Definitions
- the invention relates to a fuel system with a fuel tank and a main flow branch through which a fluid mixture can flow and which opens into the fuel tank.
- a separating device for a fluid containing the fluid mixture is arranged in the main flow branch.
- Exhaust gas purification processes are caused in particular by the fact that such a quantity is present between the amount of pollutants that arise during combustion
- Polyoxymethylene dimethyl ether also called oxymethylene ether or OME in short. OME burns almost soot-free, which means that the combustion process in the engine is reduced to one
- Fuel vapors are known, such as in DE 10 2012 018 558 A1
- Tank ventilation system In order to prevent fuel vapors consisting of unburned hydrocarbons from escaping into the environment, this has an adsorption filter which is usually used for this purpose. To prevent water from entering and the associated corrosion of the adsorption filter or
- Impairment of the adsorption material arranged in the adsorption filter is
- Ambient air supply ventilation line arranged in the interior of the motor vehicle, so that it is essentially protected from external weather conditions.
- the adsorption filter has a seal, which expands when it comes into contact with water and thereby closes a ventilation channel of the adsorption filter in such a way that the adsorption material arranged in a receiving space downstream of the channel of the seal does not come into contact with the water entering the ventilation channel on the inlet side can reach.
- both of the above publications describe ventilation systems which are not suitable for venting a tank.
- DE 10 2014 010 728 A1 discloses a tank ventilation filter for connection to a fuel tank, which essentially consists of a constriction, downstream of the constriction of air drawn in in the direction of flow
- Sedimentation chamber and a particle filter consisting of a fiber material is constructed.
- the constriction and the sedimentation chamber are
- Separation of water entering the filter with the sucked-in air is provided, which primarily serves to protect the particle filter against moisture and only secondarily to protect the tank contents from penetrating water.
- the separation of the water also takes place unspecifically and not to a large extent, since the change in cross-section and therefore the pressure increase is not sufficient for pressure change separation, which means that the tank ventilation filter is only suitable for condensing moisture, such as during rain events.
- the invention has for its object to design the fuel system of the type mentioned in such a way that water or
- a fuel system in particular for storing and supplying fuel to an internal combustion engine of a motor vehicle, which has a fuel tank and a main flow branch through which a fluid mixture can flow and which opens into the fuel tank, the main flow branch in particular being designed to be exclusively through-flowable.
- a separating device for a fluid containing the fluid mixture is also arranged in the main flow branch.
- this fluid is a reaction fluid which chemically reacts with the fuel, parts and / or constituents of the fuel, the chemical reaction of the fuel, parts and / or constituents of the fuel also being able to take place in a chemical chain reaction. For separating and receiving this chemically with the fuel, parts and / or
- the separating device has constituents of the reaction fluid that reacts with fuel Storage element, whereby the supply, penetration or introduction of the reaction fluid to or into the fuel can be completely or almost completely eliminated.
- it is arranged upstream of the fuel tank in the main flow branch or, starting from the supply of the fluid mixture and an associated flow in the direction of the fuel tank, upstream of the fuel tank.
- the separating device arranged in the main flow branch also forms a component of the main flow branch. It is conceivable here that the main flow branch has further components arranged in the main flow branch, at least some of the components of the
- Main flow branch should be fluidly connected to one another via lines.
- the fluid mixture consists of at least two fluids, one of which is the reaction fluid.
- a fluid is considered to be of a single type, as a result of which the fluid mixture could be made up of an atomically or molecularly present gas and the reaction fluid.
- the fluid mixture consists of more than two fluids, the fluid mixture usually being air present in the atmosphere surrounding the fuel system.
- the fluid that forms the reaction fluid is regularly water in the air in liquid and / or gaseous phase, the water in the gaseous phase accordingly being present as water vapor. If the fluid mixture is configured as air in such a constellation, the supply of the fluid mixture is the ventilation of the fuel tank with air, which the water or the water vapor by means of the
- the storage element is a
- Adsorber or absorber but in a preferred embodiment the storage element is designed as an adsorber.
- Such an embodiment of the storage element as an absorber or preferably an adsorber enables complete or almost complete separation and absorption of the reaction fluid in the adsorber or absorber.
- the adsorber should contain an adsorbent or also an adsorbent, which preferably has a porous or highly porous structure and / or the reaction fluid with high selectivity, e.g. B. in the form of water and / or water vapor, but none or almost none
- Hydrocarbons or fuel binds Hydrocarbons or fuel binds.
- a filler device which enables a supply of fuel through a fuel line connected to the fuel tank to the fuel tank containing fluid mixture.
- the filling device is generally a tank neck arranged on a motor vehicle for the purpose of the refueling process.

- Biofuel obtained from raw materials. This applies in particular to so-called biodiesel, which has a hygroscopic effect.
- fuel filters are usually integrated into the fuel filter
- Water separator used. However, it cannot be ruled out that water or water vapor will be entrained from these and be present again in the fuel. To avoid a reaction with the fuel, parts and / or components of the fuel contained in the fuel tank, it is considered profitable to separate the reaction fluid, which is present, for example, in the form of water or water vapor, from the fuel returned to the fuel tank. Likewise, the separation device can be provided to separate reaction products which have already been converted from the fuel to be recycled.
- the fuel system is also designed in such a way that it has at least two separating devices, which can be flowed through in particular in the main flow branch, z. B. always in the event of a defect or malfunction of a separation device or in the case of regeneration of a separation device, separation and absorption of the reaction fluid from the fluid mixture can be ensured. It should be noted here that preferably only two separating devices in the fuel system and these particularly preferably in the main flow branch parallel to one another
- an embodiment of the invention is to be regarded as advantageous, in which the storage element is exchangeably arranged in the separating device, whereby an exchange of the storage element is made possible, for example, in the event of a defect or a malfunction, but especially if the storage element is saturated with the reaction fluid.
- the storage element can be used to ensure exchangeability
- the separating device can thus be designed as an interchangeable cartridge system.
- the separating device has a regeneration device for releasing the reaction fluid received in the storage element, wherein a possible embodiment of the regeneration device can be a heating device expelling the reaction fluid from the storage element.
- the regeneration device can be a heating device expelling the reaction fluid from the storage element.
- the fuel system also has at least one fuel vapor retention system arranged in the main flow branch - in particular through which the separating device or the separating devices can flow, or alternatively the separating device has a separating element that stores fuel vapors, then this can be seen as a very promising embodiment of the invention, in addition to the supply of
- Reaction fluid in the fuel prevents fuel vapors from escaping from the fuel tank.
- the fuel vapor retention system if arranged in the main flow branch, would also be regarded as a component of the main flow branch.

- the fuel system 1 is designed such that the fluid mixture is supplied to the fuel tank 2, that is to say, the fuel tank 2 is vented with air from the atmosphere surrounding the fuel system 1 exclusively via the main flow branch 3 and thus via the separating device 4. This is also achieved in that in the main flow branch 3 between the
- the armature 14 influencing the flow of the fluid mixture in the form of air and shaped as a reusable valve, and furthermore the armature 14 shaped as a reusable valve via one
- Aeration line 15 forming secondary flow branch is connected to the filling device 7.
- the delivery device 13 which is also arranged in the main flow branch 3 in front of the separating device 4, and a switching position of the fitting 14 designed as a returnable valve, which is a
- a second switching position, here a blocking division, of the valve 14 designed as a reusable valve also enables the storage element 5 to be regenerated with the regeneration device 12 of the separating device 4 designed as a heating device, without the expelled from the storage element 5
- Reaction fluid in the form of water vapor enters the fuel tank 2 and is released into the atmosphere surrounding the fuel system 1.
- the reusable valve is in a switch position open in the direction of the fuel tank 2, so that the fuel tank 2 can be ventilated with steam-free air.
- the fuel system 1 now also has the flow 9 to the internal combustion engine 8 and return 10 from the internal combustion engine 8, the transport of the fuel from the fuel tank 2 being initiated by the fuel delivery unit 16.
- the separating device 11 for separating reaction fluid, water or water vapor, which may have been carried into the fuel is arranged.
