Ferrari + Smoke Bomb: Any idea what's going on?

Couldn't help but notice the smoke pouring out of the adjacent garage every time the Ferrari started. I though my Scud was bad but this is ridiculous.

Any idea what they are doing?

 

Don’t worry, it’s where elton is sat, and every time he doesn’t get his way, the steam coming out his ears is horrendous

 

They're just taking the P:censored:ss out of the FIA's rule about venting oil fumes to atmosphere!

 

all the Ferrari engined cars were doing this at Catalunya testing......

Apparently it’s a problem for Mercedes...... makes them too quick and slippery in Bahrain.... who’d have thought that?

Don’t worry, the FIA will get tears down the phone from Toto and will ban it ready for the next race, wouldn’t want anyone but Mercedes to be allowed to win now, would we

 

I think its the New oil burn system... apparently they use the oil - with some special additives that aid in combustion from under the piston.... this pools up and you get lots of smoke - I guess this helps with detonation with the turbo? technically its for cooling, but seems that they are in a loop hole area.

 

It's already been investigated by the FIA/Charlie Whiting and it's been declared perfectly legal, so there's nothing to ban.

Charlie said that the car doesn't smoke on track, so as far as he/the FIA are concerned, it's a complete non-issue.

 

They’ll find something else, they always do. In the meantime, let’s make em cry boo hoo Mercedes.

Olio in the turbochargio is a good guess.

 

So much for low emissions/hybrid technology in F1.

 

It's an oft-hand tribute to Phillip Morris. "And now a word from our sponsor . . "

 

Turbine jet engine?

 

They did not do it for emissions, they did it for mileage--we now have engines using 66% of the fuel the old engines used, and producing slightly more power.

 

I have a feeling that the smoke cloud has something to do with the turbo failures of the past couple of seasons. I suspect that Ferrari has come up with a way of keeping the turbo bearings flooded with oil when the turbo is hot and the engine off. The end result is oil leaking past the bearing seals and burning away on start up. to bad they cannot switch on the Smoke mode when Hammy or Bottles is close behind.

 

Also they could be injecting oil into the top end on start up to get a few extra KM's of longevity out of the engine.

 

Very unlikely since they run a good chance of fouling a spark plug on startup, also it would not increase engine life. Most F1 engines are running a single low friction compression ring with coated slipper skirts and an aggressive oil ring that scrapes most of the oil of the cylinder wall. A key thing to remember is excessive oil creates extra friction this is why the oil is pumped out faster than it is pumped into the engine. If you watch them starting up one of these motors you will see that they crank it for quite some time before it fires up. They are watching the oil pressure to peak prior to applying fuel and spark, a normal Fuel injected engine starts after 2 revolutions of the crank once the ECU sees all the sensor signals. The turbo bearings are quite fragile I have seen turbo dune buggies lose a turbo just bouncing up over a bump and the brief lack of oil to the turbo. Also the teams cannot allow the turbo to cool down by letting the engine idle for a bit as they run the risk of overheating the rest of the engine, and a splash of cool oil on a hot bearing can cause failure as well. By keeping the turbo bearing in a bath of hot engine oil prevents them from dry start, or thermal shock thereby reducing risk of premature turbo failure. The down side oil weeps past the seal and proceeds to fog the pit lane at the next start up.

 

Actually under the lights at night the Ferrari engined cars were venting a steady stream of mist. Was this all oil? Not sure but that would be a lot of oil over a race distance.

Has the oil consumption limit gone away this year now that the crankcase venting is not allowed to be reinvested?

 

Pretty sure they use rolling element bearings (as opposed to journal bearings) so not as sensitive to momentary loss of oil pressure or low pressure at start up.

In any case, the oil we see vented out the back is from the crankcase, not the exhaust. So if oil from the turbo is leaking across the seals to the turbine, it could conceivably leak into the compressor side and so into the cylinder which is not allowed.

 

You know what, the prancing horses are truly stallions with their set up at the moment, so I for one don’t mind if they fart a bit of mist during the race, why change the horses diet when he’s winning!, do that if he starts falling at the final furlong, otherwise, hold your nose and enjoy the wins!

 

this just released today from Autosport.....provides some clarity to the 2018 rule changes regarding the breather AND the smoke on start-up.
