Summary

Required ignition energy changes within the flammable concentration range. Based on Beyler (2002), p. 2-181, and Iqbal and Salley (2004), p. 16-4.

Original illustration for Minimum ignition energy, level 3 Advanced.

Source basis: Beyler (2002), p. 2-181; Iqbal and Salley (2004), p. 16-4, Figure16-3; qualitative synthesis, not digitised data; redraw, do not copy.
Alt text: A qualitative curve shows higher required spark energy near the lean and rich boundaries and a lower intermediate region.
Accuracy notes: Do not assign one universal concentration or energy value; the minimum need not coincide exactly with stoichiometry.
