First Nitrous now Co2, what next?

[spy604]

water in Co2? as far as i knew, co2 only has carbon and oxygen, it takes a little hydrogen to make water. maybe you mean condensation, well your not adding any water, so either the water in the air will go in the engine as vapor or liquid, it reall doesnt much matter, it still goes in, albeit in small amounts

[tparrotte]

what would happen if CO2 was injected into the intake?

[integra818]

Colder intake charge, but too much would be bad for your engine. You don't want the inside of your engine to be very cold, it won't work properly if it is. A little bit of cryo in it might get you some HP

CO2 is extremely easy to find....if there is a local paintball place you can get CO2 filled there...there is a place called LP gas in my town that will fill anything from propane (their main sales im sure) to CO2 to NO2 to Helium....its quite cheap too since they are industrial and not commercial sales....

What??? Do you know any physics at all?

Considering the fact that CO2 will not burn what will happen is:

small amount: performance loss
large amount: engine will die

umm Co2 is extrenky cheap, i used to play paintball all the time and Co2 was about 10 cents and ounce. But that was being filled at a paintball shop, if you take the tank to a Co2 dealer who does commercial C02 its going to be more like 3-5 cents per ounce.

i was thinking....why not inject hydrogen and oxygen into the engine....talk about some horsepower gains....lol

Because the engine will blow up perhaps?

CO2 is used in some fire extinguishers, it's also common as a protective gas for welding.

i was kidding...did you actually think i was serious...LMAO

BMW inject hydrogen, their cars have been able to take it since the seventies... but thats BMW....
(b4 comment i realise that this is subject to specialised injection etc.)

I'd say that the CO2 thing would work a treat particularly if you have a small intercooler, I have an MR2 so intercooling is hard and i'm gonna get the co2 system, but you have to be careful about where your intake is, you don't want the co2 to get to the intake or youll lose more than you make. My intake is on the opposite side of the engine bay with a big air scoop in the side of the car so i can use it no probs...

Using hydrogen as a fuel isn't a problem, but today there is no gain by doing it as the hydrogen usually comes from crude oil.

The problem for an engine is when you start to inject pure oxygen, the temperatures, combustion speed and pressures will go sky high. Dirty feeding lines for the oxygen is enough to start a fire.

[TRD2000]

short term perhaps... long term hydrogen will be good. still means you use the oil but at least you're not churning out CO2... depends what the rest of the oil gets used for.

[CBFryman]

there is a problem with using hydrogen as a fule...it is extremely volitile and very reactive...meaning that inorder to keep the cars safe and the fule good you have to have extremely expensive fule cells....and fule delivery....its been done...the exaust is simply water and nitrogen, but pure hydrogen is not a fun thing to play with....think about in the event of a crash and the fule cell gets punctured... i know there are already cars that used hydrogen...ill stick to my hydrogen combined with carbon to be a bit more stable...

[TRD2000]

you obviously haven't felt the effects of global warming. naa but seriously, i see it as a great future fuel, and its great for the environment, but it will be extremely difficult to implement, so it won't be in popular use for a while, hopefully before fuel becomes too expensive!

[CBFryman]

^^it hasnt been proved that there is global warming or that any of the human activities have caused the few holes in the ozone layre...it is simply green peace thory...AKA liberal BS....the earth goes through long cycles of cold and hot...IMO we are just reaching a hot right around the time that cars become popular...the holes havent gotten any smaller since more people started driving civics and corolas...besides...by the time it has any major effect ill be long dead and so will my children and more than likely my childrens children so... why should i care? and just to let you know plants absorb carbon dioxie and carbon monoxide so as long as all trees that are cut down are replaced then we have no problem there...if yo ucant stand smog stay out of a big city....your never going to have super clean anything when yo uconcentrate lots of humans togather in a place where nature cant clean up after us...
