It's better than creating a new thread. The discussion isn't over. And Mazdamatt, you should have just sent me a PM instead of posting.

And @Christ, you remind me of the whole oxygen sensor in the exhaust problem. How would the ECU handle the steam in the exhaust. So long as it was steam, I'd think the sensor wouldn't register the oxygen content. But I still don't understand if steam affects "Lambda."

A side note, Hydrogen injection increases FE by as much as 25%, something to do with changing the burn characteristics, but storage tanks are still a problem. Getting hydrogen is easy with electrolysis, efficiently generating hydrogen takes a bit more.

Low temp materials as in coating the combustion chamber? It might work and only might if the only time the engine ran without injecting water was during colder weather where water froze and the cooling was unnecessary and when idling or start ups keep the operating temperature low enough to keep the material in ideal conditions.

Removing water from oil would invariable mean providing an escape route for the water which should get hot enough to convert to steam. Dry sump that seperates water? Do you have an example?
