need a free sample first.......1000 pounds should do.

You evacuate Toronto, Vancouver, and NYC. I'll call Homeland Security and the RCMP. We don't another 9/11 on our hands.

not to mention the 'cutting torch'effect.with pure oxygen going into a hot environment,the metal that the engine is made of would become fuel,as when you use a cutting torch....it doesn't just melt the metal away-a jet of pure oxygen is shot against heated metal,causing the metal to burn.....in chemical terms,burning is simply combining a fuel(such as iron[fe])with oxygen[o] to create another compound(ferrous oxide,also known as rust when the reaction happens slowly).this reaction also works well with aluminum(producing aluminum oxide)and almost any other metal.atmospheric oxygen content is about 21%,most of the rest is nitrogen....this buffers the reaction,even in a compressed state...although it is more volatile this way.consider the way blowers used to fly into the air before straps became mandatory.

i dont beleive that is exactly how it is. generally when using a cutting torch the pressures are set around 60 o2 and 6 acetlyne and the oxygen in addition to supporting the flame is set high to blow the molten metal away. i dont beleive that the metal burns. the only metal i know of that burns that easy is magnesium.





also i may have not expressed my idea clearly i was thinking of sealing the intake as in using a carb hat and injecting into that.

Magnesium burns that easy because it creates its own oxygen. THats why it burns under water too, the oxegyn does burn the metal but not flame like. iT pushes so fast into the metal that its a tpe of friction effect I beleive. And the acetylene buffers it. Something like that. It works similar to the water jet saws, that have the diamond powder mixed in hte water. Im sure youtube has an explanatory vid somewhere.



And yes we hijacked thehell outta this thread. We should have a section only for hijacks where everyone hijacks everyone elses shyt. LOL

no,the acetelene is there to create the heat needed for the iron to combine quickly in a chemical reaction with the oxxgen.oxygen is fed at high pressure because that much is needed to support the reaction.the higher pressure allows sufficient flow,while focusing it into a narrow stream so the reaction takes place it a narrow cut instaed of over a wide area.to demonstrate this,try turning the acetelene off while the cut is going....as long as there is heat in the metal,it will keep cutting.how could this be,if the acetelene is needed to melt the metal,so the oxygen can blow it away.it's because the iron is the fuel,and it is burning with the oxygen to create the heat needed to support combustion.

Cutting torch
A cutting torch head is used to cut materials. It is similar to a welding torch, but can be identified by the oxygen blow out trigger or lever.

The metal is first heated by the flame until it is cherry red. Once this temperature is attained, oxygen is supplied to the heated parts by pressing the "oxygen-blast trigger". This oxygen reacts with the metal, forming iron oxide and producing heat. It is this heat which continues the cutting process. The cutting torch only heats the metal to start the process; further heat is provided by the burning metal.

The melting point of the iron oxide is around half of that of the metal; as the metal burns, it immediately turns to liquid iron oxide and flows away from the cutting zone. However, some of the iron oxide remains on the work piece, forming a hard "slag" which can be removed by gentle tapping, and/or a grinder this was copied from wikipedia......sounds a lot like what i just said in the previous post

wow i just learned something new.

 

[gwaii]

there's always room to learn new things......this one i am very familliar with,as i am a journeyman metal fabricator/welder with a background in chemistry,but when i am not sure of something,i find google is a good freind.
