Pulsed plasma jet igniters have been shown to be effective in enhancing the flame speed of combustible mixtures of gases. The mechanism by which this enhancement is achieved is somewhat unclear, although the consensus of recent investigations is that the possible mechanism involves the inherent gene

β¦ Synopsis
The electron temperature, ionization density and flame speed were measured for a propane--air flame which was immersed in a microwave field at frequency 2.5 GHz and maximum field strength of 1.9 x 104 V/m. Although the electron temperature in the flame front was increased by 55% and that in the downstream burnt gases by over 100% there was no increase in either the ionization density or flame speed to within the accuracy of the measurements (a few percent, depending on the technique in question). The electron temperature was measured for a near stoichiometric flame at field strengths approximately one-third of the maximum value, while the flame speeds were measured at maximum field strengths and for flames as lean as ~ = 0.69.
