Abstract

An intake module of an air intake tract of an internal combustion engine is provided with an intake housing part that has at least one inlet for combustion air to be filtered and an outlet section. A filter housing part with an air filter element that filters the combustion air is provided. The filter housing part has an inlet section and at least one outlet for the filtered combustion air. An air connection between the outlet section of the intake housing part and an inflow side of the air filter element is provided. A fixed intake pipe part is arranged between the outlet section of the intake housing part and the inlet section of the filter housing part. The fixed intake pipe part at least partially forms the air connection between the outlet section of the intake housing part and the inflow side of the air filter element.

First claim

What is claimed is:

1. An intake module of an air intake tract of an internal combustion engine of a motor vehicle, the intake module comprising:
an intake housing part comprising
an inlet section and an outlet section;
at least one inlet opening for combustion air to be filtered to enter the inlet section of the intake housing part;
an inlet grid arranged in the at least one inlet opening of the intake housing part;
wherein the outlet section is arranged at an opposite second end of the intake housing part relative to the inlet section;
a plurality of water separating surfaces formed on circumferential housing walls of the intake housing part, the plurality of water separating surfaces each elongated horizontally in a direction from the inlet grid to the outlet section of the intake housing part, the plurality of water separating surfaces extending parallel to each other, the plurality of water separating surfaces each having a first end positioned at the inlet grid, and terminating at the opposite second end of the inlet section of the intake housing part;
the plurality of water separating surfaces providing an enlarged surface area that is active for water separation;
and
a water drain outlet opening arranged in a bottom wall of the intake housing part below the plurality of water separating surfaces;

a filter housing part comprising
an air filter element configured to filtrate the combustion air,
the filter housing part further comprising an inlet section and
further comprising at least one outlet for the filtered combustion air;

an air connection disposed between the outlet section of the intake housing part and an inflow side of the air filter element;
a fixed intake pipe part arranged between the outlet section of the intake housing part and the inlet section of the filter housing part,
wherein the fixed intake pipe part at least partially forms the air connection between the outlet section of the intake housing part and the inflow side of the air filter element.

2. The intake module according to claim 1 , wherein
the filter housing part and the intake housing part are arranged so as to be displaced relative to each other.

3. The intake module according to claim 1 , wherein
a flow cross-section provided in the intake housing part decreases in a main flow direction of the combustion air.

4. The intake module according to claim 1 , further comprising
at least one water separating device arranged upstream of the inflow side of the air filter element.

5. The intake module according to claim 1 , further comprising
at least one water separating surface arranged in the intake housing part.

6. The intake module according to claim 1 , further comprising
at least one water separating surface arranged in the intake pipe part.

7. The intake module according to claim 1 , further comprising
at least one particle separating device arranged fluidically between the at least one inlet of the intake housing part and the inflow side of the air filter element.

8. The intake module according to claim 1 , further comprising
at least one drainage device configured to drain media separated from the combustion air,
wherein the at least one drainage device is arranged between the inlet of the intake housing part and the inflow side of the air filter element.

9. The intake module according to claim 1 , wherein
the filter housing part and the intake housing part are flat.

10. The intake module according to claim 1 , wherein
the filter housing part is flat.

11. The intake module according to claim 1 , wherein
the intake housing part is flat.
