Quote from axus :I guess you could save £2 over your entire life doing that.

With prices as they are nowadays, I bet it would be more than that.

As they say..."Look after the pennies, and the pounds look after themselves".
Quote from Bean0 :The way I see it, it's the same reason as for colder air.

The injectors fire a set amount of fuel each time they open, if the fuel is colder then there will be more fuel particles in the same volume...more dense.

Yeah, but injectors are typically calibrated to deliver a certain mass of fuel rather than a volume.

Quote :The ECU should be able to tell that the engine is slightly overfuelling compared to what is was expecting, and draw more air into the cylinder to compensate. This would give you more BHP at the same RPM than with warmer fuel.

You've got things backwards here, it's the amount of air going in which controls the fuel, not the other way round. If the engine detected overfuelling it would back off on the fuel injection. That said, I doubt there's any sort of closed-loop fuelling control on an F1 engine. From what I hear, they run crazy rich.

Quote :Could be wrong, but it seems sensible to me

I work with engines all day long

Quote from mikey_G :Dont forget that statement was made by Mike Gascoyne, who is a twat. So take the 5-10 bhp increase with a grain of salt.

Eddie Jordan said it too...
Maybe it's just lowering the overall temperature of the mixture. In this diagram if T1 is lower the area enclosed will be bigger. That area is the energy output of a four stroke cycle.
Quote from DeKo :incredibly stupid moves. Obviously its fine in karting, you dont get a tow or anything and its the onyl way to overtake. but with multi million pound cars with championships on the line its incredibly daft.

the same incredibly stupid moves that ensure a rookie beat the 2xWDC in the same car? That's racing. That's why Hamilton is there and you, and I are not! Have you ever been a to a professional kart meet. Maybe you should hop up to Wigan and watch the FREAK loads of tow you get down the main straight! Maybe you should do this before jumping to quite clearly 'pulled out of the air' assumptions.

On a side note. Alonso was beaten by his team mate in the same car. lol how mad is that. He even had a fair play official in his garage!
Quote from J.B. :Maybe it's just lowering the overall temperature of the mixture. In this diagram if T1 is lower the area enclosed will be bigger. That area is the energy output of a four stroke cycle.

I had thought about that, but the only reason the temperature rises from T1 to T2 is cylinder compression (isentropic compression in that chart), so any drop in T1 should be matched by a drop in T2 and T3, T4, etc... Well, not quite matched, but the ratio of T2/T1 and T3/T4 should be the same. The difference T3-T2 is given by the fuel burning and, unless you've got more air in the cylinder, this will not change.

I think that's right...it's been a while since I've looked at T-s diagrams Actually, the area inside the curve on a T-s diagram doesn't give you the work output anyway...you're thinking of a p-V diagram The work output from the T-s diagram is effectively equal to cp(T3-T4) - cp(T2-T1) (technically it's (h3-h4) - (h2-h1) on an h-s chart, but for an ideal gas h = cpT).

The only thing I can come up with is that the cooler fuel drops the combustion chamber temperature slightly and therefore allows a higher mass of air into the cylinder during the intake stroke.
Quote from SamH :Who in the world could gain from doing such a thing to Hamilton's car??

Ron Dennis.

Judging from the way you see that shitty pass of Hamilton, the only thing that keeps you alive is the fact that you race in karts or sims.
Quote from Albieg :Judging from the way you see that shitty pass of Hamilton, the only thing that keeps you alive is the fact that you race in karts or sims.

that makes no sense.
Yes, it makes sense. You got penalised 3 times on CTRA and you keep repeating your mantra about how to race, each time drawing more criticism and annoying more people who like heated debates and races but dislike boring brats. A lot of people disagree and a lot of people wouldn't like to race with you here. You're unable to have a sound judgement in this forum and you don't want to listen to other people's opinions. Even in a track you're not alone, and I suspect you would have the same attitiude thinking you're always right. Why don't you shut up and listen instead of repeating your mantra like a broken record? Show me you have a brain and two ears.

HHmmm... when someone pulls a move in an F1 car that I fully endorse, and

1. Doesn't get penalised
2. No one in the F1 world moans about
3. Rubens didn't seem to be reaching for the 'Vote Ban' button

and also whem most of you said previously that 'karting' moves like that 'couldn't be done in a F1 car'... I think I understand my position fully... Hamilton PROVED you lot have a very limited view of what is possible....

If you accuse me of being a broken record, surely ur response is a predictable, and repetitive as mine!
Quote from Intrepid :the same incredibly stupid moves that ensure a rookie beat the 2xWDC in the same car? That's racing. That's why Hamilton is there and you, and I are not!

Hamilton's move to overtake Barrichello was awful. Relying on the other driver to get out of your way and not cause an accident is a very bad way to go motor racing. I don't care what Hamilton's credentials are, it was a ludicrous move...he was very fortunate that Barrichello saw him coming.
Quote from Intrepid :I think I understand my position fully...

I do too. That's why I think you shouldn't be here.

huh.... are you serious.... are you actually being serious....??? your joking right!!!! wow....

I have always said good close racing requires two observant minds... and Rubens experience was very valuable in that move.... but that's racing... that's HOW IT IS DONE....

Fortune HAS NOTHING TO DO WITH IT. Luck wasn't an issue. Rubens is a smart observant driver... that's just a fact.

Man you guys wouldn't last 5 minutes in any real race team with that attitude.... you would lose all you sponsors within 5 minutes....

"sorry Mr sponsor but I didn't want to overtake him because I couldn't get significant overlap before the half way point of the straight"

"well say goodbye to your race car mate.. I am gonna go and sponsor someone else who actually wants to win races!!! ....."

It's how I lost my money back in the day.... because I was too pussy... I would fully admit that... that's how I learnt

Quite right, even the commentators were saying that he only did it because Rubens is old and wise, and that trying it on someone with less experience would most likely end in disaster.

You get the same in LFS, the more you race alongside a particular driver, the more trust you have in them (and vice versa) and both of you can get away with more risky moves than you would normally try in a public race against people you have no knowledge of.

That's why I added the "maybe". Was too lazy to check if I even knew what I was talking about.

Had a closer look now: Lowering T1 will lower T2. This means the area will stay more or less the same if T3 and T4 also drop. But if we could still reach the same T3 as before we would gain power. But which parameters define how high a T3 is reached? Is it the engine management that detects knocking? I don't know.

Quote from StewartFisher :
Actually, the area inside the curve on a T-s diagram doesn't give you the work output anyway...you're thinking of a p-V diagram The work output from the T-s diagram is effectively equal to cp(T3-T4) - cp(T2-T1) (technically it's (h3-h4) - (h2-h1) on an h-s chart, but for an ideal gas h = cpT).

I also checked this and it works for both p,v and T,s. Which doesn't mean your expression is wrong though.
Quote from J@tko :And surely the petrol will get closer to air temperature during a race anyway?

Perhaps they factored this in and deliberately made the fuel colder so it would warm up to req. temp during the race?

This is the sport in which the top teams refuse to use stickers for sponsors (like the "cheaper" teams do) and use paint to reduce drag - i think if they could get a 0.000000001 hp advantage they would...

AFAIK, the measurements were taken from the refuelling rig after each stop.

The lower temperature could easily save them pitstop time, either by putting in more in the same amount of time, or by taking less time to put in the same amount.

Not really.
I thought you wanted to setup the server...who is this mystical 'him' ?
How many people post under that account ffs?

Probably, but the fact that only McLaren filed an official complaint tells me that this could be a widespread and well known practice, and just a team is trying to gain some advantage from whistleblowing. The whole paddock, as I reported yesterday, was in a bad mood (except for McLaren), so it looks like someone went too far.

Make your own forum too, please.
a separate forum for different opinion to yours..??. interesting... I thought forums were about debate and opinion... but yh i like your way of thinking...

what makes a good forum...? everyone agreeing... yh that sounds really interesting...

Yawn. Again. No, a forum is a place for debates. I suspect you don't know what a debate is. Get a dictionary, you badly need it.
I have now followed the discussion for 8 pages and Intrepid i think people are just sick of your double-moral (you have that word in english?)
Want to penalize certain teams for irregularities but wanting to save your favorites from penalties.
Thats the problem people have with you not your opinion.

I think the only thing FIA could do is earasing the team-points to make the decision fit in other past decisions, but as it seems its common thing with the temperature, it think nothing will be done.

I have to say i was cheering with Hamilton in the race but when i saw he was far to nervous, i said to myself its maybe a year to early for him to win the championship.
Great performance from Ferrari and Kimi that season therefor the right champions.

If you were any good, you'd be racing and winning. Instead you run a shitty clone of karting.co.uk and teach youngsters how to kart. So, judging by your posts, your awful online record, and your driving ability in real life, I'd say you know shit.

Hamilton's move relied ENTIRELY on Barrichello getting out of the way. Bearing in mind the Honda is, what, 3 seconds per lap slower, and Barrichello wasn't going to defend anyway, it was a pretty stupid move. But then you seem to think any pass in F1 by Hamilton must be awesome - maybe you just have a lower IQ that you look (which is already pretty low).

Anyway, in short, you clearly know nothing about F1, racing or LFS (and you can't even be bothered to buy it!!!!).
