Abstract

An exhaust gas after-treatment device includes: a catalytic converter system, which includes a delivery side and a discharge side; and a container including an interior space and at least two openings, the at least two openings including a first opening and a second opening, the catalytic converter system being arranged in the interior space of the container, the first opening being connected with the catalytic converter system on the delivery side, and the second opening being connected to the catalytic converter system on the discharge side.

First claim

What is claimed is:

1. An exhaust gas after-treatment device, comprising:
a catalytic converter system, which includes a delivery side and a discharge side; and
a container including an interior space, at least two openings, and a container top, the at least two openings including a first opening and a second opening, the catalytic converter system being arranged in the interior space of the container, the first opening being connected with the catalytic converter system on the delivery side, and the second opening being connected to the catalytic converter system on the discharge side, the first opening and the second opening being positioned at the container top.

2. An exhaust gas after-treatment device according to claim 1 , further comprising a working platform, the working platform being arranged on the container top of the container.

3. An exhaust gas after-treatment device according to claim 2 , wherein the working platform includes a non-slip floor.

4. An exhaust gas after-treatment device according to claim 2 , wherein the working platform includes a foldable railing.

5. An exhaust gas after-treatment device according to claim 1 , further comprising an exhaust gas stack which—at least in one operating state of the exhaust gas after-treatment device—is mounted outside of the container at the second opening.

6. An exhaust gas after-treatment device according to claim 1 , wherein the container includes at least one rail arrangement, at least part of the catalytic converter system being movably located on the rail arrangement.

7. An exhaust gas after-treatment device according to claim 1 , wherein the catalytic converter system includes a catalytic converter device, the catalytic converter system including a fresh air supply device configured for supplying a fresh air, the fresh air supply device including a first flow opening which is fluidically connected at least indirectly to the catalytic converter device of the catalytic converter system, and the fresh air supply device including a second flow opening which is structured and arranged for a fluidic connection with, and is fluidically connected with, a fresh air source.

8. An exhaust gas after-treatment device according to claim 1 , wherein the catalytic converter system includes an SCR catalytic converter, the exhaust gas after-treatment device further including at least one reducing agent reservoir and a reducing agent supply line, the at least one reducing agent reservoir being arranged in the interior space of the container and being connected to the catalytic converter system via the reducing agent supply line.

9. An exhaust gas after-treatment device according to claim 8 , further comprising a compressed air device, which is located in the interior space, is configured for injecting a reducing agent, and is operatively connected to reducing agent supply line.

10. An exhaust gas after-treatment device according to claim 1 , further comprising a controller which is structured and arranged for controlling the catalytic converter system and is located in the interior space.

11. An exhaust gas after-treatment device according to claim 1 , wherein the exhaust gas after-treatment device is a vehicle or a vehicle trailer.

12. An internal combustion engine, comprising:
an exhaust gas after-treatment device, including:
a catalytic converter system, which includes a delivery side and a discharge side; and
a container including an interior space, at least two openings, and a container top, the at least two openings including a first opening and a second opening, the catalytic converter system being arranged in the interior space of the container, the first opening being connected with the catalytic converter system on the delivery side, and the second opening being connected to the catalytic converter system on the discharge side, the first opening and the second opening being positioned at the container top; and
an exhaust gas outlet which is fluidically connected to the first opening of the exhaust gas after-treatment device.
