Abstract

A motor vehicle has a supercharged internal combustion engine arranged at the rear and can be fed cooled combustion air via a charge air cooler ( 7 ). The charge air cooler ( 7 ) is positioned above the internal combustion engine below a covering hood ( 4 ) for the internal combustion engine. The charge air (B EIN ) is fed via at least one charge air inlet opening in a charge air inlet shaft ( 8 ) that adjoins the covering hood ( 4 ) and is discharged via at least one charge air outlet shaft (B AUS ) that is connected to outlet openings ( 13, 14 ) in the region of a license plate recess ( 9 ) of the motor vehicle.

First claim

What is claimed is:

1 . A motor vehicle comprising: a supercharged internal combustion engine arranged at a rear end of the motor vehicle; and a charge air cooler for feeding cooled combustion air to the internal combustion engine, the charge air cooler being positioned above the internal combustion engine below a covering hood for the internal combustion engine, at least one charge air inlet opening in a charge air inlet shaft that adjoins the covering hood for feeding the charge air (B EIN ) and at least one charge air outlet shaft which is connected to outlet openings in license plate recess of the motor vehicle for discharging the air (B AUS ) from the charge air cooler.

2 . The motor vehicle of claim 1 , wherein the charge air inlet shaft and the charge air inlet openings extend substantially over an entire width of the covering hood.

3 . The motor vehicle of claim 1 , wherein the charge air inlet shaft and the charge air inlet openings are arranged in the rear-side air flow region of a rear spoiler that is arranged on the covering hood.

4 . The motor vehicle of claim 3 , wherein the charge air inlet shaft defines a connection between the covering hood and the internal combustion engine.

5 . The motor vehicle of claim 3 , wherein the charge air feed to the charge air cooler is controlled set via an adjustable rear spoiler.

6 . The motor vehicle of claim 1 , wherein the charge air outlet openings are integrated into the license plate recess to create an annular diffuser effect that increases the charge air throughput.

7 . The motor vehicle of claim 6 , wherein the charge air outlet openings are arranged to reach partially around the motor vehicle license plate in the lateral region of the license plate recess.

8 . The motor vehicle of claim 1 , wherein the license plate recess is formed in the covering hood for the internal combustion engine.

9 . The motor vehicle of claim 1 , wherein the license plate recess is formed in a rear-side termination of the motor vehicle.
