are arrayed around the fuel injector nozzle 27 on the end of the ceramic sleeve 23 that faces the combustion chamber 17 this combustion chamber 17 could within the scope of the present invention be installed in any of a variety of engine types to include gas turbines as well as reciprocating 2 cycle and 4 cycle diesel or gasoline direct injected internal combustion engines fig4 d also shows the same oblique perspective view of the lower portion of the ceramic sleeve 23 as shown in fig3 d with the inclusion of the high voltage discharge 35 occurring between the six electrodes 33 other numbers of electrodes to create the ring of fire are possible also the ring of fire is schematically illustrated in these figures since it is difficult to illustrate completely fig5 a 5b 5 c and 5 d show the lower portion of the ceramic sleeve 23 as shown in fig4 a 4b 4 c and 4 d with the inclusion of fuel being injected by a fuel injector 21 the fuel injection spray pattern 37 of a pintle type of the fuel injector nozzle 27 places a cone of injected fuel centered to the high voltage discharge 35 that occurs between the electrodes 33 inside the combustion chamber 17 this insures complete combustion initiation of all of the fuel as it is injected fig6 a 6b 6 c and 6 d show the lower portion of the ceramic sleeve 23 as shown in fig5 a 5b 5 c and 5 d the difference is that this time the fuel injector 21 has a fuel injector nozzle 27 of the hole type the.
