Title (EN) ENGINE ASSEMBLY COMPRISING A TURBOCHARGER AND AN ELECTRICAL SUPERCHARGER
(FR) ENSEMBLE MOTEUR COMPORTANT UN TURBOCOMPRESSEUR ET UN COMPRESSEUR ELECTRIQUE DE SURALIMENTATION
Abstract:
(EN) The invention relates to an engine assembly (1) comprising at least one gas intake line (10) supplying an engine block (4) of an internal combustion engine (2) and a gas exhaust line (14) at the outlet of the engine block, a turbocharger (16) allowing the pressure of the gases flowing through the intake line (10) to be raised, said turbocharger being provided with a device (200) for regulating the pressure upstream of the turbine of the turbocharger. The engine assembly comprises an electrical supercharger (26) arranged on the gas intake line (10) and a device (30) for controlling the electrical supercharger (26). The control device (30) is designed to receive information relating to the activation of the pressure-regulating device (200) and to control the electrical supercharger (26) according to said information and complementary information about a supercharging deficit of the internal combustion engine (2).
(FR) L'invention concerne un ensemble moteur (1), comprenant au moins une conduite d'admission (10) de gaz alimentant un bloc-moteur (4) d'un moteur à combustion interne (2) et une conduite d'échappement (14) des gaz en sortie du bloc-moteur, un turbocompresseur (16) permettant d'élever la pression des gaz s'écoulant dans la conduite d'admission (10), ledit turbocompresseur étant équipé d'un dispositif de réglage (200) de la pression en amont de la turbine du turbocompresseur. L'ensemble moteur comporte un compresseur électrique (26) de suralimentation agencé sur la conduite d'admission (10) de gaz et un dispositif de commande (30) du compresseur électrique (26) de suralimentation. Le dispositif de commande (30) est configuré pour recevoir des informations relatives à l'activation du dispositif de réglage (200) de la pression et pour commander le compresseur électrique (26) de suralimentation en fonction desdites informations et d'une information complémentaire de déficit de suralimentation du moteur à combustion interne (2).
