There are also other methods using water - The old "Carbide Lamps" had water dripping onto a carbide block to produce acetylene that was then burnt to produce the bright lights of the early cars - also the lamps in movie projectors before electricity. Can an internal combustion engine run on acetylene?
Yes it could, it has the widest flammability range of any fuel gas, and pretty high energy.
One problem- it's unstable above 15psi. Bottled acetylene is dissolved in acetone which is held in a porous mass within the bottle. (I know this crap because we used to make them at Rheem).
That's why acetylene bottles must be stored and used vertically, and there are draw-off rate limits based on the bottle size..
Another reason- the water to calcuim carbide process used to produce `wet' acetylene stinks bad. Used to be used in farmers bird scare guns last century. We had a couple.
