Abstract

a. Procédé et dispositif pour l'exploitation d'un moteur à combustion interne à compression d'air et à auto-allumage pour carburants liquides. b. Procédé caractérisé en ce que du carburant contenant de l'oxygène et s'allumant difficilement est injecté dans la chambre de combustion en forme d'auge 4 par un premier moyen d'injection 2, et que grâce à un second moyen d'injection 3, du carburant facile à allumer, par exemple du gas-oil, est injecté dans la chambre de combustion en forme d'auge 4 pour démarrer et/ou pour entretenir la combustion, les temps d'injection du carburant facile à allumer et du carburant contenant de l'oxygène difficile à allumer empiétant l'un sur l'autre. c. L'invention s'applique notamment aux moteurs Diesel d'automobiles.
