Abstract

A motor vehicle has an engine compartment which can be closed by at least one hood, and in which there is an air intake line that can be indirectly or directly fluidically connected to an intake manifold of an internal combustion engine. The air intake line includes a fiber composite element made of an air-permeable fiber composite material.

First claim

What is claimed is:

1. A motor vehicle, comprising:
a hood for closing an engine compartment of the motor vehicle, said hood having a deformation region for pedestrian protection;
an air intake line arranged in the deformation region of the hood and having an inlet opening and an outlet opening, said air intake line being fluidly connected to an intake manifold of an internal combustion engine via an air filter, said air intake line comprising a fiber composite element made of an air-permeable fiber composite material which has a matrix made of thermoplastic material, said fiber composite element being configured to permit air flow through the fiber composite element into an air-conducting internal space of the air intake line along the air intake line, and out of the outlet opening also in case of blockage of the inlet opening; and
a sealing arranged on the inlet opening or the outlet opening and fastened to the fiber composite element.

2. The motor vehicle of claim 1 , wherein the fiber composite element has an inner coating on a side which faces the air-conducting internal space of the air intake line and/or an outer coating on a side which faces away from the internal space.

3. The motor vehicle of claim 2 , wherein the inner coating and/or the outer coating is configured as a film.

4. The motor vehicle of claim 1 , wherein the fiber composite element is configured as a core of a fiber composite arrangement.

5. The motor vehicle of claim 1 , wherein the air intake line is fastened on the hood.

6. The motor vehicle of claim 1 , further comprising at least one damping element for fastening the air intake line.

7. The motor vehicle of claim 1 , wherein at least portions of the air intake line are integrated in the hood.

8. The motor vehicle of claim 1 , wherein the hood has a support structure and an outer panel arranged on the support structure, wherein at least portions of the air intake line are arranged in the support structure.

9. The motor vehicle of claim 8 , wherein the air intake line is formed by the outer panel and/or an attachment of the hood.
