Abstract
Abstract A fuel-air homogenizing device for insertion between the carburetor and the intake manifold of an internal combustion engine. The device increases carburetion in the sense that the fuel-air mixture entering and passing through the same is thoroughly mixed or homogenized. The device contains at least one and preferably both of the following features; first, a whistle is laterally disposed through the device such that the sound emitting portion is disposed in the central aperture area of the device that communicates with the carburetor and the intake manifold conduit. Reduced pressure at the intake manifold is relied upon to draw air in from outside the carburetion system, this to supply the sound waves within and below the device to aid in the mixing of the fuel and air; second, a plurality of mutually spaced ribs having rounded surfaces and angulated downwardly are used as deflecting means so as to further insure improved homogenization. Filter means may be provided relative to the ambient air supply.
