I think Honda would be better off with their own team. (Edit - Obviously Red Bull - Honda would be best of all! Red Bull Racing are a slick operation and I'm not sure Honda could do better on chassis matters, at least not in the short to medium term.)
That Honda used carbon-neutral fuel for the 2021 season, according to Yasuaki Asaki, now head of HRC Sakura's four-wheel race development department.
F1 has also decided to use 100% carbon-neutral fuel from 2026. Other categories have already introduced this fuel or are preparing to do so.
In such a situation, Honda introduced the product ahead of its competitors as of 2021. It has demonstrated the same performance as conventional fuels. Moreover, the material used for the carbon neutral fuel was prepared by Honda, not by ExxonMobil, a fuel manufacturer with which Honda had a partnership at the time.
What exactly was being done? We interviewed Dr. Kotaro Hashimoto of the Advanced Power Unit and Energy Research Laboratory at Honda R&D, who was involved in the development of carbon-neutral fuel at the time.
「During the 2021 season, Honda developed a high-performance component in the fuel that is carbon neutral!」
Dr. Hashimoto states.
「What we did was to make 58.5% of the high-performance component in the gasoline a renewable component.」
「The e-methanol was made from hydrogen created using renewable electricity and carbon from the inedible parts of plants, in this case woody biomass. We synthesized that e-methanol with second-generation bio-chemicals and even chemicals to create the high-performance components of F1 fuel!」
「Theoretically, it is possible to make the product without chemicals and with 100% renewable ingredients.However, Honda was only supposed to do F1 until 2021, so due to time constraints, we decided to use chemicals this time. As a result, 58.5% were carbon neutral. We gave it to ExxonMobil and they blended it into gasoline for F1!」
「Although the raw materials are different, the resulting product has exactly the same ingredients as those derived from fossil fuels.」
What Honda created this time is a "high-performance component" of gasoline, which is used to increase the output of F1 engines. Fuel used in F1 is basically regulated to have to be the same ingredients used in commercial gasoline, and the available ingredients are very limited. Dr. Hashimoto says that from among these, he selected the most suitable material for today's F1 engines and created the ingredients for them.
「The current regulations specify the fuel flow rate. In order to increase output, we have to increase the calorific value of the fuel. On top of that, the thermal efficiency must also be high, otherwise the output will not increase.」
「In order to increase efficiency, the compression ratio must be increased and the ignition must be done at the ideal point. However, as pressure builds up, abnormal combustion (knocking) will occur, so we must make sure that does not happen either!」
Dr. Hashimoto explains the development of high-performance components for F1 fuel.
「Therefore, we searched for hydrocarbons with high calorific value that would not cause abnormal combustion in F1 engines. We derived this by calculation. For that calculation, for example, just looking at a single isooctane (saturated hydrocarbon/octane isomer) yields about 1,000 chemical reaction formulas.」
「What ignites the fuel is an oxidation reaction, but if we look at it in detail, many reactions are taking place. By looking at these reactions one by one, we can see under what conditions ignition occurs. By solving it, we can determine which ingredients are good for the fuel.」
In this case, a portion of this high-performance component was made carbon neutral, but Dr. Hashimoto says it is quite possible to replace the entire portion of gasoline with carbon neutral.
It can be done 100%. Technically, there is no problem at all. But you have to make a lot of them, and that cannot be done by Honda. But there must be some way to make it.」
Honda's carbon-neutral fuel, which was first introduced in F1 in 2021, is not just for the purpose of achieving carbon neutrality in motorsports.; it is a step, and a big step, toward changing the future of motorization from F1.

The only thing that makes them “green” is that trees grow faster than coal and oil reserves form, they’re not any better from an environmental standpoint.

I believe that is the blow off for overpressure in the intake. They used to blow off into the inlet for the compressor but now they blow off into the exhaust.etusch wrote: ↑27 Dec 2022, 13:00Thank you @likIik wrote: ↑25 Dec 2022, 10:31

I wonder what is the pipe comming from exhaust towards intake. Is there anyone to guess or know it ?

Not available from 2022.
That is the PU run during 2021.
I thought it was strange too, but a friend of mine who speaks Japanese explained it:
