I know of NOx and propane injection and water/methanol.

What would THESE do if injected?

Pure O2

Propane/O2 blend?

Aceteylene?? :eek: I know Acetelyne is a VERY rich fuel, albeit VERY unstable.

Natural gas? the same as propane right?

and I guess really any combustable gas....what'd happen?

O2 -- probably throw a rod from the diesel/O2 explosion. The local gasser that drove through a cloud of pure O2 a few years back only coasted a few hundred feet downhill before stopping and catching fire. I'd be suprised if it even got a full load of O2 into a cylinder -- probably just some significant O2 enrichment. http://www.portlandtribune.com/news/story.php?story_id=16912

acetylene is too unstable to inject into an engine... the fuel autoignites at around 25psi without any oxy... kinda hard to plumb it to the engine... I suppose a acetone impregnated line solution could be rigged up (catalyst to prevent the autoignition) , but I don't forsee any future installations...
oxy could be used, but I think it would cause the cylinders or pistons to melt. if any part of the iron block got hot, the oxy would instantly burn the iron...
Propane/O2 blend... scary.

NOx is nothing more than extra oxygen coupled with nitrogen as a carrier.
why does taking the nitrogen away make it more dangerous?

just a curiosity thing anyway..

Because O2 is a freaking accelerate (oxidizer). mix it with anything on the planet that's flammable and in a closed environment to boot, (cylinder, pipe bomb etc) and it will freaking explode !!!

Ever wonder why they don't like hydrogen peroxide on airplanes ??? 'cause it contains a lot of O2 with water as a carrier.

Why not just blow some black gunpowder down the air intake ??? You'll get the same effect.

Well, you know
 

Since Mythbusters tried that and could not make a lawnmower engine run on it, "Myth busted, it WILL NOT WORK." :rolleyes: Entertaining for sure, but I think they half-ass half of the projects. HEY [1/2 x 1/2] = 1/4 I guess that means they quarter-ass it all the time :D

But seriously, contrary to popular Wiki-pinion Rudy did design his first engine (size of a small building) to run on coal dust. IIRC the museum display said, "..it then destroyed half a city block." There was a Daguerreotype picture with it - pretty gnarly. I guess that means you can put anything in it once.

Pure O2 will work better than NOS in a diesel and there will be no risk of an explosion. It might kill your O2 sensor if you have one.

The reason is NOS has to be heated to a certain temperature before it disassociates and frees up its Oxygen for combustion. Injecting pure O2 will increase the burn rate of your fuel and start combustion a little sooner. Your burn rate will approximate your injectors fuel delivery better. You will also have more complete combustion.

end result is more power.

I should have clarified it.....Gunpowder + Diesel fuel in the intake.

Better yet......Diesel fuel + ammonium nitrate in the intake.

Diesel fuel = flammability

Ammonium Nitrate = O2

Now you have the poor mans dynamite.

Can you say Timothy McVay ???

You need to get your chemical formula right. NOx is the smog forming emissions spewed out the tailpipe. N2O is nitrous oxide.

N2O is 36% oxygen by weight. When the nitrous oxide is heated to approximately 572*F it breaks down to release extra oxygen. The nitrogen that is part of N2O performs an important "buffering or dampening" of the increased cylinder pressures making combustion smoother and more controlled.

I Rigged Up Acetone injection into my 82 300d. It was very simple, pump activated by the kickdown circut, sprayed a mist of acetone right infront of the turbo inlet in the U tube. End result was more power, cleaned out the intake, and cooled the charge air quite a bit. I haven't recorded the temperature yet but it cooled it down so much that I could hold my hand on the compressor side of the turbo after a half hour of driving. But heat soak catches up quick and it gets really hot after a few mins. No ill effects yet, but on an unrelated issue the plastic outlet on the top of the rad cracked when I was changing the hoses so now I am sitting here waiting for parts. It was the same day I rigged up the acetone circut and I was just starting to have fun :( Pics available of my setup and wiring if anybody wants.
