The FIA will remain tough. The active blowing of the subfloor for the gas wegnehmen should be completely banned from the GP of England. Already at the next race in Valencia, finally to be with the extreme skill settings. Red bull is against it. Now all of the written confirmation from Paris is waiting for.
It was a long meeting in London. Technology heads and FIA Race Director Charlie whiting were hot on the subject of the angeblasenen diffuser heads. Whiting quickly made it clear that he intended to prohibit all forms of Anblasens in the gas wegnehmen from the GP of England on 10 July. Single admission: when no accelerator pedal position, throttle valves (Renault, Ferrari) must or roll pusher (Mercedes, Cosworth) 10 percent remain open. Injection and ignition must be interrupted but completely.
Red bull was against the plan. You offered a compromise that you should allow at least the version of "cold" Anblasens to the end of the season. Thus air will be pumped still through the combustion chamber to to maintain the flow of gas in the exhaust in the drag of the engine. Ferrari refused that. If already ban, then complete. Consider the engine manufacturer, the engine temperatures rise at a total ban, were wiped out by the FIA. The engines would have also survived in the years 2008 and 2009. And in principle are the engines that same as it once was, because the development has been frozen since then.
The FIA went even a step further. She wants procedures that prohibit Ferme motor characteristic fields in the starting at the next Grand Prix in Valencia. Thus, the same settings as in the qualification tests would have to be driven in the race. That would hit above all those teams, that aggressively pursue the "hot" blowing and generate short term extra downforce in the battle for the best places on the grid. Means are Red Bull and Renault. How much is that, in the opinions vary. Experts speak of three to five tenths.
The extreme settings with injection and Spatzundung keep out engine and exhaust for a maximum of one or two hot laps in the training. In the race so far had to be reprogrammed to zivilere identification fields. Yet because of petrol consumption, which can rise up to 10 percent. Would we practise it in the race, the entire aerodynamic advantage would be again been eaten by 15 kilograms more gasoline in the tank. This is one of many explanations, why Red Bull was so far so exorbitantly faster in practice than the competition, then regularly came under pressure in the race. If the FIA come true power their threat, then special qualifying Setup would no longer possible in Valencia. Red bulls opponents hope that also the silver bullet would defused by Sebastian Vettel and Mark Webber.
All now wonder what impact would such banning. Generally, the cars will be critical to drive, because the brake or gas wegnehmen the current in the diffuser is no longer angefuttert by exhaust gases. The output will vary, which could cause some Turners in the brake zones. First of all, lose all time when the gas flow in the diffuser is interrupted. As a last team Hispania in Montreal had introduced the angeblasenen diffuser. Since there are more of there no protest noise. Only the "cold" blowing to brought according to the mouth of exhaust between five and eight-tenths. In the "hot" blowing relies, entirely on estimates because no one knows exactly how perfect the individual teams dominate this technique. It is certain that Red Bull, Renault, Lotus, McLaren, Mercedes, with losses to force India and Ferrari. Only they have used the trick with the "hot" blowing at all.
Engine manufacturers have to program their characteristic fields new to Silverstone. Almost all have tricky used the "cold" and "hot" blowing to make life easier for the engines. It is to reduce pressure in the Kurbelhaus (Ferrari), or to cool the exhaust by injecting (Renault). Generally, the temperatures in the combustion chamber and the exhaust valves will rise if not more ventilation in the drag operation. This may take some engine manufacturers more than others. Renault is the most concerned. "Our whole Standfestigkeits logistics is designed." "If we want to come up with eight engines for 19 race ends, we depend on it", a Renault engineer recently said.
Still, the last word is not spoken. The teams now wait for a written confirmation of the FIA and the exact specification what is prohibited and what is not. Writing should be sent to the weekend. Some of the objections of the teams that are press against a ban, were apparently so weighty that it wants to think once again in Union circles. FIA President Jean Todt likes conflicts out of the way and rather opts for amicable solutions. On the other hand he made it clear already clear in Barcelona at the point of "hot" Anblasens, that he wants to have this technology sooner rather than later ban. Is the gas mileage for aerodynamic benefit in the amount, and that does not fit the green policy of the Association.
At one point whiting and the twelve technology leaders agreed. 2012 Is concluded with angeblasenen diffusers. The original proposal, to set the alignment of the exhaust, parallel to the imaginary axis of the car was dropped. At the suggestion of Ferrari, the top of the page boxes which exhaust celebrates a comeback next year. Thus, it is safe provided, which can blow the exhaust gases are not in the diffuser.
