Soot inception temperature

TABLE 8.6 Soot Inception Temperature (K) by Various Investigators... 

The kinetics from here remain even more uncertain, but the polyacetylenes clearly must acquire charge very early in the sequence since charge affects the soot formation from its inception. Other charging mechanisms are present almost certainly once soot nuclei are formed. The experimental ion traces must be evaluated cautiously because of the nonideal wave effects responsible for a pressure and temperature rise during the most rapid soot formation, i.e., the latter part of the fuel-lean combustion. The substantial increase in ionization approximately 1.5 msec after the shock passage cannot be explained by nonideal effects and kinetic arguments. Instead, once the soot is formed, thermionic emission...
