Description

The present invention relates to an arrangement for a vehicle for filling a fuel and a reducing agent. The vehicle is in particular a diesel-powered road vehicle. The reducing agent is in particular a urea.

A reducing agent is usually injected into the exhaust line of a vehicle and results in a selective catalytic reaction (SCR). Nitrogen oxides and ammonia are converted to water and nitrogen. The tank arrangement of the prior art vehicles considered here comprise two tubes, one of the tubes leading to the fuel tank and one of the tubes leading to the reducing agent tank. The two tubes are accessible in Tankeinfüllopf the vehicle, so that the corresponding dispensing device can be inserted when refueling in the respective tube. The dispensing device is for example a fuel nozzle or the spout of a corresponding storage container.

In the prior art, the two tubes for the fuel and for the reducing agent are formed into two individual filler neck within the Tankeinfüllopfs. This embodiment with the two individual, separate filler neck leads to a relatively large space in Tankeinfüllopf and consequently to a relatively large Tankeinfüllopf.

It is an object of the present invention to provide an arrangement for a vehicle for filling a fuel and a reducing agent, which is designed as possible space-optimized with cost-effective production and easy installation.

The solution of this object is achieved by the features of claim 1. The dependent claims have advantageous embodiments of the invention to the subject.

Thus, the invention is achieved by an arrangement for a vehicle. The arrangement is designed for filling the fuel, in particular diesel, and the reducing agent, in particular urea.

The arrangement comprises a first fluid path for guiding the fuel into a fuel tank and a second fluid path for guiding the reducing agent into a reducing agent tank. The arrangement according to the invention and the two tanks are arranged inside a vehicle. The fluid paths can in particular be formed by tubes, hoses or channels integrated in further components.

Furthermore, the arrangement has a common filler neck with a first portion and a second portion. The first section leads into the first fluid path. The second section leads into the second fluid path. The common filler neck is disposed within a tank filler pot of the vehicle. The first section and the second section are integrated in the common filler neck. This integration of the two sections for filling the two tanks in a common filler neck creates a very small-sized arrangement for filling the fuel and for filling the reducing agent. As a result, the tank filler pot of the vehicle can also be made space-optimized.

For the inventive integration of the two sections in the common filler neck two preferred embodiments are described:
According to the first embodiment, the common filler neck has a first conduit with a first opening and a second conduit with a second opening. In the first opening and thus in the first line, the dispensing device for the fuel can be inserted. In the second opening and thus in the second line, the dispensing device for the reducing agent can be inserted. The dispensing device in particular involves dispensing nozzles or pouring devices of corresponding containers.

The first conduit forms the first section and the second conduit forms the second section of the common filler neck. The integration of the two sections in the common filler neck and thus the space-optimized design is achieved by the lines are formed in a one-piece, non-destructively separable component. This configuration of the two lines in the one component makes it possible to arrange the two lines as close to each other as possible.

Particularly preferably, it is provided to manufacture the one-piece, non-destructively separable component in a common injection molding process or a common casting operation. This results in a component which simultaneously forms the two sections of the filler neck and in which thus the two lines are formed.

Alternatively, it is preferably provided to manufacture the one-piece, non-destructive separable component from two cohesively connected pipes. Through this cohesive connection, the two tubes can be arranged as close to each other as possible. This also creates a very space-optimized arrangement.

According to the second embodiment, it is preferably provided that the filler neck has a common line. This one common line has only one common opening into which either the fuel dispensing device and the reducing agent dispensing device are selectively inserted. This one common line thus forms at the same time the first section and the second section, integrated in the common filler neck.

In the filler neck, a valve arrangement is provided to selectively connect the common line to the first fluid path and the second fluid path.

The valve arrangement is preferably designed as a flap which, depending on the position, closes one fluid path and opens the other fluid path. By using the common conduit and the valve assembly, it is possible that the filler neck has only one opening. Accordingly, only the installation space for an opening must be provided in the tank filler pot. Both dispensing devices are optionally inserted in the same opening.

The openings of the common line is preferably designed for arranging a closure cap, in particular for screwing on a closure cap.

The arrangement in the second embodiment preferably comprises a recognition device. The detection device is designed to recognize or differentiate the refueling with fuel and reducing agent and thus to control the valve arrangement accordingly.

Preferably, the recognition device can be actuated by the respectively inserted dispensing device. This actuation can be mechanical and / or magnetic. For this purpose, the dispensing devices for the fuel and for the reducing agent preferably have different geometries. These different geometries actuate the detection device in a different manner when inserted, so that the two dispensing devices can be distinguished from each other.

Instead of or in addition to the configuration of the different geometries, it is also preferable for at least one of the two dispensing devices to comprise a magnetic arrangement, wherein the detection device is actuated when the dispensing device is inserted by means of the magnetic arrangement.

Furthermore, it is preferably provided that the detection device is designed for electronic data exchange with the dispensing device, so as to distinguish the dispensing device associated with the fuel from the dispensing device associated with the reducing agent. This electronic data exchange takes place in particular wirelessly, for example via an RFID chip on the dispensing device.

The invention preferably also comprises a combination of the arrangement described according to the invention and at least one of the two dispensing devices, which is designed for recognition by the recognition device.

Furthermore, it is preferably provided that the detection device is designed to optically or electrochemically detect the introduced fluid, namely fuel or reducing agent, in order to control the valve arrangement based on the detected fluid.

In this case, the corresponding fluid can be detected both directly and also a gas occurring from the fluid. In the case of optical detection, in particular the spectrum of the light of the fluid or gas is analyzed. In the case of electrochemical detection, in particular the conductivity of the fluid or gas is analyzed.

Preferably, the valve arrangement is positioned such that the dispensing device for the fuel past the valve arrangement can be inserted into the first fluid path. Additionally or alternatively, the valve arrangement is preferably positioned so that the dispensing device for the reducing agent can be inserted past the valve arrangement and into the second fluid path. In this embodiment, the corresponding dispensing device is inserted so far, so that the fluid exits downstream of the valve assembly.

Alternatively, it is also possible to design and position the valve arrangement such that at least one of the fluids exits the dispensing device in front of the valve arrangement, flows through the valve arrangement and is thus guided into the associated fluid path.

Further details, features and advantages of the invention will become apparent from the following description and the figures. Show it:

1 a schematic representation of an inventive arrangement according to a first embodiment, and

2 a schematic representation of the arrangement according to the invention according to a second embodiment.

According to 1 includes the arrangement 1 a first fluid path 4 and a second fluid path 5 , The first fluid path 4 leads to a fuel tank 2 of the vehicle. The second fluid path 5 leads to a reducing agent tank 3 of the vehicle.

A tank filler pot is purely schematic 7 of the vehicle. The tank filler pot 7 is usually embedded in the body of the vehicle. In the tank filler 7 there is a common filler neck 6 for the fuel and for the reducing agent.

The filler neck 6 includes a first section 8th and a second section 9 , These two sections 8th . 9 are in the filler neck 6 integrated. The first paragraph 8th is formed by a first line 16 , The second section 9 is formed by a second line 17 , The first line 16 has a first opening 10 on. The second line 17 has a second opening 11 on.

In the first opening 10 is a dispensing device for the fuel plugged. In the second opening 11 a dispensing device for the reducing agent can be inserted. Preferably, both openings 10 . 11 designed for mounting of caps.

For the integrative training of the two sections 8th . 9 in the common filler neck 6 are the two wires 16 . 17 along a connection area 12 connected with each other. This connection over the connection area 12 is either by a common injection molding or casting process for both lines 16 . 17 or achieved a cohesive connections. This creates a non-destructive releasable connection.

The connection area 12 preferably starts directly at the two openings 10 . 11 and preferably extends over the entire length of the filler neck 6 , In 1 is a connection length 13 of the connection area 12 located. Preferably, the connection length is 13 at least 5 cm, in particular at least 10 cm. This will make a sturdy filler neck 6 reached.

In the embodiment according to 2 are the first section 8th and the second section 9 through a common line 18 educated. This joint leadership 18 only has a common opening 14 on. In the common opening 14 and thus in the joint leadership 18 the dispensing device is plugged in both for the fuel and for the urea. The insertion of the two dispensing devices takes place sequentially and not simultaneously. In the tank filler pot 7 is thus only one opening, namely the common opening 14 visible, noticeable. It only needs a cap 15 for closing the common opening 14 ,

In the filler neck 6 according to 2 is a valve assembly 19 arranged. The valve arrangement 19 includes in particular a flap 20 at an axis of rotation 21 is arranged pivotally. Depending on the position of the valve assembly 19 is the path to the first fluid path 4 or to the second fluid path 5 open.

When positioning the valve assembly 19 relatively close to the common opening 14 , it is possible to use the appropriate dispensing device on the valve assembly 19 to push past, so that the corresponding fluid, the dispensing device only downstream of the valve assembly 19 leaves.

Equally preferred is provided that the valve assembly 19 relatively far from the common opening 14 is removed, so that the corresponding fluid the associated dispensing device even before the valve assembly 19 leaves and thus the fluid valve assembly 19 flows through.

Preferably, the filler neck comprises 6 according to the embodiment in 2 a recognition device, not shown. The detection device is designed to recognize or differentiate the refueling with fuel and reducing agent and to control the valve arrangement accordingly.
