I could see a hot vapor system working. But, I think the biggest issue is the emissions. The other big issue is this system running in cold weather or during a cold start. Will it work when the engine is cold or will it switch over to hot vapor once the engine has warmed up?
I guess the other issue I saw is the test engines used forged pistons, rods, and heavy duty rings. That could be an issue if this system was ever sold as a retrofit. The cost of the system and then upgrading an engine could get very, very expensive.
Thanks for sharing.
