Abstract: An injection gate (44,144,244,344) for high pressure, high velocity secondary fluid for admixture of an atomized spray (80,180) thereof with another or primary fluid that atomizes the other fluid. The secondary fluid may be an accelerant and the primary fluid may be a low pressure fuel/air mixture in a fuel injection arrangement for an internal combustion engine. An injection billet (10,110,210,310) for an engine is interposed between the carburetor (12) and the manifold (14), with an array of such injection gates (44,244,344) paired with an array of fuel/air gates (34,234,334) about an aperture coinciding with a throttle bore (60,160,260,360) and evenly balancing the spray about the throttle bore, creating a halo effect of atomized admixture of accelerant/fuel. The injection of accelerant is directed sharply downwardly toward the center of the bore and through the injected fuel stream, atomizing the fuel thereof for a high efficiency boost of horsepower.
