Just a remark concerning the Ethanol or ETBE question: in the June 2006 press kit on life-size experimentation in the Marne, doubt is not allowed, E85 is indeed ethanol, not l ETBE.

1) Voui Lumberjack :) This is what also told me a "contact" of the IFP based on the same document .... This does not prevent that E85 with ethanol does not meet fuel standards (sorry but I insist) ... According to this contact nothing will be done concretely before the end of 2007 ...

2) Yesterday was inaugurated in Paris the very first E85 pump ... in a Total station (which contradicts the document of the marl precisely) ... Mister Désmarest was able to fill up in front of the cameras to restore the Total image ...

Roof of the specéable: the pump will be put under selected for one year ... until obtaining the authorization of sale ....

to bring some water to the mill, here is a doc on e85 standards. it is intended for the company which will store it and distribute it:

http://e85fuel.com/pdf/e85_technical_booklet.pdf

we have, page 10, the vapor pressure values ​​of several fuels.

for E85, the vapor pressure given by the manufacturer is "between 6 and 12 psi at 37 ° C, or between 41 and 83 kpa"

or below the fateful 90 kpa ...


But why does this not correspond to the calculation of Christophe's barycenter (weighted average of vapor pressure ethanol-gasoline)?

the explanation of the values ​​can be found here

http://virtual.vtt.fi/inf/julkaisut/muu ... 100_03.pdf

(research report on biofuels)
(doc I sent you christophe)

in table 10, page 63, we have the properties of ethanol alone and a small asterisk (d):

(d): "Vapor pressure changes unlinearly when ethanol is added to gasoline"

: the vapor pressure of the ethanol-esence mixture is not a linear function ...

this is what we can read on page 37:

"Up to 10% ethanol blended into gasoline increases vapor pressure (RVP), but at higher concentrations the effect gradually declines"

When mixed up to 10%, ethanol increases the vapor pressure, but at higher concentrations, this effect gradually decreases.


I hope that this will close the controversy and the suspicions of ETBE ...

otherwise I don't see what else to do, apart from immolating myself with bioethanol :|

Very good research :)

Everything is now clear :)

So not linear with ethanol but with other mixtures it is linear ... strange anyway but so much the better ...

I would like to draw your attention to an intervention by Dominique Voynet at 13 PM news from France 2 on Wednesday October 11, on:

Controversy: biofuels not so green

Yep it joins Lepage's speech ... ok it's not so green but it's greener than oil isn't it?

I find that this article is a very good synthesis without demagoguery and allowing a realistic vision of the subject ... it is rare enough for that to be said!

Bravo caradisiac!

Bravo caradisiac!


to report that this company sell aftermarket ethanol kits for all petrol engines.

It is guaranteed for one year.

Someone asked for a post or find kits in France but I can't find the post.

code: Select all

I bought a lot from him and the guy is nice and always ready to help.
