Basically the piping is designed to drain back the water to the reservoir when not in use. The reservoir is weatherproofed. Given the fact that this system is auxiliary; it doesn't have to be operational for the engine to run, so even if water does freeze over in the tank the engine will still run | |

Now water injection isn't a new concept; It is not, that is true: It has been in use in aircrafts even predating WWII to provide a performance boost.

| Sep 3, 2016 at 0:48 | comment | added | Lathejockey81 | I believe the difference here is that in the 6 stroke engine water is being used to extract power, so there must be enough to actually expand adequately to pressurize the combustion (evaporation?) chamber, where water injection in a four stroke is meant to use evaporative cooling to prevent knocking, which requires significantly less water. | |
