Abstract

L'invention concerne un appareil pour la génération d'énergie au moyen de la chaleur provenant à la fois de l'eau de refroidissement et des gaz d'échappement de moteurs à combustion interne. Ledit appareil est conçu pour acheminer l'eau de refroidissement de haute température de la chemise d'eau d'un moteur jusqu'à une chaudière, par un tuyau de décharge d'eau de refroidissement, et pour chauffer l'eau au moyen de la chaleur des gaz d'échappement déchargés de la chambre de combustion du moteur. Ledit appareil génère ainsi d'abord de la vapeur chaude sous pression dans la chaudière, puis actionne une turbine au moyen de la vapeur, de sorte que de l'énergie utilisable en tant que source d'énergie pour des pièces d'entraînement additionnelles soit produite. Dans ce cas, les gaz d'échappement chauds provenant du cylindre s'écoulent dans la chaudière en passant par un tuyau chauffant. Les gaz d'échappement sont finalement évacués de la chaudière dans l'atmosphère. Une fois la vapeur traitée dans la turbine, elle se transforme en eau condensée qui est récupérée par la chemise d'eau du moteur, par un tuyau d'amenée d'eau. L'appareil de l'invention permet d'améliorer l'efficacité thermique du moteur, d'économiser du carburant et d'empêcher efficacement la pollution de l'environnement par les gaz d'échappement. Ledit appareil est également utilisé efficacement avec des moteurs d'automobile, des moteurs de locomotives, des générateurs, des moteurs marins et une grande diversité de moteurs industriels.
