2021 Engine thread

[AJI]

So what are the most likely outcome of the new 2021 regulations?

Keeping the 90° V6 single turbo platform (maybe even allow hot-vee configurations, which I find unlikely though)
Removing MGU-H
Larger MGU-K possibly around 200kw
Fuel flow regulations raised to 120kg/h
Peak fuel flow limit raised from 10.500 rpm to 13.000 rpm
Theoretical rev limit raised from 15.000 rpm to 18.000 rpm
ES Capacity raised from 4MJ to 5MJ

Thoughts?

I think that's pretty close to what the spec will be. Safe and boring with huge expense in optimising existing tech to the nth-degree, rather than huge expense in innovation of new tech.

If they want to extend the engine revs to 18000, they should increase peak fuel to 16000-18000 too.

And with a future of full electric vehicles, development of combustion will slow down anyway.

non the less lately i was reading an article about
Lockheed Martin Now Has a Patent For Its Potentially World Changing Fusion Reactor

Lockheed Martin has quietly obtained a patent associated with its design for a potentially revolutionary compact fusion reactor, or CFR. If this project has been progressing on schedule, the company could debut a prototype system that size of shipping container, but capable of powering a Nimitz-class aircraft carrier or 80,000 homes, sometime in the next year or so.

So we are going to be racing nuclear powered doing containers then? I'm not sure if I'm excited or repulsed!

Should fit right into the back of the looooooong Mercedes.

HAHA
2014 witnessed ICE new direction in F1...

Lol, they sure have the wheelbase for it!

I would think the maximum rpm will remain at 15k, but the operating range will be raised from 10-12k to 13-15k.

Is there any talk on PU numbers per season? I'd assume that raising the RPM will decrease lifespan?

Until they can be placed above the Q=0.1 line on this sort of plot then their claims of a working, electricity producing reactor should be taken with a truckload of salt.



This MIT video is good introduction and summary to the state of fusion power today:

Would like if they reduced the number of gears back to 7 or even 6, forcing them use a wider rev range than just 2000 rpm, and it would also be more challenging for the drivers, as a bad shift would mean you get out of the optimal rev range. Not like now where they are always in the optimal rev range, and getting the shifts right doesn't really matter

I agree with you. I like the idea of 6 gears...

[mclaren111]

Totally agree. 6 gears

[Singabule]

Totally agree. 6 gears

But allow final gear ratio to be changed every GP

[mclaren111]

Yes.

Or perhaps allow a low, medium and high speed box. 2 of each for a year ??
