Abstract

La présente invention concerne un dispositif d'admission à réduction de bruit pour augmenter la sortie d'un moteur à combustion interne et, plus spécifiquement, un dispositif d'admission à réduction de bruit, pour augmenter la sortie d'un moteur à combustion interne, qui est disposé sur une unité d'admission d'un moteur à combustion interne d'un véhicule ou similaire, est pourvu d'un générateur de vortex d'air et améliore le flux d'air au moyen de la rotation de l'air qui est aspiré ou évacué dans un tourbillon rotatif, et améliore ainsi l'efficacité de combustion au moyen d'une sortie améliorée en fonction de l'efficacité d'admission/échappement et augmente ainsi l'efficacité du carburant, réduit le bruit dû à la séparation d'écoulement, réduit la fumée et prolonge la durée de vie d'un moteur. Le dispositif d'admission à réduction de bruit pour augmenter la sortie d'un moteur à combustion interne comprend un tuyau intérieur (12), ayant un creux (13), à l'intérieur d'un tuyau cylindrique (11) disposé entre l'extérieur du moteur à combustion interne et le moteur, a, à des intervalles fixes, 3 à 6 pales de vortex (15) formé de manière inclinée de manière à avoir une forme de spirale dans une direction dans un espace (14) entre le tuyau cylindrique (11) et le tuyau interne (12), et permet ainsi à l'air d'être fourni dans une direction et de former un tourbillon. Les pales de tourbillon (15) ont des motifs ondulés formés en continu sur la partie d'entrée avec laquelle l'air aspiré entre en contact au départ. Les motifs ondulés ont des parties incurvées (16, 16a, 16b), formées de manière concave et convexe sous la forme d'une courbe semi-circulaire ou d'une courbe elliptique, ce qui réduit la séparation des flux et facilite l'écoulement de l'air.
