Biobutanol is very close to gasoline. It's quite expensive and energy intensive to make. Nuclear power plants can make it as a byproduct with raw materials.PlatinumZealot wrote: β21 Feb 2022, 17:12I'm almost 100% that biologically derived fuel for use in petrol engines will be alcohol.
the only other thing I've heard of is some algae synthetic petrol. But I don't think that is what is being used yet. That's still in the testing phase when last we heard from Ross Brawn.
Ok it is an alcohol though. The name gives it away.godlameroso wrote: β22 Feb 2022, 22:06Biobutanol is very close to gasoline. It's quite expensive and energy intensive to make.

https://www.formula1.com/en/latest/arti ... J8okc.html2022 will already see Formula 1 move to E10 fuel, a mixture of 90% fossil fuel and 10% ethanol.
Until the Abu Dhabi 2021 race, the Formula 1 cars used an E5 blend, with 5% ethanol and 95% fossil fuels.

Ethanol LHV = 29.7 MJ/Kg
Gasoline LHV = 46.4 MJ/Kg
Let the relative LHV of gasoline be 1 and butanol be 34.4/46.4 = 0.74
Let the relative LHV of gasoline be 1 and ethanol be 29.7/46.4 = 0.64
2021 E5 fuel (butanol) relative LHV = 95% x 1 + 5% x 0.74 = 98.7%
2022 E10 fuel (ethanol) relative LHV = 90% x 1 + 10% x 0.64 = 96.4%
Relative expected drop in power compared to last year assuming non detonation limited =
(96.4% - 98.7%)/98.7% = -2.33%
So all esle being the same the new E10 fuel should be 2.33% weaker than last year's E5 fuel.
Since the ICE are about 850 hp this loss is about 19.9 horsepower. All esle being the same.
And new fuel flow regs, injectors, etc. That would be a lot of extra weight in fuel unless they want the cars to slow substantially.PlatinumZealot wrote: β26 Feb 2022, 03:33Should. But the fuel mileage will go to the dogs. They will need bigger fuel tanks.
I think all engines had a split turbo design.
Wouldn't be surprising if Ferrari is at or near the top this year. I think they were pretty close to Honda at the end of last season and they made it clear the 2021 engine was just an interim improvement vs the all-new 2022 PU.LM10 wrote: β01 Mar 2022, 18:37#AMuS reports that from their sources at Ferrari, the new PU is a bigger step than what we have seen in 2020/2021. They completely focused on getting more power (since the technology got frozen on 28.02.)
Ferrari will bring an improved version of the hybrid system in the summer.
Helmut Marko told RTL that he believes it is going to be a fight between Mercedes, Red Bull & Ferrari. Red Bull is overall satisfied with the first test week. He also said that it seems that Ferrari is the leading force in terms of engine (though we donβt know engine mapping yet)
