I think this idea is even more practical than the original 6 cycle setup. The bottom steam engine cylinder could be engineered as a regular steam engine with the exception that it would generate its own steam when water was injected. The two cylinders would be constructed so that the heat from IC engine could be used by steam cylinder.
A temperature monitor would determine when the water would be utilized, the rest of the time it would just idle.
My first post, nice forum!
