FUEL SUPPLY DEVICE AND VEHICLE WITH THE SAME
Document Type and Number:
WIPO Patent Application WO/2005/045237
Kind Code:
A1
Abstract:
An air funnel (8) is connected to a throttle body (7) via a joint member (6’). The air funnel (8) has a tapered shape with the suction side having a slightly larger diameter. On a suction opening of the air funnel (8) is a separation layer-inducing section (8a) formed by bending the peripheral edge outward in an arc shape. The separation layer-inducing section (8a) is formed in an arc shape having a curvature radius r of approximately 0.33 to 0.01 X D, with D being the diameter of the suction opening of the air funnel (8). This causes a separation layer (a) with a negative pressure to be produced on the inner surface near the suction opening, and fuel blows back is collected by the separation layer (a).
