ABSTRACT:
The high cost of fuel injectors for use in small scale environments is avoided in a fuel injection nozzle structure including a simple tube 10 used as a fuel injecting tube and having a fuel injecting end 12 received in a reduced diameter outlet 18 from an axial air flow chamber 20 concentric therewith. A swirling air flow chamber 34 surrounds the axial air flow chamber 20 and includes an annular, axially facing outlet 36 concentric with a diverging exit 24 from the reduced diameter outlet 18.
