Is this even allowed to changed with current restrictions on in season development?PlatinumZealot wrote: ↑11 Dec 2021, 01:55The energy to and from the energy store has gone past limit returns.

Since the rev range doesn't change, the only difference would be increase compression? If the spec is locked, and I imagine the CR is already very high, how would you achieve that?
What's the consequences of higher CR? does it change the exhaust to that drives the turbo? If the ICE is more efficient then less heat to recover from MGU-H right? Less MGU-H then less flow between ES and MGU-H?
That's the part I am not understanding.
The heat input into the MGUH is unlimited however.
If your ICE can operate in away to make the same power while pumping more air, you will have way more energy to the MGUH. Alternatively if you can squeeze more energy from the fuel into the air you can extract more mechanical power to the pitsons and loose less to the cylinder walls.
This is very achieveable if detonation, and also lean flame stability can be controls because you see these engines are still detonation limited and are on the limit of running lean. New fuel formumations, new injections strategies, new piston and liner materials and shapes.. Lower friction parts.. Etc. All of these give more ICE power and /or you can run the engine harder for longer. It's like a domino effect.
If it can be seen as a reliability update it can. For example the latest merc ice was supposedly several hundred grams heavier. Thus it's safe to assume something got beefed up.One and Only wrote: ↑14 Dec 2021, 14:49Is this even allowed to changed with current restrictions on in season development?PlatinumZealot wrote: ↑11 Dec 2021, 01:55The energy to and from the energy store has gone past limit returns.

Hamilton took his fifth internal combustion engine of the season at Interlagos. As is well known, Mercedes have been carrying a reliability issue with its power units during the second half of the season, believed to centre around a materials batch issue, with cracks developing around components in the bottom end of the engine.
What's the point of keeping on the 2nd MGU-K with a lot of mileage instead of using a "free" 3rd ?_cerber1 wrote: ↑17 Dec 2021, 08:56It should be noted the incredible reliability of the hybrid component of the Mercedes engines. Hamilton finished the season with 3 MGU-H and MGU-K, Ricciardo and Stroll with 2 MGU-K.

The engines are frozen starting next year, so to make the engine more powerful a change has to be disguised as a reliability upgrade! Additionally most of the staff RB acquired where on the manufacturing side, not the design/engineering side, and are on gardening leave.
Probably the new K has to be fitted at the factory, as it is a precision job. the ICE TC K & H are shipped together as one assembly. So the built the 3rd and 4th assembly recycling the old K of the 1st and 2nd ICE.Spoutnik wrote: ↑17 Dec 2021, 10:38What's the point of keeping on the 2nd MGU-K with a lot of mileage instead of using a "free" 3rd ?_cerber1 wrote: ↑17 Dec 2021, 08:56It should be noted the incredible reliability of the hybrid component of the Mercedes engines.

If you want more energy, most straightforward is to increase the hot airflow in exhaust and turbocharger. More airflow, means more energy for the MGU-H to recover. More energy to charge the ES, more energy to deploy with the MGU-K.rogazilla wrote: ↑08 Dec 2021, 16:45That part I get. It is the 'drive harder' part that makes no sense to me.
