Really? Each 10 degC represents 0.5% in power? Where did you hear this news?Racer-X wrote:It is reported that each 10 degC represents 0.5% in power.
By the regulations the teams are allowed to cool the fuel up to 10degC below the ambient temperature.
For 2004 only the fuel in the pitstop tanks can be cooled and not the car tank anymore.
The big discussion in Ferrari's cooling on the grid was if there was some fuel inside the cooler before connecting it to the car.
The FIA probably found something wrong. Now it is forbiden!!!!
Italians!!!!!!
fuel becomes more dense after cooling thus giving more fuel to enter combustion chamber, computer reconizes this and adjusts fuel trims, back to programmed trims, what was accomplished?rollo wrote:once knew someone who ran his fuel line along the cold a/c pipe which returned the gas back to the A/C Compressor from the evaporator and wrapped it up with insulation. he experienced some improvement in engine power although not much.
The fuel circulate from the tank, through several fuel pumps, to the engine and most of it then back to the tank again. This can heat the fuel quite significantly, especially if a small amount of fuel is used or if no refueling is allowed. When the fuel gets warm, the cooling effect on the incoming charge decrease and there is a small loss in power. Not a big loss, a half to one percent probably if we go from say 80 degC to 40 degC but then again, there is probably also a small gain in fuel efficiency.archebald23 wrote:fuel becomes more dense after cooling thus giving more fuel to enter combustion chamber, computer reconizes this and adjusts fuel trims, back to programmed trims, what was accomplished?rollo wrote:once knew someone who ran his fuel line along the cold a/c pipe which returned the gas back to the A/C Compressor from the evaporator and wrapped it up with insulation. he experienced some improvement in engine power although not much.
