Diesel

You are so fa right, that Shell is the official provider of the ACO, as they are mentioned on the tickets, the poster, and so on.

Ah, I think I understand now, the ACO say they will supply the fuel, and Shell comes along with a couple of heavies, and says to the ACO 'We've got some fuel, which we can let you have, after all if you were to get your fuel from someone else, you never know, it's awfully flamable stuff'

Not that I'm alluding to underhand practices.

The octane ratings and make up of the fuel supplied was listed on the ACO sites rules section, it covered both Petrol and diesel.

I doubt it was pump diesel but it would have had to conform to the regs and by all coming from the one supplier means some of the more exotic brews we have seen in the past did not happen.

Rather than slow down the Diesel cars, would it not have been better to speed up the petrol cars?

There was a mention somewhere that the diesel was distilled from coal. I know the Germans in WW2 used fuel distilled from coal, perhaps with the rising oil price it is viable again.

Was not the original diesel engine designed to run on nut oil?

And how green is bio diesel.

This 12 cylinder diesel engine you won't see at Le Mans, even thou it gives out 7780 horsepower!

Tooele, Utah – IMSA today published a bulletin that affects the refueling rig restrictor of the diesel cars participating in the American Le Mans Series, specifically the Audi R10 TDI cars. The change limits the refueling restrictor from the current 38mm permitted under the regulations to 33mm, effective immediately.

"As was highlighted in today's press bulletin issued by the ACO, there is an overall desire by the organizing bodies to work toward a situation where all cars, no matter what fuel they choose to use, have the same amount of energy on board," said Tim Mayer, Chief Operating Officer of IMSA. "However, that is not the situation with the current regulations. So as an interim step, we have restricted the R10 so that it cannot receive more energy in the tank in a given time frame.

"We notified the team of this change at the Lime Rock Park event. However, because of a variety of test and calculation methods that are possible to determine the energy content of fuels, we chose to hold the public release of the bulletin until we had verification of the numbers," added Mayer.

The current regulations permit the same 90-liter tank on both diesel and gasoline cars but permit the larger restrictor on the refueling rig of diesel cars because of the different viscosities of the fuel.

"The original intent was to permit the full volume of the tanks to be filled in the same time," said Mayer. "However, diesel is a more energy-rich fuel for any given volume. The change that we have implemented means that the energy delivered will be similar, for the diesel versus gasoline, for the same length of refueling. The goal is to ensure that competitors have the opportunity to compete without a quirk in the physics of the fuels creating a particular advantage. We are currently working with the ACO to come up with a formula for tank sizes for a variety of different fuels."

They're on pole.  We'll see how the rest plays out.  Too bad the Dyson Lolas are about as reliable as an '86 Yugo.

I'm anxious to see what Miller Motorsports Park looks like.  It's supposed to be pretty sweet despite being in the middle of freaking nowhere.

The Utah Grand Prix, the fifth round of the 2006 American Le Mans Series, is set for 6 p.m. MDT on Saturday, July 15 at the new Miller Motorsports Park just outside of Salt Lake City. CBS will broadcast the race from 2 to 4 p.m. EDT on Sunday, July 16. MotorsTV will broadcast the race in Europe from 6:30 to 9:30 CET on Sunday, July 16. American Le Mans Radio will provide live coverage on americanlemans.com, which also will feature IMSA Live Timing & Scoring.
