Description

Fuel System for a Vehicle The invention relates to a fuel system according to the preamble of patent claim 1.
Such a fuel system for a vehicle is known from US 5 303 842. The fuel system comprises at least one fuel tank for storing fuel. For example, the fuel is a liquid fuel used for operating an internal combustion engine of the vehicle. The fuel system further comprises at least one filling duct. The filling duct serves for filling fuel to be stored in the fuel tank into the fuel tank. This means fuel to be stored in the fuel tank can flow through the filling duct and is guided into the fuel tank by means of the filling duct.
Moreover, the fuel system comprises at least one quantity sensor arranged in the filling duct. The quantity sensor is capable of measuring a quantity of the fuel flowing through the filling duct into the fuel tank.
US 2009/0057036 Al shows a precision gauge for liquid fuel in a vehicle's tank, the precision gauge comprising a precision electronic scales which is connected to the vehicle's fuel tank. The precision gauge further comprises a computer that based on -as first information -the fuel tank's weight with its contents previous to the loading, and on the information received from the scales, and on the corresponding density previously entered in the computer determines the volume of loaded fuel that can be noticed in a display located in a vehicles board.
Furthermore, US 6615656 Bi shows a method for measuring the volume of a liquid in a fuel tank in a vehicle that is subject to varying external forces caused by movement or charges in the roll and pitch of the vehicle.
It is an object of the present invention to provide a fuel system of the kind indicated in the preamble of patent claim 1, by means of which fuel system the actual quantity of fuel flowing through the filling duct when filling the fuel tank can be determined particularly precisely and easily.
This object is solved by a fuel system having the features of patent claim 1.
Advantageous embodiments with expedient and non-trivial developments of the invention are indicated in the other patent claims.
In order to provide a fuel system of the kind indicated in the preamble of patent claim 1, by means of which fuel system the quantity of the fuel flowing through the filling duct when filling the fuel tank can be determined particularly precisely and easily, according to the present invention, the fuel system comprises at least one quality sensor capable of measuring at least one quality parameter characterizing the quality of the fuel flowing through the filling duct in the fuel tank. Thereby, the quality parameter can be used to determine the quantity of the fuel. This means the quantity of the fuel can be determined by using the quantity sensor as well as the quality sensor. Thus, the amount of fuel flowing through the filling duct into the fuel tank can be determined particularly easily and precisely. For example, the determined quantity of the fuel can be displayed on a display which is arranged on, for example, a dashboard in the interior of the vehicle. Moreover, the determined quality of the fuel can be displayed.
Advantageously, the display is configured as a digital display capable of numerically displaying the amount of the fuel stored in the fuel tank. Hence, the driver of the vehicle can read the amount of fuel stored in the fuel tank very precisely. By numerically displaying the amount of the fuel the amount of the fuel can be displayed more precisely in comparison with an analogue gauge or a bar indicator. Thus, a precise numerical indication of the amount of fuel stored in the fuel tank can be provided by means of the fuel system.
The quality sensor can measure any kind of fuel quality. For example, the quality sensor is configured to measure a density of the fuel. Additionally or alternatively, the quality sensor is configured to measure a proportion of suspended particles in the fuel, content of sulphur and/or other components and/or additives in the fuel. The quality sensor may be of any kind but, preferably, should be as simple as possible to keep the costs particularly low.
For example, the quantity sensor is configured as fuel flow sensor by means of which the amount of fuel flowing through the filling duct can be measured.
Further advantages, features, and details of the invention derive from the following description of a preferred embodiment and from the drawing. The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone can be employed not only in the respective indicated combination but also in other combination or taken alone without leaving the scope of the invention.
The drawing shows in: Fig. 1 a schematic and sectional side view of a fuel system for a vehicle, the fuel system comprising a fuel tank, a filling duct, a quantity sensor capable of measuring a quantity of the fuel flowing through the filling duct, and a quality sensor capable of measuring at least one quality parameter characterizing the quality of the fuel flowing through the filling duct into the fuel tank; and Fig. 2 a schematic front view of a dashboard of a vehicle, wherein a digital display for numerically displaying the amount of fuel is arranged on the dashboard.
Fig. 1 shows a fuel system 10 for a vehicle. The vehicle is configured as a motor vehicle and comprises at least one engine which is configured as an internal combustion engine.
For example, the vehicle is a passenger vehicle for a truck. The fuel system 10 comprises a fuel tank 12 having a receiving space 14 in which fuel can be stored. For example, the fuel is a liquid fuel in the form of diesel or petrol, the fuel serving for operating the engine.
For this purpose, the fuel stored in the fuel tank 12 is conveyed from the fuel tank 12 to the engine by means of at least one fuel pump.
The fuel system 10 further comprises a filling duct 16 via which fuel to be stored in the fuel tank 12 can be filled into the fuel tank 12. This means fuel flowing through the filling duct 16 is guided into the receiving space 14 by means of the filling duct 16. As can be seen from Fig. 1, at least a portion 18 of the filling duct 16 is arranged inside the fuel tank 12.
The fuel system 10 further comprises a quantity sensor 20 arranged in the filling duct. As can be seen from Fig. 1, the quantity sensor 20 is arranged in the portion 18 and, thus, inside the fuel tank 12. The quantity sensor 20 is configured as a fuel flow sensor and, thus, capable of measuring a quantity of the fuel flowing through the filling duct 16 into the fuel tank 12.
The fuel system 10 comprises a quality sensor 22 arranged in the filling duct 16. The quality sensor 22 is arranged in the portion 18 and, thus, inside the fuel tank 12. In the present case, the quality sensor 22 is arranged downstream of the quantity sensor 20 with respect to the direction of flow of the fuel flowing through the filling duct 16 into the fuel tank 12. In other words, the quantity sensor 20 and the quality sensor 22 are arranged at the inlet of the fuel tank 12 so that the amount of fuel filled into the fuel tank 12 and the density of the fuel can be detected very precisely.
The quality sensor 22 is configured as a fuel density sensor and, thus, capable of measuring the density of the fuel flowing through the filling duct 16. The density of the fuel is a quality parameter characterizing the quality of the fuel flowing through the filling duct 16. In other words, the quality sensor 22 is capable of measuring at least one quality parameter characterizing the quality of the fuel flowing through the filling duct 16 into the filling tank 12.
By means of the quantity sensor 20 and the quality sensor 22 the actual amount of fuel flowing through the filling duct 16 into the fuel tank 12 can be determined very easily and precisely. For example, the quantity sensor 20 and the quality sensor 22 send at least one signal indicative of the quality parameter and/or the measured amount of the fuel to a display arranged on a dashboard in an interior of the vehicle, the display being capable of displaying the amount of the fuel and/or at least one value of the quality parameter. Thus, the driver of the vehicle can read the amount of fuel stored in the fuel tank 12 and/or the quality of the fuel very easily.
Fig. 2 shows a dashboard 24 of the vehicle. Fig. 2 also shows an instrument cluster 26 arranged on the dashboard 22. The instrument cluster 26 comprises a display which is configured as a digital display 28 capable of numerically displaying the amount of fuel stored in the fuel tank 12. As can be seen from Fig. 2, the digital display 28 comprises three digits by means of which the amount of fuel stored in the fuel tank 12 can be displayed.
