variable advance for crankshaft sensor?
(OP)
hi, i've got a test engine in my school that needs a variable advance for ignition. triggering is by a crankshaft sensor. does anyone know how to build a circuit for mating with the crankshaft sensor to provide a variable advance for the ignition. I'm not too sure but a delay might work also as 350 degrees delay is the same as 10 degrees advance?
Thanks
Thanks





RE: variable advance for crankshaft sensor?
Something that I would look into is some of these single board micro controllers that program in Basic. They have IO ports & some have A/D ports. I think you could hook up a pot to the A/D port & make its value a variable to multiply you advance or retard by. This way you could adjust with a knob.
You probably need to check your signal from the crank sensor with a scope & get a controller capable of mimicking it. You would want one that could time input pulses and then make the next output pulse the same time + or - your time change.
