Ferrari Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

must be piezoelectric if they are injecting multiple times per combustion event as the rules allow

Three (interesting) posts about the history of direct injection have been moves to another thread, where they fit much better.

It is not white, it is not black, it is probably gray.

Charles Leclerc will use the same power unit in China that he used for the Bahrain Grand Prix. The unit will be duly fitted on the number 16 car, in which the Monegasque driver had to settle for third place having led the race in style until a few laps from the flag.

Anomaly. Following the race, the Scuderia Ferrari Mission Winnow technicians and engineers traced the fault on the car to a short circuit within an injection system control unit. This type of problem had never been seen before on the component in question.

That's an odd fault. First of all, why would they have another control unit dedicated to injection, the standard Mclaren Electronics ECU should be more than capable of handling that part. Maybe some small circuit boards built into the injector looms? But what would be the purpose?

That's what I was wondering. Isn't control of the power unit handled by the standard control hardware? Isn't that also a controlled and limited part? According to FIA documents, nothing unusual was spotted in scrutineering or changed in parc ferme on Leclerc's car. Lets see what they say about elements next race.

always suspicions on Ferrari as soon as have the best (write something)*.

Come on.. Why?

Yep, at least we aren’t talking about the smell of the fuel... oh wait!

Toto said is a matter of engine.
Rbr said is a matter of orange juice in the fuel
Binotto said is a matter of Cx and aero
Renault will say it s a matter of olive oil!

The reality is not known. For what we know, is not a matter of twin batteries.. and not of addictions in the lubricant.

It would be awesome if Binotto said they put a can of Red Bull on the fuel...

Always suspicions on anyone, when they have the best stuff.

Yeah, apparently the Ferrari PU runs on grapefruit juice. I wonder what that's about.

A driver board?

I remember I've already read something about the presence of mercaptans in racing gasoline, but I don't remember when and where.
I wouldn't be surprised if someone had pushed the research beyond the present limits extending the analysis to other terpens such as nootkatone or other aromas.
But I'm a little bit skeptic when I read that the flash point of that component is only 100 °C...
Anyway, it's a long time that people is complying against the smells in the boxes...

https://en.wikipedia.org/wiki/Grapefruit_mercaptan
:wink:
the Noonakatone (not linked here) seems potentially to qualify as a biofuel (remember 5.7% of an F1 fuel is bio)
so qualified it would give far greater heating value than more established biofuel qualifiers like bio-butanol
good HV/kg (and btw outstanding HV/litre)
5.7% biobutanol would have about the same heat as 4% of the non-bio fuel
the above 5.7% would give about 1.5% more ICE power

this linked above seems to be a cyclohexene type product (it might also qualify as biofuel ?)
cyclohexene has a good (v.good if bio) lower heating value LHV of 46.26 MJ/kg)
cyclopentenes I suggested a few years ago (as having a 50.5 MJ/kg LHV - and high octane number)
eg cyclopentane (pentane not pentene) is very high octane - it has a RON of 141 and a MON of 141
but FIA rules then appearing allowed (for the 94.3% non-bio fuel ingredients) far less cyclopentenes (than cyclohexenes)

the heating value of such eg grapefruity substances likely won't ever have been measured - and couldn't reliably be calculated
but octane numbers of eg fuel blends might now be predicted by ANNs using molecular parameters from NMR spectroscopy
https://pubs.acs.org./doi/abs/10.1021/a ... ode=enfuem
btw many similar fuels have a lower MON than RON so don't work well at high peak combustion temperatures

iirc 'enthalpy of combustion' divided by molecular weight = upper heating value UHV - people might check that
there was/is an apparently useful site erroneously listing many 'rare' UHV values under the heading LHVs
(so the HVs of some of my early suggestions were optimistic ie wrong)

I can't interpret this sentence. Not sure what you're trying to say.
