Formula One leading figures and the Strategy Group teams have agreed a on a raft of regulation changes to revamp the sport, attempting to bring back some of the speed lost in recent overhauls.
You should ask Gordon Murray on how to do it.SectorOne wrote:
Sticking a hose on it and pump 50kg´s of fuel in 2-3 seconds while changing tires is just bad news.
The only way i see that is possible is with some sort of canister system where you simply take off the empty one, lock into place the new one.
But teams wont put a 50kg fuel tank in their car IMO. They will opt for a 75kg cell instead, for more flexible strategies...bhall II wrote:The refueling ban is inconsistent with F1's recent push toward efficiency, because it doesn't make any sense to carry the fuel needed for the last lap of the race from the first lap of the race. This is doubly so when you consider that each (unavoidable) pit stop ultimately represents a missed opportunity to make the cars that much lighter/quicker/more efficient.Manoah2u wrote:1. because if we're gonna introduce refueling in a 'green f1 format', then how do you explain the implemention of the fuelling ban either way? why impose the fuel flow restriction before then?
...this is just dumb.
Of the many knock-on effects of refueling will be the end of grotesquely long wheelbases. That will make chassis lighter, stiffer, cheaper, less sensitive to aero changes, and easier to set up.
And since there's a very strong correlation between wheelbase and directional stability, the cars will be more nimble and more difficult to drive as a result of reduced stability.

In short, I think this is the best change F1 has made in a looooooooooooooooooooooooooooooooooooooooong time.
They probably could, though I believe there's only ever been 2 recorded incidents of this. Plus, that doesn't account for tampering (like that that caused the beneton fuel fire).Vary wrote:About the unsafe release when refuelling: couldn't they implement a sistem that prevents the engagement of first gear when the pipe is still attached?

Just before refueling was banned, and in response to Massa's incident in Singapore, the pit lights used by some teams in lieu of a "lollipop" were generally equipped with a feature that prevented a green light until after the fuel nozzle was removed from the car. Eventually, they were programed such that the green light was triggered directly by that action (unless overridden by the "lollipop man" due to pit lane traffic).Vary wrote:About the unsafe release when refuelling: couldn't they implement a sistem that prevents the engagement of first gear when the pipe is still attached?

I suppose from an engineering point of view that could do lots of things. One of my contentions with the way F1 handles refueling is that in the past they allowed the teams to develop their own refueling systems.

The refueling rig used before the ban was a standard item made by Intertechnique, an aircraft fuel system manufacturer. These generally performed safely, at least when the teams did not tamper with them to increase the fuel flow rate (as in the Benetton 1994 fire).Moxie wrote:I suppose from an engineering point of view that could do lots of things.

IMHO whatever system used should be one that is owned and maintained, and frequently inspected by F1 and that all the couplings between car and fuel rig standardized, and the whole system tested throughly before introduction. Frankly I believe that flow rates should be limited by gravity and atmospheric pressure. Of course this will make pit stops linger, but isn't on-track racing the point anyway?

This is downright scary, it would require high pressures to force any respectable amount of fuel into a tank. High pressures and gasoline is a recipe for disaster.SectorOne wrote:Toto´s words on the refuelling.

Refuelling was banned because of cost and because the pit stops were taking too long. But we want to re-explore it and see if we can make pit stops for fuel and tyres happen in the same time it takes to change the tyres now - two to three seconds.
"We have agreed to explore this avenue and the cost involved because it could be spectacular. If it's too expensive, we won't do it."

If you´re talking about the canister system my idea would be gravity fed so no pressure in the canisters.DaveKillens wrote:This is downright scary, it would require high pressures to force any respectable amount of fuel into a tank. High pressures and gasoline is a recipe for disaster
