oxygen injection

[Jculler1610]

I was wondering if injection oxygen gas into maybe the intake it self or before the TB would help any thing. I think, tell me if I am wrong, taht it is oxygen taht is used from the air to fuel the combustion in the cylinder. so I would think more of it along wiht maybe the addition of maybe propane or just more fuel would increase HP.

RE: oxygen injection

Works great, but totally will melt the pistons... Atmosphere is 21% Oxygen, 78% Nitrogen and 1% other, mostly Co2. Injecting pure oxygen, even at atmospheric pressure WILL yeild about 5 times as much power, given you add the appropriate amount of fuel. The problem is, the combustion temperatures will be SO high that the oxygen will not only burn the fuel, but it will oxidize or burn the valves, pistons rings and chambers just as well. Its the quantity of nitrogen in the atmosphere that keeps the combustion process somewhat stable. You probably could get away with small quantities, but it would still take its tolls on the engine. Nitrous Oxide is the correct answer to this question. It is about 70% oxygen, and contains the nitrogen to stabilize combustion to an acceptable level to keep pistons, valves and rings from burning up. But even still, people routinly blow there engines from these symptoms anyway due to improper fueling and too much nitrous.

In short, Nitrous is the answer. Oxygen is just WAY too strong.

Re: RE: oxygen injection

It is about 70% oxygen

Wouldn't it be the other way around (about 70% nitrogen)?

Im an Idiot.
N²O not NO²

Right...

It sounded good when I read it.

I always wondered why N2O was used instead of pure oxygen.

How about Hydrogen? There's a guy here at work that swears it'll work and save gas. Even showed me a website that sells Hydrogen injector kits that tap into the intake manifold.

I would think that it would be too hot, similar to Oxygen, what do you guys say?

Well, since ford has already converted cars to run on straight Hydrogen gas I guess it would work. Too bad they are wasting their time with the internal combustion engine. They should investing more into fuel cell technology.

Your biggest problem with Hydrogen is blowing up. Get to much and your engine will go up like the Zepplin. But i haven't heard of someone mixing it with Gasoline. Thinking about the chemistry, you would create some forms of NH, most likely ammonia (hopefully your seals are new) and some water if you didn't burn off all the oxygen. Plus the burn rate and spark issue of Hydrogen burning much easier than Gasoline might be an issue.
From a money stand point you would probably be better of reworking the engine to run off 100 Octane test fuel (good ole Prop Airplane stuff) and make a big ram jet for air to get into the engine.

[93Oldsdroptop]

I dunno, that's why I asked. This guy has a F-150 Ford pickup that he wants to hook this Hydrogen generator up to. He's desperate to increase his gas mileage.

[Fierobsessed]

Hydrogen and gasoline are simular. Both need to consume a stoichiometric ratio of oxygen to fuel. Hydrogen and gasoline have the same characteristics when run through an internal combustion engine. The only differences is, when you react hydrogen with oxygen you get water. or an excess of one or the other due to combustion innefficiencies or a mixture deviating from stoich. Witch also applies to gasoline as well believe it or not. It can only put out water, and carbon monoxide. If the air fuel ratio is off or there is combustion innefficiency, witch there always is then you will have an excess of either of the prime ingredients, oxygen or hydro carbon (gasolene) or Nitrous oxides from the nitrogen and oxygen in the atmosphere due to excessive combustion temperatures (correct me if I am wrong)

But yes, I have to agree that gasoline engines, and internal combustion engines days are numbered. Americans didn't care about efficiency till 2 weeks ago. So NOW we are all feeling the pressure to make Super efficient, and inherently low emmission cars. Watch a car commercial now you can bet gas mileage is the focal point. The conditions are just right now to breed alternative fuels. And I hope someone comes up with something to relieve us of our oil needs.

Fuel cells are one promising answer. The efficiency is more then double, and they have practically no harmfull emmissions. They can be run on gasolene, hydrogen or whatever else you so desire. I'd be willing to invest in any company that is pioneering research in fuel cell technology. Best part, is that they put out electricity, witch we have nearly mastered using.

[Lyle's GTP]

Yeah, and Hydrogen is the most abundant element in the universe. So, as long as we can use electrolysis to derive hydrogen from water we are all good. The most promising method's to produce this electricity for electrolysis are Wind, Solar and Nuclear. Nuclear being the most popular choice because the efficiency of the reaction can be increased by using the waste heat from the reactor to raise the temperature of the water.

Appartently Korea is building a nuclear hydrogen plant that will produce 5 times more hydrogen in a year than the world uses anually.

fuel eff. in gas engines can be incresed by building the motor for your use an gearing i like natural gas or popane if you raise the compression it gets effience because the octane is higher but most conversions leave the motor alone an this is not a good use of propane or natural gas got to build fgor the use. this is just my way of thinking. 23mpg 78 gmc 3/4 ton van lt1 an 4l60e race van.

[Lyle's GTP]

That's all good. But even theoretically speaking, a internal combustion engine could never come close to a fuel cell for efficiency.

Lyle

[Husky]

How close will a Fuel Cell come to a Traditional engine for performance?

[Lyle's GTP]

Sky is the limit. All the fuel cell does is provide electricity. Then you couple that to an electric motor. Which are extremely efficient, have very few moving parts and can be built to run to revs that are limited only by their bearings.

I would say that you could have a perfectly flat torque curve through the entire RPM range. As far as power is concerned, just like conventional engines, it just depends how much money you have.
