You need to look at this in terms of the total energy. The problem with simply injecting water is that you'll use more energy to compress (and heat) the air than you'll get back from the expansion of the steam, unless you add additional energy from somewhere.
Energy can be neither created (except in an atomic reaction where matter is converted to energy) nor destroyed, only changed from one form to another. Water injection adds power to engines because it takes some of the heat energy from combustion that would otherwise go out the exhaust and uses it to convert water to steam, increasing cylinder pressure.
Converting water to steam requires that the water absorb energy from somewhere. In your example, the energy needed to convert water to steam would come from the heat generated by compressing air in the cylinder, which in turn comes from the energy needed to rotate the crankshaft and push the piston up the cylinder, which in turn has to come from somewhere.
If there's nothing to add energy to the water, even though the cylinder may be hot enough to vaporize it, there'll be a net loss of energy in the form of heat passing to the cylinder wall and heat created by friction between moving parts. This energy can be added either internally, like a gas or diesel engine, or externally, like a steam engine.

Today's Featured Article - Restoration Story: Fordson Major - by Anthony West. George bought his Fordson Major from a an implement sale about 18 years ago for £200.00 (UK). There is no known history regarding its origins or what service it had done, but the following work was undertaken alone to bring it up to show standard. From the engine number, it was found that this Major was produced late 1946. It was almost complete but had various parts that would definitely need replacing.
