The basic idea of water injection or these new 6 cycle engine designs is that the water is utilized to scavange waste heat that would otherwise be dissapated in some other form.... such as the cooling system, radiant or form oil cooling. The water captures the heat, expands as it vaporizes, and that expansion energy is captured by the piston. The key is that there needs to be heat energy from some other source to make the steam. What I read about the new 6 strok concept is that it is so efficient that it eliminates the need for a conventional cooling system. THat would be a gain of somewhere in the neighbourhood of 30-35 percent in thermal efficiency. That's not a bad number! It might hold some promise if they can figure out a way to make it practical.... so that the water doesn't freeze in the tank.
