Apparatus for supplying a mixture of oxidizer and fuel to an internal-combustion engine includes a frame supporting oxidizer supply lines and fuel supply lines, the frame being mounted above an intake manifold and below the engine's carburetor. Discharge ports in the oxidizer and fuel supply lines are positioned so that a high-velocity flow of oxidizer entrains and atomizes a stream of fuel from an adjacent fuel-discharge port; each oxidizer port is aimed toward the mouth of a passage in the intake manifold so the stream of mixed oxidizer and fuel is directed into the passage without reducing the level of vacuum in the intake manifold plenum and so that the stream of oxidizer and fuel urges increased amounts of fuel-air mixture from the carburetor into the passage.
