Ferrari Power Unit Hardware & Software

[siskue2005]

FERRARI is now in a position, made possible by acquired improved reliability, better fuel consumption and better harvesting to be able to operate in free load mode on every lap on all straights for lap after lap of the race and not only in qualifying and by strict permission from pit wall during the race.

That is not possible according to the current rules and restrictions

Can you clarify by bringing up the appropiate regulations? Not saying you are wrong, but this is technical thread where it is expected to be a bit more than just "that's not possible".

I would also like to know the technical detiaps of how Ferrari can operate in free load mode for every single lap of the race and on every straights.

What goes from ERS-K to crankshaft is limited as per the rules no matter were it is coming from, also measured as well as recorded in data logger of which FIA have access at all time. any attempt at bypassing what goes from ERS-K to crankshaft meassurment will be on the wrong side of the rules.

Yeah.. what are you trying to say?

The K only allows 2MJ to be transferred to ES....it will be difficult to even harvest 1 MJ per lap on average circuit....then how can free load mod aka 4 MJ full power harvesting can be done every single lap of a race and also deploying them completely every single lap of a race on every straights?

[Tommy Cookers]

if the cars ability to use K motoring is undermined by insufficient traction below 150 kph or 200 kph or whatever ....
(and H***a seemed to do brake-off K generation at any time below this speed)
and K motoring near the end of a long straight is an almost worthless use of limited ES energy ....

what is the actual target for K motoring seconds per lap ?
ie does (or not) so-called WOT time correctly denote K motoring target time ?

and matters in JasonF1's post may imply that the H might not need to drive the compressor for as long as we thought

that any attempt at bypassing what the rules allows from ERS-K to crankshaft of which is measured will bhe on the wrong side of the rules.

Yes I agree that on most tracks it is not easy to harvest the 2MJ that the rules allows by ERS-K. One of the present improvement made is the ability to harvest from both knitic and heat to recharge the ES to fully charged state while on the same lap free load mode have been deployed during the lap, recharging the ES to fully charged state will make free load mode avialable on the next lap (in free load mode both ERS-H and K are sharing ES power.

it won't be on the wrong side of the rules because .....
there is no rule preventing K motor action exceeding 4 MJ per lap .....
if the MJ over 4 doesn't come from ES energy and the K motor action doesn't exceed the nominal 120 kW power

How can 2MJ from KERS recharged every lap and also deploy the 2MJ on that lap....

In any normal circuit it is difficult to even get 1 MJ from the braking and harvesting.

And if I am not mistaken in free load mode u cannot deploy the harvested energy ...hence the name

Ok it seems u have edited .

Nevertheless 2MJ from K and rest from H... still I don't get how they can recharge ES to 4MJ in a normal circuit as there is a limit for braking force and the amount of energy transferred to ES .... and I am sorry but I don't see how free load mode of fully charging the ES with 2MJ from K (which is impossible unless u brake in more places) is possible in every single lap of the race. The restriction in harvesting energy will not allow it

It's called engineering for a reason. They push and invent new solutions. I dont understand how you can be sure about a thing being impossible to do, especially for a relatively new technology the hybrid system is.

[turbof1]

Surely somebody with the necessary academic/professional background can come along and clear that up?

As this is technical forum....please give technical details of how free load mode and full delpoyment of energy can be done on every single lap of the race?
That is what I said is not possible due to the restriction in harvesting energy in K and nearly major tracks were only up to 1 MJ can be harvested in a lap (this is due to the track characteristics and other factors of braking duration and time of harvesting.....there is a physical limit....we cannot bend the rules of physics with better technology )....so free loading and full delpoyment won't work in every single lap of the race

Clear up which part? The Ferrari PU thread is the new Honda PU thread.

[RZS10]

Leclerc said that Haas and Sauber are getting fresh spec 2 PUs - the same Ferrari is using - but with new engine mapping which Ferrari uses since Austria.

This essentially confirms that the "straight line performance boost" does come from the engine side and not aero (as some have speculated) ...

It would probably help to define what free load mode actually is. To me it’s a made up term in this context.
