Motor vehicle having an internal combustion engine and having an exhaust-gas aftertreatment device, exhaust-gas aftertreatment device for an internal combustion engine, and particle filter

1 . A motor vehicle comprising:

an internal combustion engine; and

an exhaust-gas aftertreatment device comprising a particle filter having a particle filter housing and having a filter body arrangement configured to separate particles from an exhaust-gas flow that is emitted by the internal combustion engine and flows through the filter body arrangement and is received in the particle filter housing,

wherein the filter body arrangement comprises filter body elements that are separated from one another by at least one liquid-tight layer oriented at least substantially in a longitudinal extent direction of the particle filter, wherein the at least one liquid-tight layer extends between and is sealingly connected to opposite regions of the particle filter housing so as to completely separate, in the longitudinal extent direction and a transverse extent direction, filter body elements located geodetically above the at least one liquid-tight layer from filter body elements located geodetically below the at least one liquid-tight layer, and

wherein the at least one liquid-tight layer is configured to form a separating layer for at least one level of a liquid.

2 . The motor vehicle according to claim 1 ,

wherein the at least one liquid-tight layer is oriented at least substantially perpendicular to a direction of action of gravity.

3 . The motor vehicle according to claim 1 ,

wherein the filter body arrangement comprises a plurality of filter body elements, of which in each case two of the filter body elements are separated from one another by at least one liquid-tight additional layer oriented parallel to the at least one liquid-tight layer.

4 . The motor vehicle according to claim 1 ,

wherein the at least one liquid-tight layer and the filter body elements are formed from materials which differ from one another.

5 . The motor vehicle according to claim 4 ,

wherein the material of the at least one liquid-tight layer is metallic.

6 . The motor vehicle according to claim 4 ,

wherein the particle filter comprises at least one projection that is connected to the liquid-tight layer and is introduced into at least one of the filter body elements in a direction of action of gravity.

7 . The motor vehicle according to claim 1 ,

wherein the at least one liquid-tight layer is formed from a material having a greater thermal conductivity than a material of the filter body elements.

8 . The motor vehicle according to claim 1 ,

wherein the at least one liquid-tight layer and the filter body elements are formed from a same material, and the at least one liquid-tight layer has a lower porosity and/or a higher density than the filter body elements.

9 . A particle filter for a motor vehicle comprising:

a particle filter housing; and

a filter body arrangement configured to separate particles from an exhaust-gas flow that is emitted by an internal combustion engine of the motor vehicle and flows through the filter body arrangement and is received in the particle filter housing,

wherein the filter body arrangement comprises filter body elements that are separated from one another by at least one liquid-tight layer oriented at least substantially in a longitudinal extent direction of the particle filter, wherein the at least one liquid-tight layer extends between and is sealingly connected to opposite regions of the particle filter housing so as to completely separate, in the longitudinal extent direction and a transverse extent direction, filter body elements located geodetically above the at least one liquid-tight layer from filter body elements located geodetically below the at least one liquid-tight layer, and

wherein the at least one liquid-tight layer is configured to form a separating layer for at least one level of a liquid.

10 . The particle filter according to claim 9 ,

wherein the at least one liquid-tight layer is oriented at least substantially perpendicular to a direction of action of gravity.

11 . The particle filter according to claim 9 ,

wherein the filter body arrangement comprises a plurality of filter body elements, of which in each case two of the filter body elements are separated from one another by at least one liquid-tight additional layer oriented parallel to the at least one liquid-tight layer.

12 . The particle filter according to claim 9 ,

wherein the at least one liquid-tight layer and the filter body elements are formed from materials which differ from one another.

13 . Particle filter according to claim 12 ,

wherein the material of the at least one liquid-tight layer is metallic.

14 . The particle filter according to claim 12 ,

wherein the particle filter comprises at least one projection that is connected to the liquid-tight layer and is introduced into at least one of the filter body elements in a direction of action of gravity.

15 . The particle filter according to claim 9 ,

wherein the at least one liquid-tight layer is formed from a material having a greater thermal conductivity than a material of the filter body elements.

16 . The particle filter according to claim 9 ,

wherein the at least one liquid-tight layer and the filter body elements are formed from a same material, and the at least one liquid-tight layer has a lower porosity and/or a higher density than the filter body elements.

17 . An exhaust-gas aftertreatment device for an internal combustion engine, comprising:

the particle filter according to claim 9 .
