Abstract

La présente invention concerne un dispositif pour améliorer les performances et iefonctionnement de moteurs à combustion interne par aspirationaérodynamique et mécaniquedes gaz brûlés au niveau de ia canalisation d'échappement. Lemoteur (m) comporte, selon l'invention, un dispositif d'aspiration aérodynamique (a) à l‘intérieur de ia culasse, avec deuxcanaux d'échappement (3a) et (3b), qui réalise une aspiration des gazbrûlés (ec), par effet detrompe, et, un dispositif mécanique (b), al'extérieur de la culasse, qui est un assemblage<<turbo-compresseur-aspirateur» comportant deux roues (chaudes)(5) et (7) et une roue(froide) (6). Selon l'invention, le dispositif d'aspiration aérodynamique (a), et ia roue (chaude) aspiratrice (7) de l’assemblage mécanique (b) engendrent une dépression dans le canal d'échappement(3b). Les gaz brûlés (ec) s'évacuent librement du cylindre (1), sans résistance de la contre-pression.
