Abstract
Official abstract text for this publication.
The present invention concerns an assembly ( 1 ) comprising: an intake duct ( 4 ) extending between an air inlet ( 11 ) and a heat engine ( 2 ), a heat engine ( 2 ), an electric compressor ( 5 ) disposed on the intake duct and upstream from the heat engine ( 2 ), the electric compressor ( 5 ) being configured to allow the spark advance to be degraded during a transitory phase.
First claim
Opening claim text (preview).
1 . An assembly comprising: an intake duct extending between an air intake and a heat engine; the heat engine; and an electric compressor disposed on the intake duct upstream from the heat engine; the electric compressor being configured so as to enable the spark advance to be degraded during a transitory phase. 2 . The assembly as claimed in claim 1 , comprising at least one valve disposed upstream from the heat engine and downstream from the electric compressor and regulating the flow of intake air in the heat engine. 3 . The assembly as claimed in claim 1 , wherein the electric compressor is integrated into a bypass circuit comprising bypass means configured to conduct the intake air through the electric compressor during a transitory phase. 4 . The assembly as claimed in claim 1 , comprising a heat exchanger disposed on the intake duct. 5 . The assembly as claimed in claim 4 , wherein the electric compressor is disposed upstream from the heat exchanger and upstream from the valve. 6 . The assembly as claimed in claim 4 , wherein the electric compressor and the valve are disposed upstream from the heat exchanger. 7 . The assembly as claimed in claim 1 , wherein the electric compressor is equipped with a variable reluctance motor. 8 . A method for controlling an assembly as claimed in claim 1 comprising, during a transitory phase: a stage in which the electric compressor is activated; a stage in which intake air is circulated through the electric compressor; a spark advance degradation stage. 9 . The method as set forth in claim 8 , comprising a stage in which the intake airflow is regulated with a valve. 10 . A use of the assembly as claimed in claim 1 , for degrading the spark advance during a transitory phase. 11 . The use of the assembly as claimed in claim 10 , the transitory phase being a start-up phase.
