Abstract

L'invention concerne un processus (10) et un appareil (50) pour générer un carburant enrichi en oxygène pour un moteur à combustion interne. De l'eau du robinet est adoucie par des sels industriels dans une chambre d'adoucissement d'eau (55), puis passe dans une chambre de solution (60) et ensuite dans une chambre d'électrolyse (65). Dans la chambre d'électrolyse (65), la solution d'eau est décomposée en molécules d'hydrogène et d'oxygène par l'application d'un courant continu à pulsations. Les molécules d'hydrogène générées sont purifiées et stockées dans un collecteur d'hydrogène (75). Les molécules d'oxygène dissociées sont saturées et remises en circulation avec la solution d'eau provenant de la chambre d'électrolyse vers la chambre de solution (60). Un carburant fossile primaire provenant du réservoir de carburant d'un véhicule est envoyé vers un cylindre de moussage où il passe à travers un tube perforé (81) afin de créer des turbulences. Ensuite, le carburant moussé est mélangé à l'hydrogène pur recueilli dans un cylindre de mélange (80), formant ainsi un carburant saturé en hydrogène. Le carburant enrichi en hydrogène peut être acheminé directement vers un moteur à combustion interne, ou être stocké avant d'être acheminé.
