Already it clashes in the pot when it is hot !!

With ethanol, which is more volatile, it's going to be a party! : Cheesy:

Good idea I'll give you a full 50/50 SP / ethanol to "see" :)

With a 4 stroke, to get the best out of E85, it would be well to put Denso double electrode iridium spark plugs (TT), advance the ignition to 4 ° clockwise and enrich the mixture ... There you can go up higher than 50/50.

I drive 100% E85 (but no carbs, injection engine ...)

60 ct d '€ per liter : Cheesy: : Cheesy: : Cheesy:

But I take the personal Obamole attack at face value !!

tsss, a tease, you make it 10x stronger : Lol:

precisely and to be serious, the RON of ethanol is higher, a 50/50 mixture has a RON of about 100, of which less explosive.

the trick is that you have to enrich the mixture, but at 50/50 in general the calculus remain in their native enrichment range (via lambda probe).

Keep in mind that ethanol is a noble fuel appreciated by engine manufacturers (especially in competition). It allows advances in ignition and / or higher compression ratios (turbo if necessary), its combustion is cleaner and it cools the upper engine; in summary it allows to push the engine higher in power.

on old motorcycles, it suffices to put a nozzle barely bigger (eg + 20%) or to increase the flow a little if there are feed pumps.

What calculus ???? In 1994 we were still using good old carbs !! : Mrgreen: : Mrgreen:

If you want to push an engine, the best is methanol ... but it is crap to use!

I do not recommend methanol because it is corrosive with aluminum alloys, and it is more oxidizing than ethanol.

but gasoline / E85 blends generally work well. So there you have it, if it's fuel, you may have to change the nozzle, the trouble is that it's not adaptive, so if you want to stay on gasoline, it is better not to touch anything ...

It is above all highly flammable, volatile and carcinogenic ...

Fortunately we do not find it easily!

So we refocus where we anticipate mad max post coronavirus way?

Jancovici makes the connection between COVID, growth and climate:

doomed this interview is disarticulated by the fault of the journalist who interrupts and goes from the rooster to the donkey. It is more of a broken stick discussion than a fine analysis.

Janco is used to saying that economic crises are the consequence of oil shocks ... in 1974 I say yes.

but on this I do not approve of it very much, in particular the shock of 2008 was essentially a speculative crisis, a financial house of cards from the USA.

And the current COVID crisis is not an oil supply crisis.

Finally overall the little interview is listened to well, even if as I said, we will not find in-depth / calmly discussed things.

This is what we were led to believe ... a barrel had reached $ 150 in the summer of 2008 ... and the crisis started in September ...

Well I think it says almost everything ... I don't agree on everything either ... but I made it a dedicated topic anyway: society-and-philosophy / climate-co2-covid-energies-economy-and-growth-by-jm-jancovici-le-choc-covid-t16580.html
