Water Injection for Gasoline Engines
Water injection potential within gasoline engines will be evaluated within this paper. Basically, the cooling effect of evaporating the injected water can mitigate knocking. This will result in earlier combustion phasing, in less fuel enrichment for component protection and thereby in higher thermodynamic efficiency.

Epoxy or Polyurethane ? | WATERPROOF! Magazine
A casual debate often will arise over the use of either epoxy or polyurethane for concrete crack and joint repair. Both will fill the crack and prevent water infiltration, so if simply preventing a leak is the only concern, then either product is fine to use. The question of which product is better depends on the type of crack or joint and ...

Explain water injection
It is the latent heat of vaporization that causes the cooling of the intake charge. It takes a bit over 4 joules of energy to raise 1 gram of water 1 degree C in temperature until you get to the vaporization point. You need 2230 joules of energy to turn 1 gram of water (at 99.99 degrees C) to steam or vapor. .

Benefits and drawbacks of engine water injection systems
Just as a fireman sprays water onto a fire to cool it down the water injection in an engine helps to quell ignition. It will literally slow up the burn of fuel and enable a more thorough combustion process. Some advocates of water injection list the cleaning effect this has on the engine and head but this is not a primary consideration.
