Hi! I'm a physicochemist and such processes aren't uncommon for me. That's why I was very surprised with hearing that story. The 10 degree difference rule seems awkward to me. There are plenty of reasons why - innaccuracy of ambient temperature detection, probability of rapid changes in ambient conditions that may cause deviation from the limits. Also, to punish the team it should be proved that they deliberately broken the rule, so it should be proven that they intentionally cooled fuel to illegal temperature before the race. As I said before in my mind there should be proposed absolute temperature limit for the fuel temperature.checkered wrote:I did some further
digging about how fuel is handled etc. and interesting details emerged. Small deviations from acceptable figures aren't that uncommon (especially in highly variable conditions) and it is highly likely that such events have been registered at many races during the season, but no action has been taken thus far. Is the FIA to open an investigation to all the races of 2007 while they're at it? That would certainly yield surprising results.
Fuel is handled by the teams in containers that hold 100 kilograms each; such an amount takes a certain amount of time to cool/warm up and we're dealing with a flammable substance prone to evaporation, too. There is a lag when changing the temperature throughout the mass and sometimes there's not enough time to get the figures exactly right. The containers are cooled down to a specific temperature in the morning of the day of intended usage, but I didn't quite get how that figure is determined. With a weather forecast?
Weren't there people here who work/have worked for F1 fuel suppliers? I think so. Hopefully they can corroborate or discredit what I've found and elaborate on what is being discussed here. It'd be a great help, to get to the bottom of this. Everything I've read thus far suggests (well, to me at least), that McLaren's inquiry will get nowhere as far as the results from Brazil are concerned.
