Applicant:

BIOACTIVOS Y NUTRACEUTICOS DE MEXICO S A DE C V [MX]

Absstract of: WO2020130771A1

The present invention describes a hydrogen generating device for fuel savings which has the advantage of having an ultrasound generator (7) inside a water tank (6), said generator splitting water when put into operation, creating water vapour or microparticles, which is channelled into an electrolytic cell (1), said vapour being brought into contact with an anode (2) and a cathode (4), which separate the hydrogen and oxygen; where the fact that the water is present as a vapour or as microparticles means that the splitting thereof is more efficient and both the anode (2) and cathode (4) undergo less wear. The hydrogen is subsequently channelled into a combustion chamber of an internal combustion machine, where it maximises the burning of fuel, thereby reducing the use thereof, as a result of its detonant ability. Another advantage of the present invention is that the oxygen obtained in the electrolytic cell (1) is channelled into the water tank (6) by way of an oxygen pipe (10), where said oxygen increases the alkalinity of the water upon mixing with it, thereby favouring the separation of hydrogen and oxygen in the electrolytic cell (1).
