This is just how I understand the 2009 F1 sporting rule on engine usage.
Based on the way Article 28.4 of the
2009 F1 Sporting Code had been written, it seems that the engine changes are not dictated by
"EVENTS" anymore, unlike the way the gearbox is (with the exception of post qualifying and post-race parc ferme). I found out that unlike the 2008 sporting code article about engines, the 2009 sporting code Article 28.4 does not have a provision which defines
Events. This might mean that any
driver can interchange a total of 8 engines anytime before the start of qualifying practice or after the post-race parc ferme per GP weekend for the entire 2009 championship season. So, as long as any one of the 8 engines are still useable, they can be used as much as a driver can or wants to use it.
But, this doesn't mean that a driver can have a "dedicated engine" for use in qualifying only and a different one for the race itself without incurring a penalty. This is due to the fact that once a car leaves the pits to participapte in
Qualifying Practice, the car is already under Parc Ferme rules until the start of the race. And, Parc Ferme rules state that:
34.5 If a competitor modifies any part on the car or makes changes to the set up of the suspension whilst the car is being held under parc fermé conditions the relevant driver must start the race from the pit lane and follow the procedures laid out in Article 38.2.
Also, each time an engine is to be replaced with the intent of not using it anymore (i.e. it's completely unuseable), it counts against the 8 engines available for the
entire 2009 season. Therefore, a driver can only be penalized with the 10-place grid demotion after he exhausts his entire supply of 8 available engines. This is what's stated on the 2009 sporting code about this:
Article 28.4 a)...Should a driver use more than eight engines he will drop ten places on the starting grid at any Event during which an
additional engine is used.
@ Sawtooth-spike If a driver did completely blow/damage all of the 8 engines allocated for the entire season within the first 8 races, you will have the 10-place grid penalty at every race during the rest of the season you use an extra engine (9th engine in this case) which was not part of the original allocated 8 engines. Expanding on that line of thought, if your 9th engine had also been damaged beyond repair and you use a new, 10th engine, you'll have a 20-place grid demotion at every race you use that 10th engine...and so on. Reliability is really a big differentiator this season.
still @ Sawtooth-spike About the friday engine rule, that's what confuses me. In the official Formula 1 website it can be quoted that:
Teams will be limited to eight engines per season - eight for each race driver and an additional four for testing.
If I'm not mistaken, there is nothing in the FIA-published, 2009 F1 Sporting Code which states there is an
additional 4 engines dedicated for testing purposes. If anyone of you knows anything to contrary, please correct me.
This leads me to believe that
midzt might be correct about his statement that you can have "dedicated Friday P1/P2 engines" but these engines will still be any one of the 8-allocated engines for the 2009 season. BUT!...and this is a big "but"...There is a clause stating that if you race an engine and a driver intends to use that same engine in the next Event, the FIA scrutineers/officials will place seals on that engine at the end of the post-race Parc Ferme. Those seals can only be broken during the start of the next Event for which the sealed engine is intended to be used.
The rational for this is to avoid major part replacement/overhaul of the used engine in between the concluded race and the next Event. The confusion here is that as I've said above, Article 28.4
does not define what an "Event" means. In the 2008 Sporting Code, Article 28.4 defined an "Event" as comprising of P3, Qualifying Practice and the Race. If this definition still holds true for this season, then a driver can indeed use one of the still "unraced" engine (which is part of the original allocated 8 engines) for Friday P1 & P2.
Unfortunately, if all of the 8 allocated engines have already been raced, then the engine which a driver uses during Friday P1 & P2, will be the same engine he'll be using during P3, QP, Q1, Q2, Q3 and up to the end of the Race... assuming the engine stays working up to the end of the race.
