I had a mechanic friend in Bundaberg years ago that modified his HG Holden to run with water or water/metho.T1 Terry wrote: ↑Sat Dec 12, 2020 1:17 pm
That fuel was 50/50 water/methanol, injected into the intake after the turbo and it pulled the air temp below zero enabling a lot more air to enter the cyls per cycle. The methanol boiled off under compression and the water absorbed the huge temperature spike that normally caused detonation and shattered piston ring lands and blew head gaskets as well as melt piston crowns. When the pressure and heat reached extremes, it was suggested the water actually separated into hydrogen and oxygen, then ignited itself recombining into water droplets and exiting through the exhaust increasing the density and therefore increasing the efficiency of the turbo. That bit was widely disputed until a study and later book called, solar, water, hydrogen where they show the splitting of the water into hydrogen and oxygen is energy related and was not restricted to electrical energy, but any energy in large enough quantities caused the separation of the bonds.

He had a small jet drilled into the carby just under the butterfly and the vacuum of the intake would pull the mixture in.
Usually he ran it with straight water, mainly for economy and to keep the inside of the engine steam cleaned, but he often towed a van as well and would do the 50/50 mix for some more power.
I always wanted to give it a try, but never have.
I have been thinking of late to try it on my diesel in the bus.
No butterfly of course, but with an old washer pump to inject it through a jet of some sort...
Hmmm.
