Patent ID: 6935322

Claim:
An air supply conduit for delivering a stream of air to an internal combustion engine and a nitrous oxide and fuel injection assembly mounted to said air supply conduit, said fuel injection assembly including: a support member mounted inside the air supply conduit, a connector extending from said support member to the outside of the air supply conduit, a fastener mounted to said connector outside the air supply conduit and holding said support member to said air supply conduit, at least one injector nozzle extending from outside the air supply conduit through said connector through said support member, and into the air supply conduit, said injector nozzle including a fuel orifice and a nitrous oxide orifice for communication with the stream of air moving through the air supply conduit, a fuel supply conduit and a nitrous oxide supply conduit in said injector nozzle in communication with said fuel orifice and said nitrous oxide orifice of its injector nozzle for injecting fuel and nitrous oxide into the stream of air moving through the air supply conduit, said nitrous oxide conduit and said nitrous oxide orifice configured to feed liquid nitrous oxide to the air stream and to induce the nitrous oxide to evaporate in said air stream; and a control valve for controlling the flow of fuel and nitrous oxide through said conduits and said injector nozzle.
