Ross Brawn: FIA aware one engine manufacturer can benefit more than others from Diffuser – Formula 1
Mercedes GP team principal Ross Brawn has said that the International Automobile Federation’s (FIA) double standards on Blown Diffuser use for different engine manufacturers can give an edge to some teams in the remainder of the 2011 Formula 1 season.
Brawn added that the FIA is aware of the shortcomings of their decision and their review and its findings are expected Saturday, July 9, 2011.
Brawn stated, “It is possible. I think the FIA is aware of that. Even referencing the old engine maps, if they see some things which are contrary to what they want to achieve, so if for some other reason people were using engine maps in 2009 with a lot of throttle opening, then the FIA will still ask for some explanation of why they are doing it.”
He further added, “But it is not likely people were doing it because it does use more fuel and does create heat in the system, so you would not do it unless there was some benefit.”
The review of their original decision from the FIA has come in light of the last minute inquiry from engine supplier Renault, who wanted to have more openings to ensure the reliability of their engines and to cool down the exhaust valves.
On the other hand, Mercedes engines are still not allowed to use the off-throttle blown gases as their engine uses a different technique to ensure reliability and cooling down of exhaust valves called the Over-run process.
Renault supplied teams have been allowed to use 50 percent off throttle gases to ensure the reliability of their engines. Initially, all teams were only allowed 10 percent of off throttle gas flow to ensure engine reliability. However, as Renault told the FIA that their engine needs more exhaust to ensure reliability, the rules have been changed once again.
Nevertheless, FIA’s Charlie Whiting will have a final meeting with all the engine manufacturers to finalise the decision on Blown Diffuser before the Silverstone qualifiers on Saturday, July 9, 2011.
