He talks about this being best used as a diesel.
Diesel combustion takes place between 1300F and 1650F. It's probably safe to say that the combustion chamber gases are going to be in that temperature range. So assuming a 340F flash point for water, it would seem that "getting up to steam" would be no problem at all.
A nice side benefit of this process could be a reduction in NOx. Diesels are particualrly dirty when it coms to sog emissions because they create more NOx at their typically the high combustion temps. If this could be controlled by a timed water injection, it could be a big emissions breakthrough.
Just a thought.
