The products of robust combustion continue downriver and penetrate and mix radially outward until attain the surrounding cylinder gases. At a localization of function where the rich products and cylinder gases mix to vex a stoichiometric mixture, a public exposure flame is produced. The dispersion flame surrounds the natural spring in a thin turbulent sheet, which extends upstream towards the beak. The axial distance from the bird of night exit to the public exposure flame is the lift-off length.

HEUI uses a hydraulic pressure intensive arranging with a 7 1 pressure ratio to generate the dead reckoning pressures. The hydraulic pressure is generated by pumping engine lubricator to a manageable high pressure. sympathetic to CR snapshot organisations, there is control of the shooter pressure.
