I have an engineering handbook written in 1892 that details almost every aspect of a steam locomotive. I found it interesting that they had experimented with injecting steam into the firebox to generate hydrogen and oxygen. They decided that there was no advantage because the amount of energy to make the H2 was the same as the energy it produced when it was burned to form water again.

Look at these guys making a steam car or steam engine for a car, they claimed the California CHP has a few of them that can do 140mph! https://www.mikebrownsolutions.com/steamart.htm These article has an interesting take on the whole steam powered car https://www.stanleysteamers.com/modern_steam.htm It seems that Steam power has to make a come back if we want FE not just in our cars. |
You have some very good questions here, this is my understanding so far.

I am no steam expert on steam or this system , I am just learning right now, I am surprised Honda is making 30 to 43Hp using this system and with only 13% efficiency, this means 26% would recover 60 to 86hp, 50% would mean 120hp to 170hp extra, they need to talk to steam engineers! ASAP I have a wall paper stripper and I am tempted to plumb it into my intake manifold just to see what happens at idle, hopefully no boom! |
Actually if you use steam that's barely dry at 100C ish then superheat it in the combustion chamber it's SHC goes up and you get a mild efficiency gain from that, plus you reduce pumping loss at low throttle opening.
BTW I think they did a better steam injection thing in 1920s or 30s era locomotives, seem to remember hearing about using steam for forced draught, basically using the kinetic energy of the steam to pull air through the firebox or something like that. |
