Title (EN) SNOWMOBILE INDUCTION SYSTEM
(FR) SYSTEME D'ADMISSION D'UNE MOTONEIGE
Abstract:
(EN) A snowmobile is provided including an internal combustion engine (20), an induction system (82) communicating with the engine (20), and a body (14) defining an engine compartment in which the engine (20) is at least in part contained. The body of the snowmobile includes at least two openings (120) which communicate with the induction system, and a door (140) movably positioned at at least one of the openings. The door is adapted to selectively open and close the opening to regulate a flow of induction air through the opening.
(FR) L'invention concerne une motoneige comprenant un moteur à combustion interne (20), un système d'admission (82) communicant avec le moteur (20), et un corps (14) définissant un compartiment moteur dans lequel le moteur (20) est au moins partiellement contenu. Le corps de la motoneige comprend au moins deux ouvertures (120) communiquant avec le système d'admission, et une porte (140) placée de manière mobile au niveau d'au moins une des ouvertures. La porte est conçue pour ouvrir et fermer de manière sélective l'ouverture afin de réguler le débit d'air d'admission à travers l'ouverture.
