Re: Electronic Governor
From a theory stand point electronic gov is not all that complex but putting it into real world terms (commercially available for a variety of engines) a little more complex. The gov will need some way to know what speed is wanted. Some feedback telling the control what the actual speed is and then a way to change the speed as needed.
The problem I see is, how to tell the gov what actual speed is. So many engines configurations that making a universal control is a real hurddle. Do you try and read directly off the crank? Lot of hardware needed to fit a variety of engines. Use ign pulses IF this is a gas engine and if a gas engine, how may pulses make one revolution?
How do you change the throttle? Vac diaphram doesn't work for diesel. Could use servo motor and mech linkage but may need a lot of different hardware to implement for a great variety engines.
If one were to design and build their own, for a specific engine, all the problems of implementing a universal design would go away.
This is how I see it but YMMV
