INTERNAL COMBUSTION ENGINE ELECTROMAGNETIC NOZZLE Russian patent published in 1999 - IPC

FIELD: mechanical engineering; fuel systems of engines with carburation. SUBSTANCE: nozzle has core with fuel feed channel, magnetically conducting and limiting washers with fuel passage slots, valve member with fuel inlet channel and support seat with fuel outlet channel. With current supplied to electromagnetic winding, electromagnetic flux is formed which provides attraction of valve member to core, thus opening support seat fuel outlet channel. With valve member attracted to core fuel is delivered to electromagnetic nozzle outlet. Amount of fuel delivered by nozzle depends on time during which nozzle remains open. EFFECT: increased speed of action of electromagnetic nozzle owing to decrease in length of working stroke of valve member. 3 dwg
