Perhaps we should all agree to use the correct engineering terms? This might avoid some confusion.dans79 wrote: ↑19 Jul 2018, 21:12An amount and a flow rate are two completely different things.

You might see marginal gains (or possibly losses) by just changing the fuel spec and not altering the tune and/or combustion side. In order to see any real gains you would need to tune the ICE around the fuel specification.apexcontrol wrote: ↑20 Jul 2018, 00:14yes we should give him a chance because he write's allot of stuff and is clearly thinking about it.
@gruntguru very nice and clear basics to learn the flow and generation of the powerunit.
@saviour stivala, don't worry you will get it. it's crazy stuff easily get lost in it, well i do !!
So about that damn powerunit. i do not think ferrari has the edge on mercedes, well i think shell got the edge on them all.
i think the pu of ferrari was not the best but shell did some heavy thinking and some crazy analytics. and now ferrari has the most optimized PU under this set of F1 rules.
you can tune the burner (PU) or tune the fuel inside of it, mixing fuel is easier adjustable then adjust the whole pu,
is it possible to see anywhere if ferrari adjusted the combustion side fuel wise. ?
I have a different reading of the sensor position.Mr.G wrote: ↑19 Jul 2018, 20:49Besides all the ongoing discussion, I've been thninking where the ERS can be improved for more power/efficiency...

An issue I can see with this methodology is that the energy doesn’t flow instantaneously. There will be delays in the control units, DC-DC converters, cabling etc. I have in the past mused that this might be an area where a savvy team might manage SOC or MGU-K energy flows or both to gain an advantage.
I think it is important that we understand that Flow, in electrical terms, is power.gruntguru wrote: ↑19 Jul 2018, 23:48Perhaps we should all agree to use the correct engineering terms?

"Energy" is useful stuff you can have sitting around in a bucket or a battery or a flywheel etc. There are many units used to quantify energy. The SI unit is the Joule and the F1 rules use MJ, (MegaJoule = 1,000,000 Joules).
"Power" is the rate at which energy is moved from A to B or converted from one form to another. For example an ICE takes chemical energy in the form of unburned fuel and atmospheric oxygen and converts it to heat energy. Some of this heat energy (up to 50%) is converted to mechanical energy by expanding the hot air against a piston. The unit of Power used in the F1 rules is the KiloWatt (KW) and is equal to an energy flow of 1 KJ/s (1,000 Joules per Second)
- the maximum POWER that can go between the MGU-K and everything else is limited. (to 120 KW)
- the maximum ENERGY that can go from the MGU-K to the ES is limited. (to 2MJ per lap)
- the maximum ENERGY that can go from the ES to the MGU-K is limited. (to 4MJ per lap)
- the maximum ENERGY that can go from the MGU-H to the MGU-K is unlimited.
- the maximum ENERGY that can go from the MGU-K to the MGU-H is unlimited.
- the maximum POWER that can go between the MGU-H and ES is unlimited.
- the maximum ENERGY that can go between the MGU-H and ES is unlimited.
The "amount" of energy from K to crank is unlimited, the "flow rate" of that energy is limited.saviour stivala wrote: ↑19 Jul 2018, 20:14Exactly as you said, but you left out that from "K" to crankshaft it is limitted.Chene_Mostert wrote: ↑19 Jul 2018, 19:32No its limited between ES & K, unlimited between ES & H; H & K.saviour stivala wrote: ↑19 Jul 2018, 19:13
Yes the diagram says unlimitted up to "K" but limitted from "K" OUT or IN.
It's simple really just read it as it is, witout putting your spin on it.
Appreciates the fair and just moderating.
Sorry to have kept you waiting for about 10 hours, not everybody on here is in the same time zone. Gruntguru’s post was excellent with a lot to learn from and certainly much appreciated at least by those (like me) of not being at the high-end level of technical knowledge when it comes to proper technical terms. I am also sure that people at his level when it comes to proper technical terms when in dialogue with others of lesser technical level about a technical matter have an automatic (mature) compensate for other’s shortcomings re-proper technical terms. Anyhow his great explanation finally goes a long way to show that whatever the proper technical term/s might be for the MGU-K OUT TO CRANKASHAT and OUT TO ERS COMPONENTS are actually LIMITTED.
Is this legal in F1?Big Mangalhit wrote: ↑20 Jul 2018, 09:45Found this article interesting https://www.caradvice.com.au/668862/fer ... ric-turbo/
Basically Ferrari patented an F1 engine without a crank between the compressor and the Turbine, using only electric to do the transfer of energy. I think this shows the potencial that exists into storing turbine extra energy and releasing it only when needed for maximum efficiency instead of having to waste the extra energy when exhaust flow is too high.
Also F1 relevant to road cars? I would say so
Thoughts?

This is great innovation if it's legal, and might be reason for double wiring from battery. By decoupling compressor from turbine turbine efficiency ratio can be greatly increased by letting turbine to spin at best efficiency rpm range all the time. This is a great innovation.
