Ferrari 2014 Car Pre-launch Speculation

[Hail22]

Very much appreciated Langwadt!

To my untrained eyes (lets face it I'm no engineer) there looks to be no way to find a loophole with the exhausts, from what I understand you cannot cut into or have anything within the cylindrical exhaust housing?

So this begs the question, what can Ferrari do to find the edge against its competitors? will it be power unit based, aero based or tire management based?

Sorry for not delving deeper into the subject, but I've intercepted that Ferrari may have experimented with spark plugs with a diameter of 10 mm, which should in theory allow some advantage in cylinder and engine design?

Does anyone have more info on that? Just curious.

scarbs said something about of ferrari engine design on twitter just now
this is interesting idea, may be? https://twitter.com/ScarbsF1/status/421040446375075840 https://twitter.com/ScarbsF1/status/421037017011863552

Dont understand it. Exhaust exit is strictly restricted by rules.

I can only find:

5.1.9 Engine exhaust gases may only exit the cylinder head through outlets outboard of the cylinder
bore centre line and not from within the “V” centre.

What he is saying is the Ferrari have made the package so small that the exhausts that go out and up and to the turbo wont be so wide that they go out into the sidepod area compared to the Renault pics we have seen.

I drew the ferrari engine with exhausts exiting upwards through the heads, not through the outer face of the head. This would keep exhausts short and keep the total engine installation much narrower.
The rules only demand the exhausts exit outboard of the cylinder bores centre line, the top exit exhausts meet this rule. Similar exhaust ports have been used on the lancia delta group B car and some BMW racing engines.

Looks very interesting. But also look like a nightmare to fit an injector nozzle + a spark plug?

Lancia Engine with Triflux head/intake design

[scarbs]

thanks, I was searching for that pic, thats close to what I imagine could be used, but the exhausts would be central and the inlets on one side only.

The idea was from Monsieur Apfelbeck, google 'apfelbeck engine' and you'll see other incarnations of the design.

How much does an exhaust weigh approximately? 5-7kg´s?

Probably less than half of that for both exhausts....

Depends on what you mean by an exhaust. Do you mean one single manifold?? Both?? The intire system including the turbo??

I bet the exhausts will still be made from inconel. And that is pretty light weight. So under a couple of kg's for the intire pipework is my guess.

[SectorOne]

Both systems and from the cylinders to the turbo, should have specified it a bit more.
I was just curious if there was a CoG disadvantage (that may or may not be balanced out by the much tighter packaging) compared to a more let´s say conventional layout like we believe the other two engine manufacturers have done.

[majki2111]

Well, narrower sidepods could bring advantage in airflow. It could be better and faster. I can only se maybe less drag and nothing else for advantage. Or maybe better airflow to diffuser or maybe bringing hot exhaust gasses with air to blow rear wing?

[f1316]

Is there not also a power (or lack of power loss) advantage in having shorter exhausts?
