Abstract

La présente invention concerne une automobile, et plus particulièrement, un panneau de protection inférieur pour décharger de manière efficace l'air qui est introduit dans un compartiment moteur et concerne aussi une automobile équipée de celui-ci. Le panneau de protection inférieur pour l'automobile qui recouvre la partie inférieure du compartiment moteur de l'automobile comporte un corps ayant une forme lui permettant d'être monté sur la partie inférieure du compartiment moteur de l'automobile, des ouvertures de décharge d'air étant formées sur le corps. Une surface, parmi les deux surfaces qui sont positionnées le long de la direction de l'écoulement d'air passant au travers de la partie inférieure de l'automobile et qui constituent les surfaces formant les ouvertures de décharge d'air, est formée avec une inclinaison dans la direction de l'air.
