Abstract

L'invention porte sur un dispositif d'admission d'air pour un moteur de véhicule à moteur à deux roues, qui est conçu de telle sorte que le centre d'un capteur de papillon des gaz (18), le centre d'un capteur de température d'air d'admission (19) et le centre d'un capteur de pression d'air d'admission (20) sont disposés aux sommets d'un triangle (35) formé dans un boîtier de capteur (17) et placé en amont dans un passage d'admission d'air (2) par rapport à l'axe (Y) d'un arbre de vanne (5a). Dans le boîtier de capteur (17), le capteur de papillon des gaz (18), le capteur de température d'air d'admission (19) et le capteur de pression d'air d'admission (20) sont montés concentriquement en amont dans le passage d'admission d'air (2) par rapport à l'axe (Y) de l'arbre de vanne (5a). Cette configuration permet, en particulier indépendamment du capteur de pression d'air d'admission (19), de réduire la longueur axiale d'un corps de papillon des gaz (1) placé en aval dans le passage d'admission d'air (2) par rapport à l'arbre de vanne (5a). En conséquence, la dimension et le poids du corps de papillon des gaz (1) peuvent être réduits et, en même temps, la taille du boîtier de capteur (17) peut être réduite.
