DEVICE FOR HOMOGENIZATION OF FUEL CHARGE IN INTERNAL COMBUSTION ENGINE Russian patent published in 1995 - IPC

FIELD: engine engineering. SUBSTANCE: device has screw blades interposed between central axis and wall of the inlet pipe line to define longitudinally-screw sector passages in the pipe line. Generatrices of the screw surface of the blades are arc- like. Pitches of adjacent screw surfaces are different. When air jets (or fuel mixture jets) flow through the passages they are set in rotation about the axis of the pipe line and take addition swirling at the arc-like blades. Moreover, the outlet velocity of the jets are different that leads to enhanced turbulization of the charge to be supplied to the cylinder. The device can be positioned immediately at the outlet valve. EFFECT: improved mixing. 2 cl, 5 dwg
