In the main nozzle of the carburetor of gasoline engine, the bleed air is let into the fuel stream, in general. This report handles about the basic problem of the mixing of this air and fuel, that is, the pressure drop caused by the mixing. This pressure drop is larger than that by the main jet. Applying the principle of momentum to the mixing, then [numerical formula] An Experiment is made with the simple model, twice size of prototype, using water in stead of gasoline, and the result shows that if N is small, α=1〜2, should be put in formula (1) and that if N is large, then should be applied, α=7〜30. In the case of bubble flow, N is small, while in the case of annular flow, N is large.
