Abstract

An injection nozzle utilizing nitrous oxide to aid in the introduction and atomization of fuel into a combustion chamber. The present invention comprises a Y shaped nozzle having a pair of input ports and a single output port. One input port is utilized to introduce nitrous oxide into a hollow sleeve of the nozzle and ultimately exiting at the output port. The second input port introduces fuel to the nozzle. A fuel line coupled to the second input port extends the length of the hollow nozzle, terminating at the output port extends the length of the hollow nozzle, terminating at the output port. The nitrous oxide is introduced at high pressure, approximately 500-1000 PSI. The fuel is introduced at approximately 3-12 PSI. As the nitrous oxide exits past the end of the fuel line, it creates a vacuum which aids in drawing the fuel from the line. In addition, the high pressure and vaporization of the nitrous oxide atomizes the fuel so that it is fully dispersed and once within the combustion chamber may be more efficiently burned.

Dependent claims

A method of injecting a mixture of fuel and nitrous oxide into a combustion chamber of an internal combustion engine, comprising the steps of:

conveying said nitrous oxide from a first reservoir to a first input port of an injection device at a first pressure;
conveying said fuel from a second reservoir to a second input port of said injection device at a second pressure, said second pressure being greater than atmospheric pressure and substantially less than said first pressure;
releasing said nitrous oxide through an exit port in said injection device such that a low pressure area is created adjacent to said exit port into which said fuel flows;
allowing said fuel and said nitrous oxide to mix and enter said combustion chamber.
