The 2014 F1 Turbo

[rage2]

This year, F1 is all about efficiency, and the turbocharger has an energy recovery aspect to it (aside from compressing air) with the MGU-H.

In between the compressor and the turbine sits a motor generator that is now used to control boost pressure instead of a wastegate (although a wastegate is still present in case of failure). When boost reaches max, the generator kicks in to reduce shaft speed and limit boost, while generating electricity and charging a battery. This stored power is then used by the unit to spool up the turbo when needed, thus eliminating turbo lag. Excess power is also used to power the KERS system, which provide additional power to the drivetrain.

Pretty sweet setup, no turbo lag even with a big turbo, hence much sharper throttle response. Even at elevation where we get way more turbo lag than at sea level, this will overcome low rpm lack of power. Best of all worlds.

Wonder when this will be reliable enough for road cars, I believe it's already in heavy diesel trucks (electro turbocompounding).

Unbelievable development in these engines, I will try to post up some articles with some more in depth stuff. The turbochargers are so large that they would be pretty much unusable without the electric assist

[KRyn]

Very impressive! Whats the maximum allowed boost pressure you can run?

[rage2]

There is no max boost limit in the rules, only max fuel flow limits, which in turn dictates max boost to around 37psi boost, or 3.5 bar absolute pressure.

Here's are the 2 2014 F1 engines where pics have been released so far. Completely different turbo/MGU-H packaging:

Mercedes:

Very cool stuff indeed.

That turbine housing looks like something off of a big diesel turbo lol.

[vtec4life]

will there be huge blow off noises ?!? lol

Having never followed F1 I have another question. How is this rule enforced? Real time monitoring, do they supply injectors that have to be used or limit intake size?

Not as huge as you'd think. Coming off WOT, where the turbo is at max 125,000rpm speed, it takes a bit of time for the generator to eat up that energy and slow the turbo down, so there is a BOV to relieve excess intake pressure. So you hear very minimal BOV fluttering noises as the MGU-H tries to absorb that energy as quickly as possible.

Real time monitoring.

That would be a waste of energy! :rofl:
Id assume its all recirc systems?

[Ca_Silvia13]

I love this racing technology that can be easily passed down to the real world. 2 Questions though:

1 - Who is manufacturering the Turbos? I.E. Garrett? Holset? or In house?

2 - Anyone who has any additional tech info about the motor/turbo setup please post it.

[sidewaysD]

That detailed info you have requested..


Will become avalible after the pre-season testing is complete.

Manufacters, and teams don't release too much information till they all have each teams benchmark on their performance. Yet, when kits and packages come throughout the season you will see it being a big secret and than a few races later the information will become public knowledge. (Such as the F-ducts back in the day, blown diffusers, etc)

Perhaps, after the first grandprix (Australlia) more info might be realeased.

[rage2]

1. Mercedes-AMG: In-house. Ferrari: Honeywell. Renault: Pankl-APC. Mercedes-AMG built their entire PU in-house, with the exception of the battery.

2. What info are you looking for?

edit - this can be useful for understanding where all the energy goes, and transfer limits per lap.

The most interesting piece is the unlimited transfer between MGU-H to MGU-K, which means coming off a corner, MGU-H and MGU-K takes on electrical energy to eliminate any turbo lag, and once it hits full boost, the MGU-H limits turbo speed and generates electricity which is pumped directly to the MGU-K for more power to the wheels. There's no limit to this at all.

So how much hp do these new engines produce? or is it last years engine with a top mounted turbo?

est. 600hp from the engine, 165hp from the MGU-K, total of around 765hp.

The engines share nothing in common with last year's V8's.

Currently, the Mercedes engine is rumored to have a 75hp advantage on the Ferrari engine, and 165hp advantage on the Renault engine. On the Ferrari comparison, nobody knows where the power is gained (engine or MGU-K), on the Renault side, their MGU-K is pretty much broken and unusable for long periods of time.
