Abstract

An intake module an internal combustion engine of a motor vehicle includes at least one air duct element via which air is to be supplied to the internal combustion engine, and a cylinder head cover connected to the air duct element by means of which a cylinder head of the internal combustion engine is to be at least partially covered. A lubricant separation device and a cooling device for cooling the air are integrated into the intake module.

First claim

The invention claimed is:

1. An intake module for a motor vehicle internal combustion engine, the intake module comprising:
an air duct element configured to supply air to the internal combustion engine of the motor vehicle;
a cylinder head cover, connected to the air duct element, wherein the cylinder head cover at least partially covers a cylinder head of the internal combustion engine of the motor vehicle;
a lubricant separation device;
a cooling device configured to cool the air,
wherein the air duct element, cylinder head cover, lubricant separation device and cooling device form a single part;
a first connecting flange surface via which the air duct element is connected to the cylinder head; and
a second connecting flange surface via which the cylinder head cover is connected to the cylinder head,
wherein the first and second connecting flange surfaces are situated at least essentially in a shared plane.

2. The intake module of claim 1 , wherein the air duct element includes an air distributor configured to distribute the air over a plurality of combustion chambers of the internal combustion engine.

3. The intake module of claim 1 , wherein the cooling device is situated in a receiving chamber that is delimited partially by the air duct element and partially by the cylinder head cover.

4. The intake module of claim 1 , further comprising:
at least one air line configured to supply the air to the internal combustion engine, wherein the at least one air line is delimited partially by the air duct element and partially by the cylinder head cover.

5. The intake module of claim 1 , wherein the cooling device is arranged in its longitudinal direction in the intake module.

6. An intake module for a motor vehicle internal combustion engine, the intake module comprising:
an air duct element configured to supply air to the internal combustion engine of the motor vehicle;
a cylinder head cover, connected to the air duct element, wherein the cylinder head cover at least partially covers a cylinder head of the internal combustion engine of the motor vehicle;
a lubricant separation device; and
a cooling device configured to cool the air,
wherein the air duct element, cylinder head cover, lubricant separation device and cooling device form a single part,
wherein the single part has an upper housing part and a lower housing part, wherein the upper housing part and the lower housing part are connected to one another by screwing, welding, gluing, or riveting, and wherein the air duct element, cylinder head cover, lubricant separation device and cooling device are disposed within the upper housing part and the lower housing part.

7. An intake module for a motor vehicle internal combustion engine, the intake module comprising:
an air duct element configured to supply air to the internal combustion engine of the motor vehicle;
a cylinder head cover, connected to the air duct element, wherein the cylinder head cover at least partially covers a cylinder head of the internal combustion engine of the motor vehicle;
a lubricant separation device; and
a cooling device configured to cool the air,
wherein the air duct element, cylinder head cover, lubricant separation device and cooling device form a single part,
wherein the single part has an upper housing part and a lower housing part, wherein the upper housing part and the lower housing part are at least partially formed together as one piece, and wherein the air duct element, cylinder head cover, lubricant separation device and cooling device are disposed within the upper housing part and the lower housing part.

8. An internal combustion engine, comprising:
a cylinder head; and
an intake module, which comprises
an air duct element configured to supply air to the cylinder head;
a cylinder head cover, connected to the air duct element, wherein the cylinder head cover at least partially covers the cylinder head;
a lubricant separation device;
a cooling device configured to cool the air,
wherein the air duct element, cylinder head cover, lubricant separation device and cooling device form a single part;
a first connecting flange surface via which the air duct element is connected to the cylinder head; and
a second connecting flange surface via which the cylinder head cover is connected to the cylinder head,
wherein the first and second connecting flange surfaces are situated at least essentially in a shared plane.

9. The internal combustion engine of claim 8 , wherein the air duct element includes an air distributor configured to distribute the air over a plurality of combustion chambers of the internal combustion engine.

10. The internal combustion engine of claim 8 , wherein the cooling device is situated in a receiving chamber that is delimited partially by the air duct element and partially by the cylinder head cover.

11. The internal combustion engine of claim 8 , wherein the intake module further comprises:
at least one air line configured to supply the air to the internal combustion engine, wherein the at least one air line is delimited partially by the air duct element and partially by the cylinder head cover.

12. The internal combustion engine of claim 8 , wherein the cooling device is arranged in its longitudinal direction in the intake module.

13. An internal combustion engine, comprising:
a cylinder head; and
an intake module, which comprises
