Abstract

A fuel injector adapter for providing nitrous oxide to an internal combustion engine is disclosed. The nozzle has a central fuel injector passage that terminates at a first outlet end. Fuel from a fuel injector may be passed through the central fuel injector passage. The nozzle also has an inner annular passage arranged circumferentially around the central fuel injector passage. The inner annular passage terminates at a second outlet end. The nozzle also has an outer annular passage arranged circumferentially around the inner annular passage that terminates at a third outlet end. One or both of the inner and outer annular passages is adapted to pass nitrous oxide through it. The nozzle is adapted to fit between a fuel injector and an engine without substantial modification to the engine.

Claims

1. A nitrous oxide kit for an internal combustion engine for providing nitrous oxide through an engine'"'"'s original fuel injector receptacles, the nitrous oxide kit comprising:

one or more nozzles;

wherein each of the one or more nozzles is adapted to pass fuel and nitrous oxide therethrough;

wherein each of the one or more nozzles is adapted to be installed between an engine'"'"'s fuel injectors and the engine'"'"'s fuel injector receptacles without substantial modification to the engine; and

wherein each of the one or more nozzles comprises;

a first passage adapted to pass fuel therethrough;

a second passage adapted to pass nitrous oxide therethrough; and

a third passage adapted to pass therethrough a combustion reactant chosen from the group consisting of fuel and nitrous oxide.

2. The nitrous oxide kit of claim 1, wherein the one or more nozzles comprises a number of nozzles equal to the number of fuel injectors of the engine.

3. The nitrous oxide kit of claim 1, further comprising one or more distribution blocks for providing at least one flow of nitrous oxide to the one or more nozzles.

4. The nitrous oxide kit of claim 3, further comprising one or more hoses for connecting the at least one flow of nitrous oxide to the one or more nozzles.

5. The nitrous oxide kit of claim 4, further comprising one or more fittings for connecting the one or more hoses to the one or more nozzles.

6. The nitrous oxide kit of claim 1 wherein the one or more nozzles comprise one nozzle.

7. The nitrous oxide kit of claim 1 wherein the one or more nozzles comprise four nozzles.

8. The nitrous oxide kit of claim 1 wherein the one or more nozzles comprise six nozzles.

9. The nitrous oxide kit of claim 1 wherein the one or more nozzles comprise eight nozzles.

10. The nitrous oxide kit of claim 1 wherein the one or more nozzles comprise ten nozzles.

11. The nitrous oxide kit of claim 1 wherein the one or more nozzles comprise twelve nozzles.
