2009 Testing - March (Jerez & Barcelona)

[timbo]

SECU does not allow the engine power to be cut by any other way but by the reduction of throttle input. No traction control... thankfully.

That is engine power. Imagine two possibilities.
1) Your "start" engine map is laid in such way that engine is always run a bit lower that tyres can handle. Additional power from KERS put them on sweet spot. Control KERS to control wheelspin.
2) Engage KERS (as generator) when you detect wheelspin. I.e. use excessive power to charge batteries.
Both ways allow to run engine with constant throttle but achieve effect of TC.

However, if KERS is run from SECU it must be easy to limit those possibilities.

The FIA have explicitly ruled against the use of KERS as a form of traction control.

[Shaddock]

You can charge the KERS device whilst the engine is idling (~6-7000rpm) on the grid pre start.

[Conceptual]

probly not, if you can spin the wheels with the engine than why waste the limited stored KERS energy per lap by helping spin the wheels more. As soon as you can go full throttle without spinning the wheels than bang the KERS button... same with coming off the the corner onto the longest straight. With these big power cars everything is gription limited.

I dunno...

I think engaging the 80HP KERS first may give you enough of a start that you may get to WOT w/traction quicker. ESPECIALLY if the KERS unit is fed in through a CVT...

Ciro, does your brain spit out any maths concerning this?

Thanks!

Max accell comes with just a little bit of wheel spin, 80 hp is not enuff to spin those big rear slicks.

Just think about how much throttle they give it to spin them up when they are warming up in formation lap.

Sure, but my wifes car weighs more than an F1 car, and only has 95hp with radials, and that thing takes off pretty quick in first gear.

I think Kilcoo may be onto something with the low rev thing. 80hp through a CVT should be enough to start the forward movement, and maybe "just enough" to launch the car the first meter, and then the 800HP can kick in.

I think however, this is only going to be revealed during the season to see what advantages the teams have put these units to...

What is the guy with the N Tank on his back doing with the car???

Is this something KERS Related???

[Scotracer]

The Pneumatics?

[RJC_pt]

Kers cooling?

[wesley123]

Interesting

Its some sort of gas, but dunno how its called
I dunno where the N stands for in science

[SoftBatch]

N is Nitrogen although since nitrogen naturally occurs in pairs N2 would have been a better description.

[wesley123]

It could be used to refill the suspension systems.

[scarbs]

Most likely to fill the engines pneumatic system (for the valves). Although the bottle seems awfully large.

i think this is liquid nitrogen to kool the KERS system, almost sure of it. makes a lot of sense, good idea from BMW there.

No it's not. Hint - you'd have ice on the "cable". Cryogenic devices looks different.

It strikes me that being able to start a race with charged KERS
gives KERS runners a big advantage off the grid.

As others mentioned, it might not be useful until 2nd gear phase
when you're at full throttle (i.e. your not backing off the
throttle to control wheelspin)

After all, why waste the charge of your KERS for an extra 80bHP,
when you've still got spare horses available under your right foot?

The only reason I can think of where you'd want to consume KERS
power at less than full throttle is to save the engine.



Eau Rouge should be interesting with a boost button...

I feel that the FIA will eventually make a ruling disabaling KERS for the first sector of a lap (or first 30 seconds of the race, whatever is shortest) to make shure that the grid is equalised off the grid if theres going to be a big enough advantage, making starts pretty much what they used to be, but making the fun start from lap 2 onwards.

But on the otherhand, there could be a advantage for the non KERS cars for example at Oz (into turn 2) or Bahrain (into turn 4) as the KERS systems will be spent and the non -KERS cars can slipstream down the inside whilst the KERS car infront cant engage the boost as its spent and is recharging.
