On Y-tube looking for safe ways to disarm a LiPo battery … then this on the side-preview area caught my eye…
Complete waste of time, but for a small engine monkey like myself it was interesting to watch.
Dude turns an old car AC (air conditioning) compressor unit into a 3 cylinder, 2 stroke engine.
I knew about inlet and exhaust ports, but never really gave ‘transfer ports’ and ‘reed vales’ much thought before – and his little home made carburettor that visually shows the basic science behind a ‘venturi’ style system.
Ow and the crude but function ignition coil set-up.
After so much attention to detail with everything else, I almost cried when he twisted bare wires onto the 12v battery. (instead diy copper terminals)
I’m not sure how long it’ll last as the three pistons have no sealing compression rings – which I found odd that he didn’t go to the trouble on a small lathe to make.
There’s no battery charging system for the remote pick-up sensors, but my guess is the motor would seize long before that 12v sealed battery would go flat.
And a cylinder head made out of 12mm see through perspex with all that combustion heat? (done on purpose to show the engine firing for the views)
Or, just go to the dump shop and pick up an old whipper snipper for $10 🙂
