I'm having a discussion on another forum which is interesting

Is NoS (N20..Nitrous Oxide..whatever) 'forced' induction?

I say no as it doesnt affect the VE of the engine if I understand VE correctly. And any type of 'forced' induction would directly raise the VE.

Is this right?

 

Doesnt effect the VE?

I take it you dont know what nitrous is then

Yes its VERY much forced induction.

1000psi is boost in anyones view!

 

"The volumetric efficiency of a engine at a certain speed is the pressure of air/fuel mixture inside the cylinder when the piston has finished sucking in the mixture, as a percentage of the atmospheric pressure"

I didnt think NoS was directed directly into the cylinder.......i'm on about if it's injected into the plenium......

For it to affect VE then wouldn it have to affect the in cylinder pressure at BDC before the compression stroke

 

Ok mate, clearly you are the expert, PMSL

What would i know about nitrous after all, not like its my specialist subject or anything


Just one or two minor little thing you might want to consider though:

Its jetted inline with the air stream (sometimes with a little twist to aid mixture) imagine the pressure drop you get behind the jet when it comes out at 1000psi (and hence the extra air flow)

Its in liquid form when it enters the cylinder if implemented proprly, and then boils in the cylinder (what takes more space liquid or gas and by how much?)

 

Thats why I was asking Getting friendlier this place is by the minute

 

But i gave you the answer and then you asked again saying the opposite :S

 

I didnt say the opposite..I asked.

Thanks for the answer tho...i can see how the VE is affected.

 

Hope you didnt argue TOO hard on the other forum that it wasnt mate

 

Not overly hard but reasonably so.....roflol

I've just copied your response in tho much to my shame. I'm not proud

I was always taught to question stuff if i wanted to know something so dont think I was being funny above.

I was right with the basic idea that to be forced induction the VE would HAVE to be affected

 

Matt, fair play to you, im the same mate, i will argue my corner as long as i believe it but as soon as im proved wrong im huble as fuck and learn from it.

Only way to get anywhere in life
