2014-2020 Formula One 1.6l V6 turbo engine formula

[Tommy Cookers]

Remember that you are disqualified if you use 1g above 100 kg between lights out and the checkered flag.

EDITED
Gill, the fuel meter makers, accuracy statement suggests that will have to be at least 250 gm, not 1 gm
that is a car would be disqualified if its meter read 100.251 kg or more (this means it must have used 100.001 kg or more)
but another car that read ok at 100.250 kg might actually have used 100.500 kg of fuel

the same as the Olympic 100 m lanes varying by 0.25 m
but that would be transparent

the metering at each of the injectors will be less accurate

Remember that you are disqualified if you use 1g above 100 kg between lights out and the checkered flag.

the fuel meter makers claims suggest that will have to be at least 30 gm, not 1 gm

the same as the Olympic 100 m lanes varying by 0.3 m

(further, the fuel meter measures velocity, not massflow)

Ok, that was figuratively speaking. I reckon that there will be a technical directive how they will handle the accuracy and I do not know if they will allow for a tolerance or not. For the time I'm guessing that any accuracy fault is not an excuse to exceed the limit. You simply have to stay under it IMO. But we cannot exclude a solution where they will allow a tolerance. I'm only saying it would surprise me. The regulation is very specific about the 100 kg.

Regarding the velocity measuring principle you are right. But the rest of your statement is wrong. The sensor is an integrated unit which evaluates the physical conditions (pressure and temperature) and computes the mass flow of the fuel. That is also clear from the documentation of the manufacturer. So the whole unit is measuring fuel flow indeed.

Regarding not making it to the finish line I rather suspect that we could have five cars with reliability problems that will not make the finish line than five cars running out of fuel. 2006 we had lots of engine problems in the first few races. It is not unusual for a new engine and must be taken for granted with such a highly complex power train as we will have.

If you are not efficient enough others will be. They will win, you will loose. That is motor racing.

You're kidding right?
What you're describing is a Mobilgas Economy Run...Of course that is what F1 is turning into.
God help us if people are taught that is racing.

The reality will be upon you ten races from now. Time to face it.

And in reality F1 has been an efficiency race for the last five years. Engines are homologated and the team with the most efficient aero package has the most downforce. It wins. Or the team which makes most efficient use of crap tyres wins. So why not make the team that has the most power win for one year? Then the engines slowly will be strangled again and we can have another aero efficiency race or another crap tyre race.

From the Technical Regulations.

"1.1 Formula One Car :
An automobile designed solely for speed races on circuits or closed courses."

This needs a redefinition

Can you elaborate a bit here?

Just a poor attempt to be funny

Is should say something more like "An automobile designed for safety, efficiency and speed racing on circuits or closed courses" Its not designed solely for speed. Speed comes third

Found another interview from Taffin with interesting numbers back from March this year.

Maximum turbo boost is around 3.0 bar, or three times regular atmospheric pressure (43.5 psi in the old money). Unlike the current V8s that do their best work around 18,000rpm, Renault's 2014 F1 engine will peak at around 10,500rpm, with gear changes occurring at 12,000rpm.

Though exact power numbers are being kept secret for now, Taffin reckons it will have similar output to the current F1 engine of around 550kW (750hp) - not bad for a 1.6-litre engine.

Three things are interesting:

• turbo pressure will be higher than required for boosting at 10.500. That could indicate that there will be considerable back pressure loading.
• The rev band will normally be ending at 12.000 rpm
• Renault are shooting for equal power from the power unit as the V8, 750 bhp. If this is without recovered kinetic power it would even exceed my current estimate.

I also like the comparison with the Renault Clio 1.6 L turbo petrol engine. The F1 engine has 3.75 times the power of the road car engine. It is testimony that the F1 optimization is worlds away from the engineering of road cars. They will use similar technology but they will add the requirement to go very fast, which you don't have in road cars.

I don't think it will be any more of an economy run.

For most races the 100kg will be more than enough.

Quite sure that is including ERS.

I have done some calculations based on the fuel consumption data provided by Renault for 2012 (source)



Some take-aways that were new to me
- 2014 cars will have 40 to 50kg less fuel onboard compared to 2012.
- Consumption will be down by roughly 33% compared to 2012.

I thought I'd share that with you, as it might be interesting.

[WhiteBlue]

Excellent! Can you give us some other average data please, since you already have the data in a spreadsheet.

• average lap in km
• average % on full throttle
• average speed or lap time

That information would be nice to have for ES calculation.

[Holm86]

Great post Tim! +1

Yes, that's what I'm thinking too. I was estimating around 600hp for the ICE and then the 161hp from the MGUK. The % split from the ES and MGUH is still a little bit in the air. I don't expect teams to be able to recover 2MJ in one lap, so the ES to MGUK curve will be dependant on storage.

A couple of thoughts on the weight changes for 2014:

- the minimum weight has been increased to 690kg, up from 642kg this year
- fuel load will be down by roughly 50 kg (see my post above)

That leaves us with at least ~100kg for ERS and the turbo and the additional cooling. Worse still, this allowance doesn't take into account that the engines will be lighter due to fewer cylinders or the lack of KERS unit in 2014. Having said that, even a 100 kg allowance for the turbo, ERS and addtional cooling does seem rather excssive if you consider that the whole V8 engines this year weigh slightly less than that (95kg) - realistically this allowance is probably more than 130kg even (and that is a somewhat conservative guess). Have they increased the weight limit a bit too much?
