2010 Engines, Fuel Consumption & Possibilities

[Astro1]

With no refueling next year what are everyone's ideas on how teams and engineers will cope?

Teams will want to run engines as lean as they possibly can but without overheating etc etc.

Power implications with different AFR (air fuel ratio). Higher AFR, more power, more heat more prone to ping. Lower AFR less power, less heat less prone to ping and more safe.

I think that cooling will play a huge role next year as teams will be able to should they need to, lean out their engine past an acceptable norm to eek a few extra kilometers out of their fuel.

With the engines frozen for the most part, cooling will be the major area to exploit.

I think that the Ferrari engine which for example has shown to be hungrier than some may be because it runs more rich than others to keep combustion temps and in turn engine temps in check.

teams will make as much power out of the engine as possible and make the tank big enough to get them to the end. The extra HP will be worth the fuel weight

maybe a lean burn limp home mode but nothing more than that

There is also the question of a safety car period. In that case you also need a "let's waste some fuel" mode as well?

Running behind a safety car is a sure opportunity to loose some weight. No?

Wouldn't you conserve fuel to give you more to use at race speeds!?

depends on if you already have enough to finish the race a full rich, if you do then you definitely want to drop some fuel

The power difference between a full rich and a "full lean" is not more than maybe 30hp(less than 5%) with today's engines, the teams will find a balance between the weight of fuel, reliability, the aero cooling penalty and the difference in power, and will moniter the temps & the pace during the race and adjust accordingly.

I doubt any of the teams will adopt a full rich race strategy as you think, the weight & tire wear(pit stop) penalty would be just too high.

And if history is anything to go by, the teams did not adopt the full rich strategy that you propose in the past when refueling was not allowed.

I never said full rich I said peak power. Or maybe you are referencing some one else.

I am hoping for the afterburner map to burn off extra fuel during safety cars.

full rich is peak power(for the most part)... any extra is just dumping fuel either to cool or to drop weight

I was thinking full as more over rich def. not peak power. If you are taking soch. to be full rich then yes I guess I did mean full rich.

I'm thinking some team will come up with a more novel way to dump fuel than just run rich.

[Scotracer]

I think getting rid of fuel will be the least of their issues next year.

fair enough, I was only replying in response to where the discussion was going

And I was just speaking my mind - it wasn't directed at anyone

Please expound... it what other way would a team dump excess fuel weight if there happens to be a long SC car period at the start of the race?

I am not trying to be rude but some of you really should look on the FIA site and check out the FIA Environmentally Sustainable Motor Sport Commission and check out why it was established. Fota was not set up just to stop Kers but to cut against this FIA incentive for the benefit of the greedy fossil fuel using car makers.
Throwing away fossil fuel goes completely against these FIA principles and would only help to destroy the sport.
