ABSTRACT:
A nitrous oxide nozzle for inserting a mixture of oxidizer and fuel into a passage of an engine's intake manifold has two inlet ports, each of which communicate with a conduit. A nitrous oxide conduit vents into the apex of a bell-shaped emitter, and a fuel conduit vents into a side portion of an atomizing cavity adjacent the emitter, so that high-pressure nitrous oxide gas flowing through the emitter entrains fuel flowing through the fuel conduit, then atomizes the fuel and mixes with the fuel. The bell shape of the emitter provides improved mixing of fuel with the nitrous oxide; the discharged fuel/oxidizer mixture from the emitter is introduced into air flowing through an engine's intake manifold, and is conveyed to a cylinder for burning.
