Adding water helps the engine in several ways, including REDUCING the water the engine needs to handle.
Engines normally handle a LOT of water, because each gallon of gasoline turns into 9 gallons of water; which is why the ‘advise’ of having to use stainless steel valves, when you add water injection, is a MYTH.
Because of more efficient combustion, adding water injection normally REDUCES the amount of water the engine has to handle.
For example: Assume a combination of Water Injection and HyZor gains 50% fuel economy with no power or performance loss.
You’ve just replaced 50% of the fuel with water (1/2 gallon). The engine now creates only 4.5 gallons of water from the combustion of the 1/2 gallon of gasoline. 4.5 plus 0.5 is 5 gallons of water instead of 9 gallons of water. You just REDUCED the volume of water the engine has to handle by 4 gallons for every gallon of fuel burned!
Brown’s Gas (BG) contains a large percentage of hydrogen, which turns into water when burned. But the volume of water is practically insignificant. In our HyZor we recommend about 1 amp per liter of engine displacement. With the C version HyZor Technology, running at 5 amps, this will create about 15 liters (of BG per hour) from about 8 mL (0.27 oz) of water. The engine won’t even notice 1/3 of an ounce of water per hour.

The only way to get rust in the cylinders or rings is to eliminate the oil film and GASOLINE is much better at doing that than water. I suspect people who ‘experienced’ engine rusting were flooding their engines with excess gasoline, then even the moisture in air can rust the unprotected metal.
The same goes for the exhaust system. Exhaust systems usually rust from the inside out and they will do so whether you add water or not; though adding water, as explained above, will reduce the volume of water that is going through the exhaust.
It’s a good idea to drill a small hole in a low point in your muffler; this will allow water to drain out and help the muffler last a lot longer. Another idea is to get a lifetime guaranteed muffler. Personally I prefer to get stainless steel mufflers.
