Abstract

L'invention concerne l'alimentation en mélange précompressé des cylindres d'un moteur à combustion interne, deux temps. Selon un mode de réalisation la précompression du mélange explosif pris au carburateur est réalisé au moyen d'un cylindre auxiliaire CH du moteur, communiquant par un canal T avec les cylindres principaux C1, C2 à travers des soupapes V1, V2. Le piston du cylindre auxiliaire est entraîné par un arbre secondaire A' à une vitesse deux fois plus grande que celle de l'arbre principal A par l'intermédiaire d'engrenages N, N'. En variante il est prévu comme moyen de précompression du mélange un compresseur à piston rotatif type Wankel, ou une pompe alimentant une chambre réservoir. Application à la réalisation de moteurs deux temps de poids et de prix réduit.
