Abstract

The invention relates to a display device for emission parameters of an internal combustion engine with a linear representation of a value range, wherein a first and a second part region are provided for the display of difference values with differing sign relative to a given set value.

Claims

1. A display device for emission parameters of an internal combustion engine, comprising:

a line providing a linearly displayed value range;

a marker that is movable along the line; and

a marker that is fixed along the line,

wherein the value range comprises a first subrange for displaying positive values and a second subrange for displaying negative values.

2. The display device as claimed in claim 1, characterized in that the movable marker is formed by the tip of a pointer that is physically present or embodied as a graphic symbol.

3. The display device as claimed in claim 1, wherein the movable marker is embodied by influencing an optical property of one or more neighboring elements that are provided in a fashion fixed along the value range line.

4. The display device as claimed in claim 1, wherein the fixed marker is arranged at the division point between the subranges of the value range.

5. The display device as claimed in claim 1, wherein the value range has scaling.

6. The display device as claimed in claim 5, the scaling is implemented either proportionally or non-proportionally or as a mixed form composed of these two possibilities.

7. The display device as claimed in claim 5, wherein the scaling is designed in a way that can be altered.

8. The display device as claimed in claim 6, wherein the scaling is designed in a way that can be altered.
