The present invention provides a system for providing hydrogen gas to inject into the intake of an internal combustion engine. A hydrogen storage reservoir in communication with the gas output port stores a supply of hydrogen, and a hydrogen storage release valve retains the hydrogen in the storage reservoir and selectively releases hydrogen from the storage reservoir when the engine is started. In the preferred embodiment the system comprises an electrolysis cell that produces hydrogen when the engine is warm, and hydrogen is released from the storage reservoir when the system is active but the electrolysis cell is not producing hydrogen.

La présente invention concerne un système d'amenée de gaz hydrogène en vue de son injection dans l'admission d'un moteur à combustion interne. Un réservoir de stockage d'hydrogène en communication avec l'orifice de sortie de gaz emmagasine une réserve d'hydrogène et une vanne de décharge de stockage d'hydrogène retient l'hydrogène dans le réservoir de stockage et libère sélectivement de l'hydrogène du réservoir de stockage lors du démarrage du moteur. Dans le mode de réalisation préféré, le système comporte une cellule d'électrolyse qui produit de l'hydrogène lorsque le moteur est chaud, de l'hydrogène étant libéré du réservoir de stockage lorsque le système est actif mais que la cellule d'électrolyse ne produit pas d'hydrogène.
