The oil pan includes, but is not limited to a base part configured to form an oil sump and a suction channel that opens into the oil sump through an opening. The oil pan also includes, but is not limited to a nose in a region of the opening for at least partly covering a cross section of the suction channel in a horizontal direction of flow.

Claims (26)

1. An oil pan for an internal combustion engine, comprising:

a base part configured to form an oil sump and a suction channel that opens into the oil sump through an opening; and

a nose in a region of the opening for at least partly covering a cross section of the suction channel in a horizontal direction of flow, the nose extending geodetically downwards, wherein the suction channel is slanted downward to the nose.

2. The oil pan according to claim 1 , wherein the nose is substantially perpendicular to the base part.

3. The oil pan according to claims 1 , wherein the nose is integrally connected with the suction channel.

4. The oil pan according to claim 1 , wherein the suction channel is at least partly integrally connected with the base part.

5. The oil pan according to claim 1 , wherein the base part at least partly forms the opening.

6. The oil pan according to claim 5 , wherein the base part is planar in the region of the opening.

7. An internal combustion engine, comprising:

a crankshaft housing; and

an oil pan that is coupled to the crankshaft housing, the oil pan comprising:

a base part configured to form an oil sump and a suction channel that opens into the oil sump through an opening; and

a nose in a region of the opening for at least partly covering a cross section of the suction channel in a horizontal direction of flow, the nose extending geodetically downwards, wherein the suction channel is slanted downward to the nose.

8. The internal combustion engine according to claim 7 , wherein the nose is substantially perpendicular to the base part.

9. The internal combustion engine according to claim 7 , wherein the nose is integrally connected with the suction channel.

10. The internal combustion engine according to claim 7 , wherein the suction channel is at least partly integrally connected with the base part.

11. The internal combustion engine according to claim 7 , wherein the base part at least partly forms the opening.

12. The internal combustion engine according to claim 11 , wherein the base part is planar in the region of the opening.

13. An oil pan for an internal combustion engine, comprising:

a base part configured to form an oil sump and a suction channel that opens into the oil sump through an opening; and

a nose in a region of the opening for at least partly covering a cross section of the suction channel in a horizontal direction of flow, the nose being substantially perpendicular to the base part, wherein the suction channel is slanted downward to the nose.

14. The oil pan according to claim 13 , wherein the nose the nose extends geodetically downwards.

15. The oil pan according to claim 13 , wherein the nose is integrally connected with the suction channel.

16. The oil pan according to claim 13 , wherein the suction channel is at least partly integrally connected with the base part.

17. The oil pan according to claim 13 , wherein the base part at least partly forms the opening.

18. The oil pan according to claim 17 , wherein the base part is planar in the region of the opening.
