    "concept_summary": "An on-board electrolytic cell (sealed ABS chamber) containing an aqueous KOH electrolyte produces a mixture of oxygen, hydrogen, steam, and structured water. The mixture is routed through a sealed duct to the engine air-intake, enriching the combustion charge and facilitating cracking of long-chain hydrocarbons. Safety features (burstable pressure-release section, pressure-release plug, vent valve) mitigate explosion risk.",

        "The electrolysis chamber is constructed at least in part of acrylonitrile butadiene styrene resin (ABS) because of its resistance to chemicals such as the electrolyte solution and its ability to withstand large temperature fluctuations without degradation.",
        "Preferably the electrolyte is KOH. Preferably there is provided a replenishing supply of the KOH.",
        "The method comprises ... using combustion of the oxygen and hydrogen in the combustion chamber with the hydrocarbon fuel in conjunction with the steam and structured water to effect cracking of unspent portions of the hydrocarbon fuel.",
        "In structured water, the water molecules form alternating negative and positive layers around a positively charged ion. This gives the water a pseudo-crystalline or solid structure, even at room temperature."
