Description

The invention relates to a vehicle container system for a resource, in particular water, which is to be treated at least once in the vehicle with regard to possible biological contaminants. The prior art is by way of example on the GB 2 357 318 A or on the US 6,698,387 B1 directed.

For various reasons, it may be provided to supply not only fuel and air to an internal combustion engine functioning as a drive unit of a vehicle or motor vehicle but also, in particular, to the supplied air flow, at least as a function of operating point, in small amounts. This water is to carry as well as the fuel in the vehicle in a reservoir, but over a certain minimum period stored water, however, known to tend to pollute increasingly due to contained therein biological contaminants. While fresh water is usually suitable to be supplied via an injection device or the like. Of the internal combustion engine or the supplied air flow, this is not true for example for several days stored water - unless it would only distilled water used, but in the daily practice, at least in passenger cars can not be guaranteed.

In the prior art mentioned above, water, which in any way, for example. Via an ultrasonic atomizer ultimately the internal combustion engine is supplied, previously suitable filter and, for example, to undergo a reverse osmosis, which can be removed very well biological contaminants , Incidentally, it is also known in this connection to protect the membrane controlling the reverse osmosis process from chemical damage (for example by chlorine) by means of an activated carbon filter.

Although the above-mentioned technology works well, it is desirable to have another or additional economically viable technology for treating or rendering harmless biological contaminants in a vehicle vessel system-based resource, particularly water. Such a technology should be pointed out hereby (= object of the present invention).

The solution to this problem arises with the features of claim 1 and is characterized by a heating device which passes the entering into a container resources. This heating device is designed to heat the passing equipment to the extent that contained therein biological contaminants as far as possible, d. H. Best possible or as far as possible be killed. Advantageous embodiments and further developments of the invention are the subject of the dependent claims.

In principle, biological contaminants (in water) could have been rendered harmless by boiling down the equipment (water), but the obvious solution is that of all the water already in the reservoir - in the following, only water will be used without limiting the "equipment" to it want - to boil, extremely uneconomical and in particular required a powerful heater or heating device with then forcibly high energy consumption, which can not be easily covered on motor vehicles, especially passenger cars. In contrast, considerably more economical and also less expensive, it is only that resource or the amount of resources that is supplied to a container in the vehicle to heat in the course of this feeding and quasi boil it. Thus, the water passes through a properly designed or dimensioned water heater (in view of the desired killing of bacteria, microbes, fungi, algae, spores, etc., which are examples of biological contaminants before the water is properly treated and enters the vessel.

Water heaters in particular for water are basically known, wherein for the present application in a motor vehicle primarily an electrical, d. H. is proposed from the electrical vehicle electrical system with electrical energy powered water heater. In this context it should be mentioned that the container for the water (or equipment) or possibly provided in the vehicle container for the water (this will be discussed in more detail below) in turn can be designed to be heated to the water, which in a If the vehicle parked at lower ambient temperatures freezes, thaws again, but this latter heater, which may also be designed as an electric heater, slightly different than the heating device according to the invention. In particular, a previously mentioned container heater - unlike a water heater or the like according to the invention ("heating device") - is not designed to heat the water contained therein so much that biological contaminants contained therein are killed.

According to an advantageous development, two containers are arranged in the vehicle spatially separated from each other in the vehicle and it is the heating device on or in one of the two container volumes interconnecting Transfer line provided. In particular, a relatively small container can be provided close to the consumer, ie near the internal combustion engine in the so-called engine compartment provided in the front region of the motor vehicle, while a larger container, for example, is located in the rear region of the motor vehicle, where more installation space is available. In this case, the smaller container in Fzg.-engine compartment does not have its own tank heater, as contained therein frozen water alone by the radiant heat of the engine in time, ie before it is needed after restarting a parked at cold ambient temperatures vehicle thaws. Alternatively, a container heating via the coolant of the internal combustion engine is possible here. Usually, however, a larger, for example, in the vehicle rear area and thus consumer remote arranged container will have its own electric container heating. It is now proposed to provide a heating device according to the invention on or in a transfer line between the two containers, in which usually also a pump or generally conveying device is provided for conveying the water from the larger container into the smaller container. Alternatively or additionally, a return line may be provided with a return pump or the like between these two containers, in or on which return line a (possibly single) heating device is located. Such a design is particularly advantageous, since at longer distances of the vehicle usually sufficient available electrical energy can be used to quasi circulate the water (or equipment) between the two (or more generally) containers and in each case when passing the heating device decontaminate, ie suitable to treat biological contaminants, ie sufficient to heat.

The accompanying schematic diagrams point to the essential abstrahiert embodiments of the invention. It is with the reference number 1 Always a container in a motor vehicle, not shown, in which a resource and especially water, which resources could contain biological contaminants, is included, which can be supplied to the combustion chambers of an internal combustion engine, also not shown or should. Representing the internal combustion engine here is an injection rail 2 represented, from which injectors are derived or supplied, which are able to inject water in metered small amount in the individual engine cylinders associated intake air lines. For this leads from the container 1 a supply line 3 to the injection rail 2 , in which supply line 3 a conveyor 4a and downstream of this a filter 5a is provided. Another filter unit 5b is located at the beginning of this supply line 3 here in the container 1 ,

Even if the water is in the container for a longer period of time 1 there is no appreciable contamination by biological contaminants or by growth and multiplication of biological contaminants in it in the container 1 to have located water is on a supply line 6 to the container 1 , over or through which water from the outside, ie from the vehicle environment into the container 1 is fillable, a heating device 7 provided, which by the supply line 6 this heating device 7 Passing water heated so far that it contained biological contaminants are largely destroyed.

According to the embodiment 1 is a single container 1 intended. The feed line 6 this container 1 points to her the container 1 facing away from the free end of a filler neck 8th with venting device for the container being suitably provided therein 1 or its storage volume.

In the embodiments of the 2 and 3 are two containers 1a . 1b provided, of which a smaller container 1a close to the consumer, ie here near the fuel rail 2 is provided while the other larger container 1b consumer remote is arranged. From the consumer-remote container 1b leads a transfer line 9 , in which a (further) conveying device 4b is provided to the smaller consumer near container 1a from which the supply line 3 (analogous 1 ) to the injection rail 2 leads. After consumption of in the containers 1a . 1b stored water can be the larger container 1b from the outside via a supply line 6 (with provided filler neck 8th ) are charged with fresh water. This via the feed line 6 supplied water can indeed analog 1 a heating device, but this is in the embodiments of the 2 and 3 not shown or not provided.

Rather, the embodiment is after 2 a heating device according to the invention 7 for killing biological contaminants in a heating device 7 passing water flow in said transfer line 9 through which the (further) conveying device 4b Water from the larger container 1b in the smaller container 1a promotes. At the beginning of this transfer line 9 is here in the container 1a (similar to the container 1 from 1 ) a filter unit 5b intended.

According to the embodiment 3 is a heating device according to the invention 7 not in the transfer line 9 provided - albeit there may be provided there - but in a return line 10 , by which by means of another conveyor 4c Water from the smaller container 1a in the larger container 1b can be promoted back. This embodiment makes it possible in a particularly advantageous manner, as already briefly explained before the description of the figure, in particular during prolonged operation of the motor vehicle to circulate the stored water quasi continuously and thereby safely and completely (ie in particular in both containers 1a and 1b to decontaminate water) with respect to biological contaminants.
