Talk:Nitrous oxide engine

message: I rewrote most of the text, as well as some adding some wikification.  This page still needs work, but it's at least more readable than before. Caveat: I'm no expert on this subject, so someone who is had better take a look. A picture would be nice, too. Khaydarian 01:51, 8 Jul 2004 (UTC)

message: The compound is nitrous oxide, not nitrous.  When a search is made for nitrous oxide, a disambiguation list should appear for the correct choice instead of creating this section with an incomplete name. --MartinezMD (talk) 04:41, 11 May 2008 (UTC)
thread_title:  "Nitrous" 

message: A section about when Nitro was first used for car tuning (counjoring up images of some uptight upper class person in 1908 going "One has got NOX, dont you know"), when it first appeared in racing, and when it first became very popular on the modification scene (i'm presuming after The Fast and the Furious came out) might be good 86.158.27.179 (talk) 21:33, 19 December 2007 (UTC)
replies: text: It was first noted in German war planes during WWII, but I don't know enough of the history to do it right. --MartinezMD (talk) 04:41, 11 May 2008 (UTC)
replies: text:  It was used in the modification scene decades before The Fast and the Furious came out.  It was popular in the Daytona Beach Road Course back in the early 1900's when they were going upwards of 200MPH on the actual beach in one mile.  Please do not use The Fast and the Furious anywhere in the history section, it is absurd.  —Preceding unsigned comment added by Erick880 (talk • contribs) 08:06, 11 May 2008 (UTC)
replies: text: It was used before WWII by a few racers, but the only cars doing over 200 at daytona then were the land speed record attempts. Some averaged over 200 in the "flying mile", but the few I'm aware of used conventional aircraft engines with 2 or 3 powerplants to the vehicle. Do you have any references? I'd like to know just how early it was first used.Ion G Nemes (talk) 04:49, 27 January 2012 (UTC)
thread_title:  History? 

message: Is this what some people commonly refer to as "nitro"? What is the legallity of it? Do professional racing divisions use nitrous, such as Nascar, or is it not permitted in certain racing leagues? How about street-racers -- are they allowed to use nitrous? All of these things need to be addressed in the article.
:No, Nitro means Nitromethane, a different type of fuel. -Sprintstar 11:10, 20 September 2005 (UTC)
thread_title:  Nitro? 

message: There are three possible mechanisms to account for the increase in horsepower associated with adding nitrous oxide:
# Combustion of the nitrous oxide itself.
# Extra oxidant allowing more fuel to be burnt.
# Charge cooling.
N20 has relatively little energy of its own to contribute to the combustion process, so the first option is not considered to contribute much power.  The second option is the most popular.  A reasonable assumption given the popularity of nitrous oxide in rocket fuel.  However, charge cooling has been shown in testing to provide just as much, if not more, horsepower than the extra oxidant effect.  The N2O expands as it joins the air/fuel mixture, this expansion cools the air, the resulting mixture is more dense, you can fit more in the combustion chamber, more fuel burns per stroke, and you make more horsepower.
Just a little bit I remembered from my internal combustion course.  Feel free to add / modify / summarize / ignore.

replies: text: As I have understood it for some time, mainly from the motorcycle tuning world, the charge cooling effect is by far the greatest factor in nox tuning. The claim in the text that running with nox allows "an oxygen saturation of 33% to be reached" is pretty disingenuous, as it assumes that only nox is injected along with the fuel. This is obviously never the case, as it is only at elevated temperatures that nox releases oxygen gas. Hence, an engine with only nox going in with the fuel would fail to ignite at all. If the charge cooling effect were tried with an inert gas then the partial pressure of oxygen would be reduced and so although you may increase the volumetric efficiency, you kill the combustion efficiency. Any coolant gas has to at least maintain partial pressure, and nox actually raises it... slightly. This results in the "nice balance" that Dustyattic identifies above. Unfortunately, my old tuning manuals and such went the way of the dodo quite a few years ago, so I can't unearth a ref to that effect. Pyrope 16:03, 14 May 2008 (UTC)
thread_title:  On the Physics of Increased Horsepower from Nitrous Oxide 

message: This page states that Nitrous increases power output by like 45%, while the Nitrous Dioxide article says it produces 100-300% more power causing many engiens to break down.
Which one, then?
This one is correct. --Mistertbones 17:19, 25 March 2006 (UTC)

message: I think we should call it a spraybar plate because a wet single-point system is usually a plate system.
That's not really true. Most single-point systems for EFI cars use a nozzle, not a plate. I'm thinking that we're better off discussing plates and nozzles separately so as not to confuse the issue. Also, please sign your comments with four tilde characters so we can keep track of the discussion. Thanks! Spinolio 17:40, 26 July 2006 (UTC)

thread_title: law

message: How about some discussion about the effect on engines of nitrous use?  One thing I've wondered about is using nitrous in a non-racing context.  Consider that many cars carry around a V-6 or V-8, but in 98% of street driving a small four cylinder would be enough.  Could a nitrous system be installed just for when that oomph is needed, to improve overall mileage?  Or would it kill the engine so quickly that rebuilds would swamp any possible cost savings, or would it be illegal under anti-pollution laws?
One of the problems with that idea is that nitrous is expensive.  Retail costs can go as high as $5 a pound.  It takes .8 lbs of nitrous to make an extra 100hp for 10 seconds.  So as you can see, it would get fairly expensive very quickly to use it for daily driving situations.
Actually, I think the guy has a point. The cost of producing nitrous oxide gas is actually a lot cheaper than what you pay for it at the NOS dealer. Perhaps if nitrous injection systems became common place, the costs would come down. Not sure about pollution though; N2O is a potent greenhouse gas. What actually comes out the tail-pipe when it is combusted though? Sir Spike 18:24, 15 June 2007 (UTC)

thread_title: Bit of Humor

message: The legal section is too vague and too US specific. It only mentions two sports bodies, both US, and doesn't mention the FIA (The biggest Motorsport body in the world) or Formula 1 (The most popular motorsport by viewing figures). N2O is street legal in the UK and I belive (Though don't know for sure) its legal to have the bottle open on a public road, though it might not be and you could probably be done on oter charges.(86.31.188.11 (talk) 01:44, 27 September 2008 (UTC)
