Suck Squeeze bang blow question!

No you won't. It'll still be 2 litres, just at a higher presure and temperature.

Hi, I'm back, just slightly slower than before.

Agreeeee with the above statement.

Junk all the other arguments. The engine will NEVER go anywhere near 4,200 rpm, I just gotta make sure.

So all I gotta do now is get my 4.2litre engine hehe!!!!!!!!!!!!

GWH - I was very concerned about pipe diameters too - good old pi.

pulse jet and ram jet are different things...

think you got a bit confused there!... Mr Hitler used a pulse jet.

Yep.

A pure ramjet uses forward speed and the shape of the inlet duct to compress the air before injecting fuel and igniting it. Pulse jets are superficially similar, but nowhere near as efficient.

depends when you measure the 2 litres...

2 litres is 2 litres, doesn't matter where or when you measure it.

The answer to you next question is .......

No, a 4.2 in-line six won't fit into your sheddy's engine bay.

As it will always be.

I think peeps are getting confused about volume, gases?

High pressure = massive potential volume, but still contained within a given volume. Scube tank f.i.

Ahhh, where's that plane on a conveyor when you most need it ??????

[MattF]

Density.

[Albannach]

If you take the 2 litres of gas that's pressurised in the engine, then expand it down to atmospheric pressure, keeping the temperature the same, the volume will increase (in which case it's not 2 litres any more). But if the temperature is allowed to decrease at the same time as the gas pressure is decreasing, it may not increase in volume.

Speak for yourself, you cheeky bugg4r lol

[Albannach]

Density.

Shhhhhh!

No, it won't.

Shhhhhhh..........

I think the Shed is about to be stolen and found burned out. HO HUM

If the pressure inside the engine when it sucks is zero, and the air pressure outside isn't markedly away from the norm, and the Turbo isn't boosting too hard and there is no super charger, and you allow for the fuel taking up some of the volume, then yes.

As long as the exhaust isn't too restrictive...

( I have been t'pub so am immune to any votes that may follow.)

So as we said, most of the above is FLAPJACKS!!!!!!!!!


The pressure inside the engine will at least be 1atmos. (Err, I think) But never ZERO.

ZERO pressure = perfect vacuum ) theoretically.

GWH - Discuss...........

i reckon the easiest thing to do would be to buy the thing and worry later !!


but by bernouillis equation,two volumes of gas at equal pressure,temperature and volume will contain an equal amount of molecules

p1v1t1=p2v2t2

as the pressure differntial woild be different inside the cylinder,its safe to say that the volume of gas may be similair but the temperature,and pressure are not

or

p1 does not equal p2 so bernouillis eqn is violated and the volume(number of molecules in each given amount of gas) must be different


right back atcha !!
