Recently particular interest appears in non-equilibrium plasmafor ignition and combustion control.

The same principles still demonstrate high efficiency in different applications. There is no other adjustment applied other than the steps outlined above.The history of application of thermally-equilibrium plasma for combustion control started more than hundred years ago with IC engines and spark ignition systems. Also, see the newly added two bonus tips at the endīelow are the above images in a larger format for easier comparison.In my trials, setting the blend mode to Color gave better results probably due to the combined effect of hue, saturation, and luminance You can also change the blend mode to Hue and compare it to the Color setting.
