I want to build a nitro rc engine dyno to tune engines dynamically, at present you can only a chassis dyno that after a run, will tell you engine rpm, peak torque and power curves etc for the whole run. I was thinking of using an inductive pulse generator on the flywheel but this will only tell me a calculated rpm from peak to peak voltage and frequency.
I was wondering if anyone knew of a way i can maybe use a generator with a known physical resistance(drag) that will give me a required power output to generate an output (1kw/1.34hp will generate so many watts etc..)
or
to activate a low power electric motor opposing crankshaft rotation, to give a known load, then measuring the back emf that is created by the force of crankshaft rotation.
thanks
