A fuel injector adapter for providing nitrous oxide to an internal combustion engine is disclosed. The nozzle has a fuel injector passage, having a central axis and terminating at an injector outlet, for passing fuel from a fuel injector to an engine. The nozzle also has one or more first auxiliary passages, which may be arranged in an annular pattern around the fuel injector passage, and which terminate at first outlets. The nozzle furthermore may have one or more second auxiliary passages, which also may be arranged in an annular pattern around the fuel injector passage, and which terminate at second outlets. The first auxiliary passages and second auxiliary passages are adapted to supply nitrous oxide or other additional combustion reactants to the engine. The nozzle may be attached to an engine intake and may be adapted to fit between a fuel injector and an engine without substantial modification to the engine.

Fuel injector nozzle adapter

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.
