Abstract: An electrolytic system for an internal combustion engine includes an electrolyte tank for receiving an anode electrode, a cathode electrode, and an electrolytic fluid therein for communication with the anode and cathode. A power source applies an electrical potential between the anode and the cathode to generate a current through the electrolytic fluid and produce an electrolytic reaction in the electrolyte tank which produces combustible gases. A gas outlet communicates the combustible gases from the electrolyte tank to the internal combustion engine. At least one of the electrodes A hollow passage which does not communicate with the electrolytic fluid in the electrolyte tank extends through one of the electrodes to receive a heat exchange fluid circulated therethrough so as to be arranged to exchange heat with said at least one of the electrodes.
