Exactly what is "FORCED" induction?

[Se7en172]

As above all infomation appreciated.

 

[Fred@BTM]

exactly what it says on the tin, air is forced into the engine, rather than the engine sucking it in itself (imagine you breathing)

 

[182joe]

air is drawn into a bigger area then the air pushes it into a smaller area where the filter is.

eg. a funnel shape i believe where the air is hitting the larger end and the filter is at the smaller end.

 

[Fred@BTM]

^exsqueeze me?

 

[182joe]

haha i am struggling to explain it.

i know what i mean.

Forced Induction = Turbo/Supercharged

(I think)

 

[DrR]

Air is forced into the engine basically.

 

[osbid172]

Its like the difference between an SBD and really pushing it & letting one rip!

Doesn;t it have to involve a mechanical device (turbo/supercharger) to be forced induction? The 'funnel' concept applies to most airboxes I think, and some cars have a 'ram effect' into the airbox (197 included, apparently), but it's not classed as forced induction.

Forced induction is a term used to describe internal combustion engines that are not naturally aspirated. Instead, a gas compressor is added to the air intake, thereby increasing the quantity of oxygen available for combustion. This compressed air is normally referred to as boost or charge air

That's because it isn't forced induction....'ram air' induction trumpets etc are just marketing BS

So which mechanical part of this is going to 'ram' the air in? Please explain the difference between raming the air in and forcing lol

oh god, que 20 pages of "ram air" rubbish

 

[TheJesus]

oh god, que 20 pages of "ram air" rubbish

pmsl, was just thinking that

 

[mattjk]

what about if you had the butterly facing towards the flow of air without a filter surely at 60+ mph this would give some sort of forced induction

Edit: an also a fked engine of course!!

 

[Fred@BTM]

^nope

 

[Reyes]

Do we run faster if air is blown into us?

 

[mattjk]

It must improve performance though. Ill go and cut a hole in my bonnet and report back

 

[Fred@BTM]

^nope

 

[TRW1]

Unlikely....last time I was blown my legs went all jelly-like!!

 

[mattjk]

Oh. Okay fair enough What do I do with this hole now?

I think ram air works on a similar basis to underfloor aerodynamics (bear with me here) - The air coming in chanelled into a smalled space as it comes in, which speeds up the air flow, which then sucks even more air in.

Forced induction is when you have a spinning impellor/propellor that is then driving more air into the engine. Turbo's use exhaust gases to spin this, whilst superchargers are run by the engine itself.

I think this is about right, but somebody please correct me if I'm wrong!

Yep....here we go:S
