The Grand Prix Commission, composed of Messrs. Carmelo Ezpeleta (Dorna, Chairman), Claude Danis (FIM), Herveå« Poncharal (IRTA) and Takanao Tsubouchi (MSMA), in the presence of Ignacio Verneda (FIM Sports Director) and M. Paul Butler (Secretary of the meeting), in a meeting held on 18 September in Alcan~iz (Spain), unanimously decided the following:
1. MotoGPclass:2011 Regulation for fuelpressure
In the MotoGP class the maximum permitted fuel pressure is 10 Bar, at a recirculated flow rate of 50 litres/hour.
1) It is mandatory to use an official approved fuel pressure regulator, as specified by the Technical Director. This official regulator must be fitted downstream of the fuel pump, such that the maximum fuel pressure available to the injectors is never more than 10 Bar.
The official regulator manufacturer may supply regulators set at any lower pressure and/or any higher flow rate, as requested by MotoGP teams, provided that these regulators are not capable of delivering more than 10 Bar at 50 litres/hour.
2) Additional regulators may be used in conjunction with the official regulator to further reduce and control fuel pressure, but no device or strategy capable of increasing fuel pressure at the injectors above 10 Bar may be used anywhere in the system.
3) The approved fuel pressure regulator will be sealed, marked and certified by the regulator manufacturer, and may be inspected and/or removed for testing at any time by the Technical Director.
4) Teams must supply a schematic diagram of their fuel system including the location of the fuel pressure regulator when requested by the Technical Director
5) In measuring the fuel pressure and flow rate delivered by the regulator, the tolerance as specified by the offical approved regulator manufacturer will be taken into account.
2. Events chedules 2010:
It was also decided that the Portuguese GP on October 20th and the GP of Valencia on November 5th, will have Friday morning practice sessions. 125cc and Moto2 classes will hold 40 minute sessions, while the MotoGP class will have 45 minutes.
