No sorry, I'm not referring to the 6 stroke as described earlier in the thread. Water would be injected into the combustion chamber right before the compression stroke.
Another idea I have been considering is preheating the injected water. Obviously it would lower the ability to prevent detonation, but keeping the water close to the temperature of phase change would allot more of the energy to increasing cylinder pressure through water vaporization rather than just getting the water to that point. Does this make sense to anyone who is a little more calculator friendly?
