Fuel injector nozzle adapter

A nozzle for providing nitrous oxide to an internal combustion engine, the nozzle comprising:

• a fuel injector passage, having a central axis and terminating at an injector outlet, for passing fuel from a fuel injector therethrough;
• a first auxiliary passage, terminating at a first outlet, for passing nitrous oxide therethrough;
• a second auxiliary passage, terminating at a second outlet, for passing nitrous oxide or additional fuel therethrough;
• and
• wherein the first outlet and the second outlet comprise radial outlets.

A nozzle for providing nitrous oxide to an internal combustion engine, the nozzle comprising:

• a fuel injector passage, having a central axis and terminating at an injector outlet, for passing fuel from a fuel injector therethrough;
• a first auxiliary passage, terminating at a first outlet, for passing nitrous oxide therethrough;
• a second auxiliary passage, terminating at a second outlet, for passing nitrous oxide or additional fuel therethrough;
• and
• wherein the first outlet and the second outlet are on opposite sides of the fuel injector outlet.

A nozzle for providing nitrous oxide to an internal combustion engine, the nozzle comprising:

• a fuel injector passage, having a central axis and terminating at an injector outlet, for passing fuel from a fuel injector therethrough;
• a first auxiliary passage, terminating at a first outlet, for passing nitrous oxide therethrough;
• a second auxiliary passage, terminating at a second outlet, for passing nitrous oxide or additional fuel therethrough;
• and
• wherein the first outlet and the second outlet are located about 10 degrees to about 180 degrees apart relative to the central axis of the fuel injector passage.

A nozzle for providing combustion reactants to an internal combustion engine, said nozzle comprising:

• an interior cup having an injector inlet end and an outlet end opposed to the injector inlet end, the interior cup comprising:
• a fuel injector receptacle in the injector inlet end;
• a fuel injector passage, the fuel injector passage having a central axis and terminating at the outlet end;
• a first auxiliary input location;
• a plurality of first auxiliary passages arranged in an annular pattern around the central axis and radially outward of the fuel injector passage and extending from the first auxiliary input location to the outlet end;
• a first annular ring disposed around the interior cup proximal to the first auxiliary input location, the first annular ring comprising a first auxiliary input port;
• and
• a receptacle cup disposed around the interior cup proximal to the outlet end;
• wherein the fuel injector passage is adapted to pass fuel from a fuel injector to the outlet end, the first auxiliary input port is adapted to pass a first combustion reactant to the plurality of first auxiliary passages, and the plurality of first auxiliary passages are adapted to pass the first combustion reactant to the outlet end.
