NOS confusion

[EF9_boy]

Is NOS forced induction or not?

 

[AHHVTEC]

no

 

[97hatch]

its a depateable topic but most say no and some say yes as you are forceing extra oxygen in the engine

 

[jamesA]

You're injecting extra fuel into the engine.

 

[Kanned]

no

A big fat x2 from me.

Nitrousoxide (NOS is a brand, dude) introduces extra oxygen into the chambers to burn so you can add more fuel and get a more powerful combustion, it's a great power adder if you don't use too big of a shot for your build or use it at low rpms. That's my opinion.

Oxygen :fr:

Nitrousoxide (NOS is a brand, dude) introduces highly combustible nitrogen into the chambers along with extra oxygen to burn, it's the perfect fuel and a great power adder if you don't use too big of a shot for your build or use it at low rpms. That's my opinion.

God damn it! NO NO nitrogen is a noble gas! It DOSE NOT BURN!

when nitrous oxide is heated it releses the oxygen atom. More oxygen in the same volume allows you to burn more fuel, More fule being burnt in the same volume equals more power.

If you stuff more oxygen into the engine, you have to inject more fuel in or you run lean. So don't call me a ricer, k thanks.

Yes! It is. You can believe what you want, but any sanctioned race event you go into with nitrous you be classified as "forced induction".

 

[double0Si]

I thought sanctioned events just classified it as a "power adder." In Pro Mods your allowed one "power adder"; Nitrous, Turbo, or a Supercharger. I'm not saying its either because I dont know for sure but I've never seen NHRA, IHRA, or anyone else call it forced induction.

Edit/Augmentation

From the Wiki...

In vehicle racing, nitrous oxide (often referred to as just "nitrous" in this context to differ from the acronym NOS which is the brand Nitrous Oxide Systems) allows the engine to burn more fuel and air, resulting in a more powerful combustion. The gas itself is not flammable, but it delivers more oxygen than atmospheric air by breaking down at elevated temperatures.

Nitrous oxide is stored as a compressed liquid; the evaporation and expansion of liquid nitrous oxide in the intake manifold causes a large drop in intake charge temperature, resulting in a denser charge, further allowing more air/fuel mixture to enter the cylinder. Nitrous oxide is sometimes injected into (or prior to) the intake manifold, whereas other systems directly inject right before the cylinder (direct port injection) to increase power.

Since nitrous allows a much denser charge into the cylinder it dramatically increases cylinder pressures. The increased pressure results in heat, and heat will cause many problems from melting the piston, cylinder head or valves, to predetonation.

After reading that, Im leaning on forced induction. I know Wikipedia can only be taken at face value since its user edited but it sounds correct to me.

im going with forced induction..
just due to the simple fact that you need bottle pressure for the nitrous to work effectively..what is pressure??? FORCE,,whats happening??? its being INDUCTED...

 

[K2e2vin]

I don't drag race But yes, "power adder" is the same thing as "FI"; as in all instances you're forcing more air/oxygen than the engine would normally pull in on it's own.

Damn thanks for the correction, post edited.
