oxy fuled engine

admin

I have an old cement mixer engine and i devised a plan to gear up its horse power with o2. It would be injected strait into the carborator and used like nitros. I want to hear your comments on thisMY Shop Gear::1: a rock and string2: glass bottle and gas3: old remote and batteries4: metal taped together5: ripped shoe6: smash anphibious water craft

Reply:Oh Scrapster.  Is this another story to provoke controversy?O2 isn't flammable, but it sure can help to burn other stuff with it's oxidizing effect.  Why not just use nitrous like everyone else?  Or are you going to make your own from separating the hydrogen from the oxygen molecules of water?Hobart 140 Handler w/ gasHyperTherm Powermax 380 Plasmaoxy/acetylene

Reply:Pure O2 is flammable but burns too lean and hot and will melt the engine.  Nitrous on an engine uses nitrous and fuel.

Reply:I think someone's on "Oxy"..... ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:Scrapster, Even though you pimped me, I'm gonna help you out.When I was involved with automobile (real) final quality testing; one of the tests once performed was oxygen injection. There was never found a need to perform this test again.It blew the top out of the intake. Not joking, not kidding. It blew the intake casting half off, and put a hole in the hood. Of course we were experienced and careful testers, so no one in the "laboratory" was anywhere near danger. I'm serious about this; don't mess with it.Last edited by denrep; 12-12-2007 at 11:32 PM.
Reply:I believe it could be done , but , not practical, unless you have unlimited time & money . You'd need ultra accurate measurement of the oxygen & the added fuel source, with the usual solenoids,etc. .................without added ,measured fuel, the oxygen is a blow torch into the intake.[SIZE="5"Yardbird"
Reply:I think the dangers of a backfire would be rather spectacular as well.Nitrous can be found rather cheaply if one were so inclined to try it.

Reply:It's been done sucessfully in submarine engines for countries that don't have nuclear subs. I'm sure millions of $$$ stuff was blown up before they got it right. It's not something you're going to get working with backyard technology.
Reply:The other danger I am seeing here is pure oxygen in the presence of an already extremely flammable substance... ( NO oil anyone? )

Reply:OK then, ScrapsterMaybe you could share with us your experience with building and tuning HP motors, ie: turbo, supercharging, fuel injection, normally aspirated carburation, jetting, ignition timing, valve timing, manifold, cylinder head and exhaust air flow, boost pressures and enhanced mixture charging?Then you can follow that with what you know about chemical reaction and molecular structure.Go on to describe your experience with machine shop equipment, ie: lathes & mills, and what other equipment and material you have available in your garage to aid you in engineering and fabricating the different components of this project - besides "an old cement mixer engine".Then, we may take this thread more seriously.  Although my feeling is that we will inevitably reach the same conclusion.I'm not trying to stop you from dreaming, but you may want to start with something simple and work your way up before you hurt yourself or someone else.Hobart 140 Handler w/ gasHyperTherm Powermax 380 Plasmaoxy/acetylene

Reply:I thought about this years ago and the theory is sound ..... the problem is in trying to make it work safely.Nitrous oxide allows an oxygen saturation of 33%. Air permits a maximum saturation of only 21%. In theory running pure O2 would allow you to achieve near 100% saturation. The problem is you need to get enough fuel into the chamber to match while preventing pre-ignition. Direct injection technologies might allow this as long as you could keep the piston temps down ... maybe with ceramic topped pistons or some other coating that doesn't break down.If you've ever been within 20 feet of a nitrous backfire in the intake you'd know just how dangerous this can really be. Air/Gas isn't that flammable comparatively speaking and has a relatively high autoignition point. NOS is an increase of about 12% and blows stuff up all the time .... increase this another 60% and shrapnel is going to fly

Reply:I've seen concrete burn with an ignition source and LOX (liquid oxygen). Pretty much anything will serve as fuel in an oxygen rich environment, if that environment consists of only fuel and oxygen and very little inert matter, you're going to have a very violent explosion. The questions here in my mind are... do you truly understand everything you're about to do? (by truly understand, I mean have you actually done the math?)What is your safety factor?Until you know exactly what the force of your explosion is going to be, based on the quanities of fuel and oxidizer present, pressures, etc., and if your heads, block, etc., are designed to withstand the pressure of your explosion... I wouldn't really just "try" it, unless you do it remotely.Good luck with that whole thing...My toys includeMiller Bluestar 2E AC/DCMiller Thunderbolt 225O/A outfitMany saws, grinders, drills, etc.

Reply:Injecting oxygen into a gocart engine can be done, but it will require a few things that will defeat the purpose of the project.  You don't seem to have an expensive laboratory at your disposal, and indicate you want to do this as a backyard project.  This will require one of three things:1. A bunch of engines to experiment with, and something between you and the engine being experimented on to contain the inevitable engine explosions.  There are expensive labs with million dollars of equipment and many researchers that are still blowing engines up with oxygen, so this isn't a "might" happen thing.  You are 100% guaranteed to blow up engines experimenting with this.  That's engines, plural.  Nobody in the world, no matter how much experience they have, is able to build a backyard oxygen injection engine without some catastrophic failures in getting the injection system right.  With an insane amount of luck, you might get an engine to be relatively stable (engine lifespan over 1 minute) within 20-30 tries.  Realistically, probably 100 or more.  This would get expensive, unless you have a large supply of free engines.  It'd be cheaper to get the engine off a Suzuki Hayabusa, turbocharge it, and have a 200+HP gocart.2. You will need a large, empty area to test it on the go cart, and some heavy sheilding on the cart between you and the engine.  Like 1" thick plate at the minimum.  Unfortunately, this will add a ton of weight to the gocart, making it way slower than if you just used a regular engine and no sheilding.  Plus, you'd still need a bunch of engines.3.  Build the engine on the cart, have no sheilding, and maim or kill the driver with every mistake.  You would still need a bunch of engines, and either immortality or a lot of expendable minions.  I'd go with option 3, if I could afford it.  I've always wanted minions.  They're just so useful.PatrickLincoln 175HD
Reply:Why not ad a small turbo? And then ad some diesel injectors right before the turbo to spray mist of water inside the exhaust header that expands and make sh*tloads of exhaust\water expanding mist to the turbo rotor?  I would like to see that working for 2 seconds on that engine My welds looks like Shi*!
