2021 Engine thread

The plug-n-play aspect really decreases the benefits the works teams currently have. I don't like mandating being able to hot swap PUs. I'm sure TR and Mclaren would argue otherwise.

I don't expect the PUs to be much louder with 3000rpms more yet still corked by a turbine.

So now the ES is standard, the controls are standard, the way the block is to be built is damn near standard, the turbine has tighter limits, and the fuel will be tighter regulated. Depending on how tight the fuel is regulated could standardize combustion design. We might as well just have one PU supplier at this point.

F1 is once again an aero formula. Red Bull is probably ecstatic.

will there be any use now from putting compressor on one side and TC on other? Without MGU-H there will be very long shaft that is connecting C and TC and losses with longer shaft are there, vibrations?

If it's allowed (there are some idea's in the new rules about size and weight), there are still the same advantages: Better heat management, not restricted with the diameter of the compressor (because of the driveshaft) and the length of the intake. I don't think the electro motor/generator works as a big help to stop vibrations/torsions. I think it would be even easier, with less weight and forces on the shaft. Just some extra bearings

Doesn't look like there is a large scale acceptance for this PROPOSAL.

WOLFF: THIS IS THEIR VISION AND WE HAVEN’T ACCEPTED IT

Formula 1 world champions and engine suppliers Mercedes have cast doubt on the new engine regulations proposed for the pinnacle of the sport in 2021.

Mercedes F1 boss Toto Wolff says he has “strong scepticism” about whether the ideas are the right way forward.

An outline of potential rules has been published by governing body the FIA and commercial rights holder the F1 Group.

“This is their vision and proposal and we haven’t accepted it. The flaw of the concept is that it’s a completely new engine and new investment,” said Wolff.

But Wolff said he was “surprised” that the FIA had published so much detail on the new engine when the manufacturers had been told in a meeting on the same day that the plans were “a proposal of a vision for 2021” that would be subject to further discussion and refinement at F1’s various rule-making entities.

That's not surprising. Renault and Mercedes have been against the 'dumbed down' turbo units. I'm not sure where Ferrari stands.

[ripper]

Rumors from Italy say that Ferrari is aligned with Mercedes and Renault.

Allowing Electric Turbo's would have been really neat and Road relavent.

adds weight to the turbo just to get around lag and if your more thinking of a electric supercharger they are less efficient than an energy store to a motor on the wheels.

braking force to store then use on motor
braking force to store then spin up a turbo or supercharger to then compress air is not worth it

[Jolle]

To me it feels like this new directive should have been the PU spec instead of the very limited V8 2.4's before the current PU.

[draw73]

I really like the current engines. I’ve never been to a race so don’t have an opinion on the noise levels. I feel if they were to limit the amount of energy that could be sent from the MGU-H to the MGU-K it might level the field a little bit. I think that this maybe Mercedes edge allowing them to run the MGU-K longer than any other team.

I can't agree completely with that. A 1.6Litre N/A won't be competitive in Formula 1.
I think you vastly underestimate the power benefit possible by turbocharging. You can't even reach the 100kg/h fuel burn rate without super-charging a 1.6l engine.

However i agree with you that a "electric" turbo charger has a lower efficiency than the normal turbo chargers we have seen and build for years, which proved to be quite nice

so, nothing about 4-wheel drive?

I was kid of hoping to see 4-wheel drive F1 cars

I think i remember some people claiming that the current engine formula is near the maximum of what they can harvest from the rear wheels. A electric generator/engine at the front would make sense if that was true.
(Cars got heavier -> more kinetic energy to recover?)

However it would increase the weight of the cars. IMO they should lose some weight. A lot of weight to be honest. MGUH disappearing is a good start tough

Edit: i'm curious to see what solutions the teams would come up with when it comes to integrating the generators in the front wheel hubs. The rear wheels are connected to a single generator via the driveshaft. It will be a lot more difficult at the front axle

I wonder if Merc would continue developing the split-turbo sans MGU-H. Too massive?

It sounds like FIA intend to impose weight and size limits on turbos, most likely with the purpose of getting rid of expensive to develop split arrangements. Very dissapointing.

[Just_a_fan]

Both Mercedes and Renault unhappy about the new engine proposal.

Issue is that it will be a whole new development cost.
