Abstract

Un moteur multimode programmable à conservation d'énergie destiné notamment aux importants besoins de puissance de chargeurs de marchandises et de centrales électriques, comprend un moteur Diesel à deux temps modifié de façon à fonctionner en un mode choisi entre cinq modes programmables possibles; 1) un mode de combustible fossile, 2) un mode d'injection d'air comprimé surchauffé/d'eau surchauffée, 3) un mode d'injection de vapeur comprimée surchauffée/d'eau surchauffée, 4) un mode d'injection de gaz comprimé surchauffé/d'eau surchauffée, (5) un mode d'injection de gaz surchauffé comprimé et sélectionné par filtre/d'eau surchauffée. L'énergie perdue, provenant de la chaleur émanant de la combustion du combustible fossile, lorsque le moteur fonctionne en mode de combustible fossile initial, est utilisée dans une série d'échangeurs thermiques à contre-courant dont la température et la pression sont surveillées et qui comprennent des soupapes permettant la commande par ordinateur de vitesses de transfert thermique, ce qui permet d'obtenir de l'eau surchauffée à la température et à la pression requises pour les autres modes de fonctionnement choisis du moteur. L'ordinateur applique par défaut le mode (1) de fonctionnement du moteur à combustible fossile, lorsque les conditions de sélection de mode et d'eau surchauffée requises ne sont pas définies dans les échangeurs thermique à contre-courant.
