An intake system for a multicylinder internal combustion engine includes a manifold having inlet runners for conducting charge air into the cylinders of an engine, and at least one secondary throttle valve situated within at least one of the inlet runners. An electrically driven motor positions the secondary throttle valve, with the motor being operated by a controller, which senses engine operating parameters including the temperature of an electrically driven motor which powers the secondary throttle valve.

Cette invention concerne un circuit d'admission de moteur à combustion interne multi-cylindres comportant un collecteur d'admission à canaux multiples d'injection d'air dans les cylindres et au moins un papillon d'admission secondaire dans au moins un des canaux d'injection d'air. Un moteur électrique sert à positionner le clapet du papillon d'admission selon les signaux de commande reçus d'un contrôleur qui suit les paramètres de fonctionnement du moteur thermique, y compris la température d'un moteur électrique qui commande le papillon d'admission secondaire.
