DEVICE FOR MAGNETIC MODIFICATION OF FUEL IN INTERNAL COMBUSTION ENGINE Russian patent published in 2005 - IPC

FIELD: mechanical engineering; internal combustion engines.

SUBSTANCE: invention relates to devices for magnetic modification of fuel in internal combustion engine. Proposed device makes it possible to modify fuel by magnetic field owing to additional action of magnetic field when fuel passes through peripheral fuel modification chamber along outer cylindrical surface of permanent magnet. Device contains cylindrical housing, cover, inlet and outlet fuel unions with inlet and outlet channels, magnetic system formed by circular permanent magnets arranged in housing coaxially, one after the other with clearance, with like poles pointed to each other, and with centering insert. Each permanent magnet is located between inlet shell with cylindrical projection and outlet shell with inner hole. Magnetic system is provided with central fuel modification chamber, for fuel passing along inlet channel of inlet fuel union through number of holes of inlet shell equidistant from axis of device, end face fuel swirler chamber formed in outlet shell and communicating with central fuel modification chamber, intermediate chamber formed by conical surfaces made, respectively, on end face of cylindrical projection of inlet shell and on outlet shell, inlet chamber placing inlet channel in communication with number of holes in inlet shell. Housing, cover and centering insert are made on nonmagnetic material. Inlet and outlet shells are made of ferromagnetic material. Device is furnished with peripheral fuel modification chamber, central channel, bypass channels, ring clearance, centering splines, distance bushing and sealing gasket. Fuel modification peripheral chamber is located between outer cylindrical surface of permanent magnet and part of inner cylindrical surface of housing, being placed in communication with end face fuel swirler chamber through bypass channels and with central channel through ring clearance. Central channel is made in inlet shell and it communicates with intermediate chamber. Centering splines are made on cylindrical projection of inlet shell and they are in contact with inner surface of centering insert. Distance bushing is located in clearance. Sealing gasket is placed between cylindrical projection of inlet shell and outlet shell, being made of any elastic fuel resistant material.

EFFECT: provision of complete combustion of fuel, improved economy, reduced content of harmful substance in exhaust gases.
