Patent

CA 2675005

In an automotive vehicle in which an air duct which forms an air guide passage for guiding air that has flowed into an engine compartment to an induction system of an internal combustion engine is provided integrally on an inner surface of a bonnet, a reduction in size and weight of the air duct and a compact disposition of the air duct within the engine compartment are attempted to be realized. An automotive vehicle includes an internal combustion engine 20 which is disposed within an engine compartment and an air duct 40 which is provided integrally on an inner surface of a bonnet 10. The air duct 40 forms an air guide passage 60 for guiding air that has flowed into the engine compartment to an induction system 20i of the internal combustion engine 20 between itself and a bonnet portion 30 which constitutes part of the bonnet 10 in cooperation with the bonnet portion 30. Because of this, the air duct 40 is a duct having an open section in which an edge portion 44 which is brought into abutment with the bonnet portion 30 in such a state that the air duct 40 is attached in place forms an opening along the air guide passage 60.

L'invention concerne une automobile ayant un conduit d'air formé d'un seul tenant avec la surface interne d'un capot et forme un trajet de guidage d'air pour guider l'air, qui circule dans un compartiment moteur, vers un dispositif d'admission d'air d'un moteur à combustion interne. Le conduit d'air a une dimension et un poids réduits et est installé de façon compacte dans le compartiment moteur. L'automobile a un moteur à combustion interne (20) placé dans le compartiment moteur et a également un conduit d'air (40) disposé d'un seul tenant avec la surface interne d'un capot (10). Le conduit d'air (40) forme, en coopération avec une partie de capot (30) qui fait partie du capot (10), un trajet de guidage d'air (60) entre le conduit d'air (40) et la partie de capot (30). Le trajet de guidage d'air (60) guide l'air dans le compartiment moteur vers le dispositif d'admission d'air (20i) du moteur à combustion interne (20). Le conduit d'air (40) a, dans son état installé, une section transversale ouverte où une bordure (44), qui est en contact avec la partie du capot (30), forme une ouverture s'étendant le long du trajet de guidage d'air (60).
