Document Type and Number:
Japanese Patent JPH02502661
Kind Code:
A
Abstract:
An ignition system for hydrocarbon fuels based on the principle of "flame discharge ignition" to couple ignition energy to the initial flame front plasma (32) to convert the flame front (31) into an ignition discharge in which electrical energy is efficiently coupled to the propagating flame front, either as a "pulsing flamme discharge ignition" system 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 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 so that the C/H ratio falls in the range of 0.5 to 2.0, and/or by using additives to further increase the flame front plasma density (35) without reducing the plasma recombination coefficient.
