I know what it monitors and that it adjusts the carb, but how? Are there little screws and the computer activates servos to turn them? Some sort of fuel pump system and it adjusts the pressure? What's going on in there?
Something like this...
"A turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster." Jeremy Clarkson
It's all based off RPM. Fuel is pulled, the RPMs checked. If the RPMs are higher, it figures it was rich and pulls more fuel. If the RPMs drop, it adds fuel. This happens several times/second. It's a regular carb, except that the H needle is replaced with a small servo. Everything is in the coil and the carb.
How about temp and air pressure sensors?
Great videos. Interesting how it uses a magnet coil similar to a voicecoil on a speaker to move the "needle" that adjusts the fuel flow. Great idea.
So I guess the computer etc gets all it's power from a small generator coil on the saw or something? Is there a small battery that will need replacement at some point or is it all just capacitors evening out the voltage flow etc?
