Abstract
A method and apparatus are disclosed for inducing a supercavitating flow inside a fuel injection nozzle orifice to reduce the penetration length of the fuel spray, maintain high levels of fuel atomization, and improve uniformity of the fuel spray exiting the nozzle such that high-pressure injectors can be used on small engines. This reduction in penetration length is accomplished without any reduction in upstream fuel pressure.
