    "publication_year": null,
    "device_name": "Fuel Mixture Engine",
    "goal": "Reduce hydrocarbon consumption and pollutant emissions by using a water-rich fuel mixture that can be ignited and combusted in conventional internal-combustion engines.",
    "problem_addressed": "High fuel consumption and emissions (NOx, CO_2) from standard gasoline or diesel engines.",
    "concept_summary": "Water is conditioned and polarized by electromagnetic and ultrasonic processes, then mixed with a small fraction (~=10 %) of gasoline or diesel. The mixture undergoes cavitation and partial electro-decomposition, forming a fine foam that ignites readily. The foam-like fuel is fed to a combustion chamber (e.g., Wankel rotary engine, turbine, or burner) where it burns with high efficiency and minimal pollutants.",
    "detailed_description": "The patented system comprises a reaction chamber equipped with an ultrasonic oscillator and a mechanical cavitation disc. Water, low-nitrogen air (often oxygen-enriched), and a hydrocarbon fuel are introduced. Ultrasonic energy and cavitation cause partial breakdown of water molecules, producing reactive hydrogen radicals that enhance combustion. The mixture is homogenized into a foam, which is then metered by a micro-processor-controlled valve to the engine. A control arrangement synchronizes mixing, cavitation, and ignition to achieve optimal nucleation and exhaust composition. Prototypes have been demonstrated (1994 DVS congress film) showing operation with 90 % water and 10 % diesel, claiming virtually pollutant-free combustion.",
