    "device_name": "ZEFS Fuel Saver Device",
    "goal": "Increase internal combustion engine efficiency and reduce harmful emissions.",
    "problem_addressed": "High fuel consumption and NOX, CO, THC emissions from combustion engines.",
    "concept_summary": "The device uses specially oriented magnetic fluxes (and, in related patents, electric fields) to alter the molecular structure of hydrocarbon fuel, reducing its viscosity and improving atomization. This leads to a more complete burn, lower emissions and better fuel economy.",
    "detailed_description": "ZEFS devices are compact, non-moving units that attach to carburetors or fuel-injection systems. They generate complex magnetic flux orientations that break down fuel molecular clusters from ~760 um to ~140 um (carbureted) or ~3 um (injection). In a related patent (WO2014179217), a series of electrically charged plates creates a dielectrophoretic field that induces dipoles in paraffin and asphaltene molecules, causing them to aggregate into sub-micron clusters and thereby lowering bulk viscosity. Independent testing at the Hong Kong Exhaust Emissions Laboratory reported up to 95 % reduction in THC, 86 % reduction in NOX and 78 % reduction in CO for a motorcycle and generator.",
