hole in the tank, or to mount in the tank when the second mounting hole is located in the bottom of the tank in the tank wall. In particular, it is then important for the heating device in the second assembly opening to close in a fluid-tight manner to the tank wall, so that no leakage of fuel from the tank occurs.
  • Such a detachable integration of the at least one heating device facilitates repair measures or the integration of other heating devices if the freezing behavior or the thawing behavior of the motor vehicle subsequently changes.
  • the tank has a height and the at least one heating device has a length, and that the length extends at least over 40% of the height. Preferably, the length even extends over at least 70% or even over 100% of the height of the tank.
  • a heater extending over a large portion of the height of the tank is capable of melting an opening in such a closed ceiling, regardless of the height of the closed ceiling in the tank. If for reasons of stability (for example, in motor vehicles for the off-road area) no very long heating device may be desired, this z.

  • openings, pores, channels or the like may be provided, which optionally also allow a flow through the heater with liquid fuel.
  • a heating device designed in the manner of a plate represents a considerable flow resistance for operating fluid in the tank. For this reason, it is advantageous to carry out the heating device permeable to liquid operating fluid at least in certain areas.
  • the at least one heating device forms a heatable cage around the conveyor device.
  • the heater separates the conveyor from the rest of the interior of the tank.
  • a partial permeability of the heating device for liquid fuel is then required so that fuel from the remaining interior of the tank can get to the conveyor.

For example, these may be arranged in the immediate vicinity of a location at which a particularly rapid freezing is expected with a predetermined pattern. It is also possible to provide a three-dimensional grid of temperature sensors for monitoring the freezing behavior in the entire tank. In the monitoring of the freezing behavior, temperature sensors outside the tank can also be included and / or temperature sensors on a conveyor module for conveying fuel out of the tank. Further information, such as the vehicle speed and / or the level, can also be included.
  • a suitable model of the freezing behavior of the fuel tank can be an energy model which takes into account the heat energy stored in the operating fluid and / or the heat flows out of the tank or into the tank.
