There's a lot of politics, timing and coincidences as to what is mainstream or not... The MiniDisc is far superior to the CD for instance, but was introduced too late... Anyway, let's not get into a hopeless discussion.
The O.S. 4-stroke aeroplane engine I guess we'd better keep out of the equation.
The PC/RC system as I understand used the carb yes, which is perfectly ok! It sounds like a simple yet effective solution. It logs the servo movements (=amount of throttle opening) and the exhaust temperature. And then adjusts the fuel pressure in order to keep the temperature stable. And according to different profiles. The cold start profile/program probably runs it extra rich for a while.
I THINK (I cannot be 100% sure) that if the big manufacturers did an effort here we could have a great system
That PC/RC company might not have had the necessary marketing resources... think about it - how many heard of it "in time"? And many still deny such a solution can work at all...
The EFRA discusson proposal is written and will be sent in 2009 if it's passed at our national convention in 4 weeks...
I proposed to test it only in UK first!
