Don,t know about how many smaller engines are in the works....but a smaller ignition is being developed...thats is all I can say. It was a promise................[img][/img]
how much smaller can they get and still be reliable i wonder. remember that the smaller they get the closer all the components inside the case are going to get. the downside here is on the high voltage side the spark will look for the easiest path to jump across? which may no longer be the spak plug gap. we also seem to want them to be HV capable, again the higher the input voltage gets the quicker it will look for a way out ? no doubt improvements can only be made through testing and the need for something new, so if something is being done great. I still dont see a problem with the igntions the way they are though. but i also dont fly warbirds with no room
Ohlsson & Rice and Forrester used to make .23 and .29 CI spark ignition engines back in the '40's and they seem to've run fine.............
