Abstract

See full text

An ignition system for hydrocarbon fuels based in part on the principle of 'flame discharge ignition' of coupling ignition energy to the initial flame front plasma either as a 'pulsing flame discharge ignition' or an 'enhanced conventional discharge ignition'. Electrical, geometrical, spark, and hydrocarbon flame front plasma discharge properties are taken into account and adjusted or tailored to create a flame discharge ignition process capable of igniting very lean mixtures. The system is further improved by modifying the fuel's flame front plasma properties by increasing the ratio of the carbon to hydrogen (C/H) content of the fuel and/or by using additives to further increase the flame front plasma density without reducing the plasma recombination coefficient.
