Abstract
The present invention provides a cyclonic precombustion mixing chamber or prechamber having an axially extending annular cyclonic chamber to vaporize liquid fuel therein and a centerbody centrally disposed within. A fuel injection means introduces liquid fuel radially outward into the cyclonic chamber. The centerbody extends axially through an annular exit of the prechamber to define a throat and throat exit therebetween which is optimally designed for preventing backflash and autoignition. In one embodiment the diameter of the throat is sized to substantially match the diameter of the potential core. The diameter of the potential core and the centerbody at the throat exit, D.sub.c, may given by the solution to the following equation;
