The reason why Russ is using so much spark power (500 joules ) is because he is following the system that Bob Rohner built which does NOT use pre-ionization. The new control circuit that Russ has invented will pre-ionize the spark channel with a low amperage high voltage spark of about 90, 000 volts from two auto ignition coils wired in series. This will switch in the high powered spark discharge from this capacitor bank at about 350 volts. This is called “Triggering in a trigatron spark gap”. http://en.wikipedia.org/wiki/Trigatron for the theory, see: http://www.google.com/url?sa=t&rct=j&q=&esrc=s&frm=1&source=web&cd=7&cad=rja&sqi=2&ved=0CEwQFjAG&url=http%3A%2F%2Fdigitalcommons.unl.edu%2Fcgi%2Fviewcontent.cgi%3Farticle%3D1022%26context%3Delecengwilliams&ei=R_PIUN_YCOTD0AGMroDYBg&usg=AFQjCNEs1s7LOYnRaKBY4XIihziFcWZAEg&sig2=KhJ0T3Lkdd_I_ol5YZEcAw This is an innovation that Russ will test to reduce the power needed to ionize the penning gas mix. Papp used RF or spark voltage to regulate the speed of the engine. Russ will use spark timing as is currently done in gas engines. Cheers: Axil * * * * * *
