Abstract

La présente invention relève de la construction des moteurs. Selon l'invention, dans le moteur à pistons qui comprend des cylindres de compresseur et de travail, on injecte de l'air au moyen d'un turbocompresseur via des robinets d'extraction dans les cylindres de travail pendant le temps d'échappement. Depuis le cylindre de compresseur, l'air est injecté en séquence dans des collecteurs à air sous pression puis dans les cylindres de travail via des soupapes d'admission pendant le temps d'échappement lors de la vidange des cylindres, on poursuit l'injection pendant les temps d'admission et de compression lors du remplissage des cylindres de travail et on la termine lorsque le piston du compresseur atteint le point mort haut.
