FUEL-INJECTION NOZZLE Russian patent published in 2002 - IPC

FIELD: means of fuel feed and atomization. SUBSTANCE: the nozzle has a branch pipe that feeds fuel to the atomizer, and a vibration system, which is made in the form of a magneto-impulse device consisting of a winding located on the outer side of the branch pipe and connected to an electric pulse generator. When the pulse generator is switched on and current of a large amplitude passes in the winding, a high-power pulse of a magnetic field is produced around it, which induces in the branch pipe an eddy current pulse, whose magnetic field acts toward the external magnetic field set up by the winding. As a result of interaction of the magnetic fields, electromagnetic forces arise that are directed perpendicularly to the vector of magnetic induction, i. e. a pressure on the branch pipe surface is produced that is transferred to the fuel in it. EFFECT: enhanced efficiency of atomization and simplified construction, as well as expanded functional potentialities. 1 dwg
