Flame-propagation rates in ammonia-air combustion at high pressure

The reluctance of ammonia to be ignited easily and the necessity to advance the spark for optimum performance in combustion engines led to this investigation. Ionization gap techniques showed that long induction times and slow flame speed were both contributors to the observed phenomena. The most important factor in determining combustion characteristics of ammonia was found to be the extent of predissociation prior to attempted ignition. There was evidence from combustion gas analysis that NO+was the probable most abundant ion contributing to successful application of the ionization gap techniques, and that the NO+was probably produced in the pyrolysis of ammonia rather than by equilibrium reactions.
