Hydro-Steam Propulsion


https://1.bp.blogspot.com/-qIaYL4Y8A...dgasdgasdg.JPG

The illustrator, who is very versed in steam locomotives (http://justacarguy.blogspot.com/2016/03/william-harnden-foster-most.html) put this out as disinformation. It's bound to fail! The convergent duct is a brick wall, it will choke the venturi; and the steam injector is a T instead of an L so that it will be some additional blockage.

They are trying to throw us off the scent. Study it out.

In the mountains, too. I think it's for water.

jakobnev -- Another drawing. I wonder what the air input is for. Do you know if that was constructed or tested?

...or a ram jet that uses steam instead of combustion to expand the exhaust.

Steamrollin

With all the idiots 'rollin coal' around my neck of the woods in their absurd trucks, I'd like to reciprocate with an enhancement to my sensible, stock-height grandpa truck ('87 F250 IDI 6.9 Liter).

Anybody explored water injection into the exhaust for brief but billowing clouds of steam? I'm thinking that sure, it'd increase back pressure and actually hurt performance during use, but not enough to damage anything if done judiciously.

Initial idea is to weld in a bung to the steel downpipe after the exhaust manifold, keeping the manifold nice n hot and avoiding any thermal shock to the cast iron, using a water/methanol injection nozzle and pump on a momentary switch.

Having a valve and controller to use water injection for economy or occasional steamrollin would be even more fun.

Couldn't it be in the tailpipe tip, to reduce corrosion upstream?

And what's the methanol for, anti-freeze?

Here I was thinking into adding a bubble blower to my exhaust.

Salem, OR used to have city buses called Cherriots that had (maybe still do) diesel exhaust that smelled like cherries.

No methanol, just running water through the weld-on injectors sold for methanol/water injection on intake manifolds.

I proposed placing the injectors 'high' in the exhaust system to get maximum vaporization via dwell time, turbulence, and the built up heat in steel pipes. I'm not worried about excess corrosion. After all, there's already a lot of water vapor in exhaust, and this is only something that will work after warmup. As long as one doesn't get the exhaust system all wet right before shutdown, why would it matter? I'd expect that soot removal from the steaming would be pretty effective.

That being said, this would be most effective in winter, and exhaust tip injection might be the only way to make the steam visible for more than a second in summer.

I think you're on to something here. I've read in other gas engines where exhaust water injection is used to create a reflective wave which dynamically "tunes" the exhaust system (via exhaust gas scavenging) to improve torque and horsepower at rpm bands other than what the original system was designed for. May be kind of a nice thing when you're pulling a stock trailer vs. putzing about town.

I don't see that a large amount of water would be needed, just enough to reflect the exhaust pulse. And I doubt enough energy would be absorbed to change the temperature of the iron manifold in any significant way.

Further, on a turbo set up it may be a nice way to keep the turbine de-coked.
