FUEL MIXTURE HOMOGENIZING DEVICE (VERSIONS) Russian patent published in 2003 - IPC

FIELD: mechanical engineering; engines. SUBSTANCE: proposed fuel mixture homogenizing device contains perforated homogenizing member coupled with ultrasonic converter and placed before intake manifold and coaxially with corresponding section of channel of pipeline in internal combustion engine fuel system. Homogenizing member is made in form of hollow cone whose vertex is pointed to side of intake manifold. Plate- gate is arranged on outer surface of cone opposite to each perforation hole, one of end plate-gate being rigidly secured on cone. Said plate-gate is made of flexibly deformable material with mass and rigidly in direction square to its surface providing vibration of free end under action of elastic vibrations excited ion cone by ultrasonic converter. Said ultrasonic converter is installed outside fuel system pipeline and is provided with needle vibrator whose end is rigidly connected with cone. Design of other version is laid in description of device. Invention provides high homogeneity and degree of dispersion of fuel and uniform distribution of fuel in section of channel of engine fuel system. EFFECT: improved efficiency of engine in operation. 3 cl, 7 dwg
