FUEL TREATMENT PROCESS AND DEVICE Russian patent published in 2000 - IPC

FIELD: engine manufacture; internal-combustion engines, thermal devices, and the like. SUBSTANCE: fuel treatment includes separation of its flow into components and its repeated treatment with magnetic field near end surfaces of coaxially arranged annular permanent magnets. Fuel is pre-treated by magnetic field for which purpose it is displaced over helical line about annular magnets and its flow is separated into central and peripheral components in proportion of 20- 25 and 75-80 %; peripheral component of flow is exposed to magnetic field of utmost field strength and central component is repeatedly expanded and contracted as it is passed through hollow taper inserts ; then central and peripheral components are mixed up. Device implementing proposed process has cylindrical chamber, inlet and outlet pipe unions, three annular permanent magnets coaxially arranged inside chamber, fuel flow separator placed between magnets and provided with central bore and peripheral slits, three substrates installed in tandem within chamber and provided with central holes and peripheral slits, three expanding and one contracting hollow taper inserts; flow section area of flow separator central bore is smaller than total area of flow sections of its peripheral slits by three or four times. EFFECT: reduced toxicity of exhaust gases and improved fuel saving. 8 cl, 1 dwg
