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.

''The FERRARI named 'superfast combustion process'. The combustion process converged upon by all four power unit manufacturers that is actually being used - 'direct injection spark-ignition turbocharged with a passive chamber'. with compressor boost as high as 5.5 bar, with a spark-plug that contains a perforated cap in itself and with an injector aimed-up at said perforated spark-plug cap. The benefits of a fast combustion is less possibility of knocking. This type of fast combustion produces/extracts the most heat from combustion/ extracts the most power, with the resultant exhaust gases carrying more heat away from it being lost to cooling which is more beneficial to turbine power capability.

Yes. The Ferrari "Superfast Combustion Process" is essentially a member of the TJI combustion family.

it is entirely valid to use the term TJI when referring to F1 engines.

The unit on the stand at the right. Starting at the front, MGU-H - Compressor intake - Compressor - Turbine. It is not a 'split-turbo'.

is there any truth to this https://scuderiafans.com/f1-2023-italia ... rformance/ ??
Before the cars hit the track, there was a communication from the Federation that both Ferraris were equipped with the fourth PU. This is the last one available for this season before incurring penalties. Obviously, this choice is linked to the high stress these units undergo during this weekend at the Temple of Speed. Furthermore, according to reports from Formu1a.uno, this fourth PU is even said to be an evolution of those used so far.

In fact, according to this insider information, the new power unit includes a development token spent on the electrical component. The area of development involved is the ERS, which has undergone careful optimization to improve efficiency. This development is believed to have allowed the Ferrari PU to gain approximately 5 horsepower, which at a circuit like Monza translates to a tenth of an advantage on the stopwatch.

5 HP = 1 tenth seems too much to me.

I didn't know that there is possibility for developing of the PU and tokens.
Where is this in the rules?

Monza is special in terms of full throttle percentage.

I don't know if there are still tokens, but only the ICE cannot be developed (except for reliability reasons); the electrical part of the PU (MGU-K/H ERS and relative SW) can be evolved during the season.

Not really. It’s also the fastest. 5hp is negligible at their average speeds. Figure they’re consuming 750hp or so just to push the car through the air. 5hp is a tenth of a mph or so in trap speeds, if even.

Also, Honda has documented shaving 12kw off peak for more mid range and, and gone faster at Monza.

Regardless, I enjoyed the retro liveries on the cars this weekend.

5hp at the top end isn't the relevant figure. It's the bottom end that matters because you carry it all the way down the straight from beginning to end.

Also "Honda gone faster at monza", by what metric is this quantified?

The 2022 power unit is brand new.

A car is both it's PU and it's chassis. The Honda is very good if not the best, but the differences were marginal today. Ferrari had fresh power units with aggressive mappings. Those engines are probably practice power units after today...
