How does nitro boost work?

Question

Hi, people. :) We've all seen movies such as The Fast and the Furious, where tuned cars use boosts of bottled nitrous oxide gas for added acceleration and top speed. What I'd like to know is just how it works. I've heard that it basically consists of cold gas being injected into the engine, presumably to cool it, but is it involved in some kind of chemical reaction?
Thanks!

Answer 1

Nitrous oxide is most commonly made by fusing and "boiling" ammonium nitrate to form steam, nitrous oxide, nitrogen, ammonium nitrate 'fog' and small amounts of very toxic higher oxides of nitrogen; (NO2, NO, etc):

NH4NO3 → N2O + 2H2O, ΔH = −36.8 kJ:
The addition of various phosphates favors formation of a purer gas. This reaction occurs at around 240°C, a temperature where ammonium nitrate is a moderately sensitive explosive and a very powerful oxidizer. At temperatures much above 240°C the exothermic reaction may run away, perhaps up to the point of detonation. The mixture must be cooled to avoid such a disaster. In practice, the reaction involves a series of tedious adjustments to control the temperature to within a narrow range, which it will not naturally tend to stay in. Professionals have destroyed whole neighborhoods by losing control of such commercial processes.

In car racing, nitrous is sometimes injected into the intake manifold or inserted before the manifold to increase power: even though the gas itself is not flammable, it delivers more oxygen than regular air by breaking down at elevated temperatures, thus allowing the engine to burn more fuel and air. Additionally, since nitrous oxide is stored as a liquid, the evaporation of liquid NO in the intake manifold causes a large drop in intake charge temperature. This results in a smaller, denser charge, and can reduce detonation, as well as increase power available to the engine.

The same technique was used during by World War II Luftwaffe aircraft with the GM 1 system to boost the power output of aircraft engines. Originally meant to provide the Luftwaffe standard aircraft with superior high-altitude performance, technological considerations limited its use to extremely high altitudes. Accordingly, it was only used by specialized planes like high-altitude reconnaissance aircraft, high-speed bombers.

One of the major problems of using nitrous oxide in a reciprocating engine is that it can produce enough power to destroy the engine. Power increases of 100-300% are possible, and unless the mechanical structure of the engine is reinforced, most engines would not survive this kind of operation.

Answer 2

the way nitrous works is actually far different than most people think. Its not more explosive than gas, it doesnt do much in the way of cooling the air coming in (although it does some), etc etc.

its actually NOT a cold gas. its usually warmed up in reality. it does cool down on being injected into the engine because of the rapid increase in volume/decrease in pressure

the way it works is this: nitrous when broken down at heat gives off about 30% more oxygen than is in the air (which is mostly nitogen), so your just adding more oxygen into the intake, for which you can add more gas and boom, more power. The difficult part about it is retarding the timing so you dont start pinging like crazy due to all the extra power.

its very true u can definitely have a nitro boost in ur car it will cost u around rupees 2 lakhs and if ur a starter i suggest u to go for a turbocharger it also provides speed and it cost less then no2 (nitro booster) it will cost arnd 1 lakh and all this is very much legal morover no one checks ur cylinder in mumbai i have turbo in my lancer and i have participated in many races i know many shops in mumbai where all this is done maximum are in andheri

Answer 5

in nitro booster bootle the chemicals are filled with high pressure andso when the button is pressed the gas is realesed and the bike/car talks to air.
u can take xample of perfume which is nothing but high pressurised gas

Answer 6

It cools the cylinder when injected preventing pre-detonation thus creating a more accurate ignition of the fuel entering the cylinder. That is as simple an expanation at it gets.

Answer 7

ok now let me tell u u wanna do it in Esteem but i think it would be foolish ness the car should be a bit srong for that like a mitsubishi lancer one of my friend has got it fitted in his mitsubishi lancer and that car just shoots like a bullet. . .he got it done at Pune. . . .and even i watch the same episode of men maange more its cool
