Poll: Bahrain Grand Prix 2022 - Race 1

[Mr Jack]

E10 combusts differently to “normal” fuel, so that hotter reaction will definitely catch people out this season.

Reading around, it seems that E10 has a lower combustion temperature than straight petrol but that differences in its combustion properties can cause overheating in some engines. This seems to be a problem only in engines that weren't designed for it, though, but on the other hand F1 engines are so extreme that maybe weird things happen. Who knows?

You have to fatten the air:fuel ratio a bit for fuels with alcohol in them - the stoichiometric ratio for non-ethanol petrol is 14.7:1, for E10 it's about 14.1:1. And of course you're very rarely running an engine like that, so WOT figures are going to correspondingly richer. Run it lean and you'll get overheating, same as any engine.

Interesting video on what might have happened to Red Bull:

Don't ask me I am not an expert, if the guy from Shell is saying it, I am sure it must have some validity.

The way Ferrari are performing, so far this year, I would say between them and Shell, they have got something right.

Brundle said this:

“I’d mentioned earlier in our Sky F1 show that few teams had done a hot run-out fuel test with the new E10 fuel; it's quite a difference when the remaining fuel gets ever hotter in the tank in the closing stages of a race. I know these things only because knowledgeable people tell me."

I think his sources are likely to be quite reliable tbh

The two things are completely different.

Yes as fuel in the tank gets hotter it evaporates more so runs out sooner.

However

As that fuel evaporates it cools things around it, exactly how high ethanol fuel is used to cool parts of engines.

So Brundle and his source, and the guy from Shell are both correct about very different things relating to the same property of ethanol fuels.

Indeed, so that explains how the comments made by the commentary team might have caused people to get the wrong end of the stick
