Ferrari F10 - angled engine mounting

[xpensive]

I think it's fair to assume that the crankshaft centreline, refers to the crankshaft itself, as long as there is a crankshaft.

If the crankshaft, at one point in the room, stops being a crankshaft, I guess there is no crankshaft centreline either?

The crankshaft height is set in the engine rules.

This is perhaps what you are referring to?

5.3.3 The crankshaft centreline must not be less than 58mm above the reference plane.

Ferrari can have their engine upside-down if they want to, hope the do actually.

does this sentence not imply :the centreline of the engine crankshaft has to be paralell to the reference plane??? centreline of crank does not give a starting or end point from where to take measurements,so an angled centreline does indeed
cross the reference plane somewhere...

I think it means that no part of the centerline of the crankshaft may be below a level 58mm above the reference plane. So it can slope as long as no part is too low.

there is no crankshaft but there is its centerline, as line (geometric feature) does not have beginning and the end... of course FIA court of appeal does not have to share this view

In that case, if the crankshaft centerline has no end, chances are that said centerline will eventually intersect the 58 mm line no matter how hard you try not to, when there is no such thing as zero angular tolerance.

Might take a lightyear or so, but anyway.

If the height of engine CoG is set relevant to the "reference plane", engine's position per se shouldn't matter,
Ferrari could build an engine with very low CoG and mount it higher, right?

5.4.2 The centre of gravity of the engine may not lie less than 165mm above the reference plane.

Interesting I didn't know the minimum COG height was specified. Seems to take a lot of fun out of designing

Anyway how does the FIA check this rule really?

To create more room for a larger double diffuser, the F10 has its engine is mounted at a 3.5 degree angle (1). As a result, the exhaust pipe vents are located nearer the front of the car (2) than before, creating more space for a large chamber on the central diffuser. Interestingly there is a historical precedent for this approach - back in 1970, Arrows designer Tony Southgate mounted the engine of the sophisticated A2 at an angle of four degrees (bottom drawing).
