Binotto-Ferrari: the official resignation and farewell of the team principal is coming soon​

by Daniele Sparisci and Giorgio Terruzzi

The team principal has decided to leave the scene due to the lack of confidence of the president Elkann. The parties are defining the terms of an agreed separation, the official announcement soon. Among the hypotheses for the replacement, the CEO Vineyard «pro tempore»

The relationship between Ferrari and Mattia Binotto ends here. According to the Corriere, it is a matter of hours for the official announcement, as the parties are reportedly finalising the clauses enshrining the terms of an announced and, apparently, agreed separation. The news has filtered out almost casually from foreign sources linked to Charles Leclerc's entourage. They do not speak at Maranello without managing to conceal an embarrassment; it is impossible to communicate with the team principal who is said to have decided to leave the scene in the face of a persistent lack of trust on the part of president John Elkann, with whom relations have been cold for a long time.

Yikes, this is a silly season on its own! :popcorn:

Ferrari Team Principal: Vasseur discarded, possible return of Ross Brawn: https://rossomotori.it/2022/11/team...tato-vasseur-possibile-ritorno-di-ross-brawn/

“[…] Vasseur remains a candidate to succeed Binotto, even if his name has aroused some perplexity in the environment (he is still the number one of a low-ranked team). An alternative hypothesis is the ad interim appointment of the managing director of Ferrari, Benedetto Vigna, and the appointment of a technical director, a figure canceled by Binotto. Just Vigna in an interview with CNBC, quoted Enzo Ferrari's motto: «The runner-up is the first of the losers» . The hypothesis of Andrea Seidl, now head of McLaren, seems to have lapsed, while the hypothesis of a return of Ross Brawn appears suggestive, technical director under Schumacher and now parked as director of F1. Whoever takes up the position will be the fifth team principal in the last nine years, which has seen Stefano Domenicali, Marco Mattiacci and Maurizio Arrivabene take turns” .

How Ferrari quietly sorted its core F1 engine reliability problem: https://www.motorsport.com/f1/news/...-core-f1-engine-reliability-problem/10405619/

"... According to sources, the weak element in the power unit had been singled out as the spark plug within the pre-chamber.

This was the latest evolution of the TJI (Turbulent Jet Ignition) combustion system that Mahle had made available to Ferrari in 2016, and which had allowed the team to close the power gap to Mercedes.

In the six years since, enormous strides were made in the development of a system that has been optimised for the latest generation of power units that were homologated to be frozen until the end of the 2025 season.

The TJI system includes the spark plug and the fuel injector. Both are housed in a well in the cylinder head, and both elements work together to help maximise power.

Only 2-3% of the fuel is injected into the pre-combustion chamber, the rest spreads over the piston surface. The mixture inside the “cap” is particularly rich, while the combustion agent in the chamber is leaner, with more air than fuel.

The ignition of the spark plug reacts with the very rich mixture in the pre-chamber, and causes the creation of plasma jets through open holes in the cap. Thanks to a very high pressure, the lean mixture is self-ignited in several points of the chamber with a flame spread that extends to the entire volume of the cylinder.

The system makes it possible to shorten combustion times, which delivers two advantages. First the very lean mixture in the chamber means the harmful effects of detonations are reduced, meaning you can increase the compression ratio for more performance. Plus, with teams still limited as to how much fuel can be used in a race (currently 110kg), for the same amount of fuel injected, greater thermal efficiency is obtained - which also equates to more power.

Ferrari pushed development to exploit the maximum pressure of the injection system, which reaches 500 bar as allowed by the regulations, and aimed for five discharges for each engine cycle. But the extreme concept led to increased internal temperature, which caused the spark plug to suffer and eventually break.

The engineers, therefore, had to tweak their mapping to not push the spark plug over the limit, while an external supplier worked on delivering new materials to ensure that the component could cope with the needs of the engine in maximum power mode.

Ferrari’s performance in Abu Dhabi suggests that the spark plug problem seems to have been solved, which will be a big boost to Ferrari’s hopes for 2023 where it knows it cannot afford a repeat of its reliability woes. "
