Would water injection accomplish the same thing?

My engine is largely aluminum (except i assume the cast iron sleeves and rings and valves) so I think injecting water would help increase MPG by adding more water vapor to the exhaust, which would cause the engine to run "leaner" I think without having to worry much about rust buildup.

Does anyone have a clue on how to make a 4 stroke work as an 8 stroke? There's old engine designs that would skip every other intake event and simply pump in air. If i could flip a switch to get the injectors to skip every other signal, I'd have an 8 stroke, and running plain air into the cylinders wouldn't hurt anything. I'd lose power and would have to open the throttle more to compensate, but if I'm not mistaken that would be more efficient, correct?
