Why not use pure oxygen instead of air or NOS to improve power, emissions and fuel economy?

Question

Edit: back in the early 1900's, the inventor of the Vespa Scooter used pure oxygen in his radial airplane engines to "try" and win a speed record. The dangers of pure oxygen could be reduced by using an "oxygen separator" similar to those used by medical patiens, so that only a limited amount of oxygen is on hand at a time. I am also interested in using pure oxygen in a "wood stove" so I dont have to open the flue up so wide. Again, for safety reasons, an oxygen separator could be used. I use lots of pure oxygen for shipping tropical fish and haven't burned any steel wool (not to say thats not a fact). And once a lady at the PO got concerned when I told her the fish in the box were insulated in a bag of water and pure oxygen. She worked for OSHA,

Answer 1

You have a good idea, but the internal combustion engine as we know it wouldn't last more than a measured seconds before it would blow you and every house down in a city block. Have you ever heard of the chemical solution "hydrazine". It's a highly unstable volatile chemical which manages to add oxygen to the a fuel before it enters the combustion chamber of a racing engine. It has been outlawed in every branch of motor sports today. It has killed people in the past. Each engine today is designed to get by with the lousy nitrogen oxygen uneven split we live in. Pure oxygen would fire well below the 25 - 30 degrees that we are tuned to fire today. Pistons yould melt in seconds, the valves would melt, the cast iron head would melt in seconds as well as the block rods crankshaft and of course the oil in the pan will have been long gone. Not the highest octane gasoline known to man could reduse the pre-ignition that has just happened.
Somday some one may do this in some form.

Answer 2

while pure oxygen is highly flammable, it offer nothing in the way of adding power. however, NOS is not flammable at all, but the difference is NOS is like "super cooled" and chills the fuel to a lower temperature which creates a more powerful explosion when ignihted by the spark plug. therefor, the more powerful explosion creates more horsepower and a cleaner result in the combustion chamber. the engine has to be specially built to accomodate for higher temps and stronger horsepower. needless to say, you can just put NOS on grandmas nissan stanza or the engine will not last long at all.

Answer 3

i did give you a star on this question as it is interesting but,
the ability to control O2 or nos with the present engine designs
are in the least, very dangerous. and as far as i know of mass marketing is concerned, most people know that o2 is very volatile, and with our present technology. people wouldn't right now
wouldn't want to be incinerated in a simple car crash.
with the question you posed, why not try to come up with an idea where this, the overall fuel issue, can be remedied.

Answer 4

NOS is just safer. For the amounts of O2 you would need it would have to be in liquid at about -400 degrees. NOS is non flammable, O2 vigorously accelerates combustion.

Answer 5

At 25% O2, steel wool will burn at room temperature. Do you really want something THAT combustible?

Answer 6

pure oxygen also reacts explosively with engine oil

Answer 7

oxygen isnt really that flamable

it makes flamable things like wood and paper even more combustable. so much that is seems like they explode.

Answer 8

pure oxygen + spark = Boom

Answer 9

oxygen is very voletal
