Abstract

The present invention relates to an assembly ( 1 ) for a combustion engine ( 10 ) comprising an electric compressor ( 5 ) and an air intake system, the air intake system comprising a double manifold ( 2 ) at the inlet to which there is a valve ( 4 ) configured to allow the intake gases to circulate in the manifold ( 2 ) and/or to allow the intake gases to bypass the electric compressor ( 5 ). The double manifold ( 2 ) comprises a swirl manifold ( 22 ) and a filling manifold ( 21 ), fed by two independent inlets, which can be closed off by the valve ( 4 ) independently of one another.

First claim

1 . An assembly for a combustion engine comprising:
an electric compressor; and an air intake system comprising a double manifold at the inlet to which there is a valve configured to allow the intake gases to circulate in the manifold and/or to allow the intake gases to bypass the electric compressor.

2 . The assembly for a combustion engine according to claim 1 , wherein the double manifold comprises a swirl manifold and a filler manifold, fed by two independent inlets, which are closed off by the valve independently of one another.

3 . The assembly for a combustion engine according to claim 1 , comprising a pipe bypassing the electric compressor, which is closed off by the valve when the electric compressor is activated.

4 . The assembly for a combustion engine according to claim 1 , wherein the engine's main air intake pipe divides into a first pipe and a bypass pipe that are independent and open out into the valve.

5 . The assembly for a combustion engine according to claim 4 , wherein the electric compressor is arranged on the first pipe upstream of the valve.

6 . The assembly for a combustion engine according to claim 4 , wherein the first pipe is arranged so that, at a given position of the valve the first pipe is the only pipe in communication with the filler and swirl pipes of the manifolds.

7 . A method of using an assembly according to claim 1 , comprising:
non-activation of the electric compressor; bypassing the electric compressor by circulating the gases in the bypass pipe; and feeding the swirl pipe.

8 . A method of using an assembly according to claim 1 , comprising:
non-activation of the electric compressor; bypassing the electric compressor by circulating the gases in the bypass pipe; and feeding the swirl pipe and manifold pipe.

9 . A method of using an assembly according to claim 1 , comprising:
activation of the electric compressor; circulating the gases in the first intake pipe, via the electric compressor; and feeding the swirl pipe and manifold pipe.

10 . The method of claim 7 , wherein the method is performed in order to prevent any circulation of fluid in a double manifold.
