So this is just a ride along nanny sensor that has no purpose but to report back info to FIA? And would RB's math have shown more fuel flow or less?

 

That's the point, Red Bull contends the sensor was inaccurate and sending the wrong info, which the FIA relied on when they told them to use it or else.

So, if Red Bull can prove the sensor was wrong and the fuel used was never out of reg, will they win? I don't think so, but one can hope.

The open letter was interesting and I agree with the sentiments expressed there - I don't understand either why they have to regulate the rate of fuel flow, I'd think regulating the how much they have to use would be enough.

But that does leave open an end around if a fuel supplier for a particular team can make their fuel have more BTUs of energy for the same volume (or weight, however they measure it)

It's a complex matter for sure.....

 

I had a quote a few pages back that kind of addresses that. It's kind of obtuse, but here it is: (from the free issue of RaceCar Engineering)

 

The FIA sensor is to measure peak flow as the rule says not average flow. I can't find in the regs where it says it must be by the FIA sensor. If RB can prove their sensor and readings meet the standard and rule they may win.

 

It was posted a few pages back.

Apparently the sensor is more than a monitoring nanny, and also restricts the flow proportionately down through the RPM range from this:

It also appears that there are other folks that see the benefits of running rich when dealing with a hot engine....

Everything I've read has said that it's designed only to run an ultrasonic pulse between two transducers, and measure the timing of the pulses. No moving parts are involved specifically to not restrict the fuel.

The rules are written so that there is a restricted fuel flow at lower revs than 10,000, but it's not the sensor that's doing that. If an engine is using 100kg/h at revs lower than 10,000, then they are in violation of the rules.

So if the engine is at 9000 rpm, they can use up to 99kg/h of fuel, but no more until they reach 10,000~10,500. AND, they can't use more than 100kg/h at 10,500.

BTW, I absolutely LOVE that we are still talking about the race, even if it is just going over minutia.

 

Locked wheels under braking isn't caused by the new engines lack of sound. Locked wheels have always squealed. Or are you saying that harvesting is causing rear wheel lock, in which case yep it's the new power lump.

 

I have heard locked tires making that sound before these lumps. Yep it was a might harder to hear, but the sound was there.

 

What Nathan said. The engines used to drown out the wheel lock / tire squeal / everything else.

 

Isn't that the same as picking yourself up by your bootstraps?

If at max power (50% of the time at Monza, isn't it?) you are taking energy out of the battery to drive the turbocharger, when and from what is that amount of energy going back into the battery? Do these cars even have a regular engine-driven alternator any more?

 

The MGU-H can operate either as a generator or as a motor, not both at the same time. So if you're spinning up the turbo to increase the boost past what the exhaust gasses are producing (beyond what's needed to reduce turbo-lag), you're losing battery energy and burning precious fuel. You could do it, but it seems like a risky strategy to me.

I'm not sure on the alternator. They had them last year (Renault kept having problems with them). I'll see what I can find out.

 

The batteries recharge when not at full boost. Most of the tracks they're not at full throttle anyway. The over boost may not be used all the time just when needed. Just an idea.
