$300 Hydrogen on Demand unit here. Was just up at the hardware store. Couple of guys that work at ACE have installed this unit manufacuted by one of their regular customers. Both claim it has improved gas mileage and hp. Are they just trying to justify their $300 investment?

You already have one of these in every car, its call a battery. Just run some lines from your battery caps into the intake!

100+ MPG "carburetors" (it's actually the whole motor design, not just the carb.) do exist.

Current internal combustion motors are all built to burn a fuel/air mixture. They operate like "steam engines" and actually capture relative small amounts of the heat energy available in the (gasoline) fuel. Most of the heat energy is wasted as hot exhaust gases out the tailpipe.

Extreme efficiency internal combustion motors detonate a fuel/air mixture and are designed in such a way that the piston is moved by the shock wave of the detonated fuel/air mixture, not by heated expanding gases.

It's a fairly simple design: boil the gasoline (using the heat from the exhaust is the most efficient way), mix it with air, compress it in the cylinder, ignite it with the spark plug. At certain motor speeds -- when the moving piston can capture the kinetic energy of the shock wave from the detonating fuel/air mixture -- extreme motor efficiency will be observed.

You will have a better chance of making a gererator work.

Do you really think that all the automakers in this world with all their billions of dollars and all their top engineers can't make it work, but your local neighborhood wrench can? do you? Seriously.

Grady Clay can demonstrate how you can get more power for your 911 using water and a spare injector. And the water never has to enter the combustion chamber...

I have seen some of the 'large aircraft engines' that use water injection to delay detonation at high power settings. Usually a small bubble of air going down the fuel line from a sloshing (or empty) tank lets nothing but the water into the cylinders.

The reason I have seen these cylinders is because there are always a pile of them full of holes and missing large chunks outside every large aircraft engine rebuilders' shop in a box that is going to the smelter to be made into Hyundais.

Water can increase the massflow and power output of many types of engines. But it will not increase the efficiency, in fact, because of the loss in the heat of vaporization, it will reduce efficiency.

Water can also be used to reduce the flame front temp in some type of engines, reducing the production of NOx.

In the olden days, guys used to inject a small amount of water into the air intake. In the combustion chamber, the water turns to steam and expands. Hmmmmm........

In the olden days, guys would light a fire under a boiler half-full of water, and I seem to remember they had a somewhat similar use for expanding steam.

Right you are and to this day, steam can produce pretty as much power as is needed. The speed or power of a steam engine is only limited by the metal used.

Not true. Steam dissociates. It is the reason that steam thermal plants are limited to 42% thermal efficiency.

just don't forget the magic crystals....<BR>

Been debunked on mythbusters i believe.

BTW, water injection does work, period. Just ask any WWII fighter pilot.

the JT3D was also water injected. ....also a lot of fast and furious-types have water injection in their intercoolers on subarus, etc.

I am typed and have too many hours in an F27. Rolls-Royce Dart engines. Water-Methanol injection for takoff power 'boost'..... Lots of funny stories. Does it work?

It made the young guys in the right seat feel good. The trees at the end of the runway at Grand Canyon looked exactly the same as they went underneath the retracting gear with the water on and working and as with the water on and not working.

I would say on pucker factor alone it wasn't worth a %%%%

I explain thermodynamically why it won't work, ever, period.

LOL if you guys really need to believe this crap, go ahead.
H2O injection was and is used occasionally to reduce pre-combustion and detonation in an engine, but it is a band-aid to cover up another problem and it DOES NOT CREATE POWER, it only reduces how much would otherwise be lost because something isn't right. If the mixture, timing, and combustion ratio were correct to start with you wouldn't need water injection and you would be way better off as far as power and efficiency.

In WWII they figured out if they cranked the boost waaaay up they would make more power but it would eat up the engines when they started pinging. So they injected water to reduce the combustion temperature and save the parts. It also took away power. That's right, the water TOOK AWAY POWER. They'd have been better off reducing the boost, richening up the mixture, and leaving the water on the ground to save weight.


And Supe, since you are obviously an expert on steam propulsion how much energy does it take to create a pound of steam? How much water and steam pressure would be requred to push a piston down with enough speed to make a given amount of horsepower when copmpared to internal combustion? What would the RPM limitations be?

Reality check on aisle 3. If there was anything to this crap we'd already be all over it. Much better minds have tried and dismissed it as either bunk or completely impractical.
Just because you want it to be real doesn't make it any less fantasy.

Water injection does allow for the creation of more power.

Check out the HP ratings of various US fighters from WWII sometime, both with and without it. Typically water injection adds about 200 horsepower to a high output WWII fighter engine.

Next someone will be saying that you get more horse power on a cold day! Oh, wait, you do...

"In the H model (Mustang), the structure was increased in strength by 10%, to allow higher "g" loads in combat maneuvers. No structural part was left in common with earlier models. Streamlining was improved to increase speed, and stability was increased. A new version of the Packard/Merlin, incorporating water injection, delivered over 2000 hp."

Water injection works. The P-51, BF-109, FW-190, TA-152, P-47 and a variety of other WWII aircraft all used water or water-methanol injection in WWII. It works.

Carry on.
