I don't know what all Pantone invented. I don't think water
injection was in his patent though. It certainly should have been
rejected if it were.
It cools the exhaust and gives extra steam pressure in the cylinder.
Others do it differently: patents on that white goop; water/gasoline
emulsion.
IIRC, too much water significantly reduces engine life via hydrogen
embrittlement, so the inventors' goal of water/gasoline engines would
actually be a goal of non-metal auto engines: ceramic engines or
ceramic
coated pistons and cylinders.
Ceramic engine parts sound good for other reasons too. They can be
pretty slick, catalytic, and run hot too. However, I've seen first
hand in recent years a tractor with water injection that has been
running since the 1940's. I don't know for sure how many hours it
had on it, or the water injector, but it looked well used.
