Abstract

KNOCKING combustion (detonation) in Otto-cycle engines using hydrocarbon fuel is attributed by King1 to the effect of finely divided carbon in igniting the unburned combustible mixture ahead of the flame front (the end gas). The carbon particles can, according to this view, be provided (a) by pyrolysis of the hydrocarbon at the high pressure and temperature attained by the end gas, or (b) by impingement of the flame on relatively cool surfaces in the combustion space, as in a method commonly used for procuring carbon black.
