Ban on Diesel-powered motor cars in Brasil ...

If you're looking for an example of the widespread use of Ethanol today, then take Brasil. There, it is mandatory, that at least 25% Ethanol must be mixed into their fuels. Almost 90% of all new vehicles run on mixture made up of 95% Ethanol and water, which is made from sugarcane. This is an enormous promotional program, to get them away from using crude oil. Oddly enough, it was in Brasil that an alliance between six mineral oil companies was drawn up, which guarantees the State 40% of the income from the off-shore deep-wells.

Even the spark plugs must be protected ...

Ethanol is not as uncomplicated as e.g., petrol. This is why all the parts of the injection system that come into contact with Ethanol, have to be specially protected when a high percentage is used. Pure Ethanol (E100), can also be used at temperatures of -15C to start an engine, without the help of petrol. Then however, it has to be heated, for example, by glow-plugs in the distributor pipe. The controlling of an Ethanol system also appears to be more difficult.

Cellulose-Ethanol from wood ...

Another point to consider, is that Ethanol has a great future ahead of it, since at the moment, it's the only liquid fuel made from renewable sources. It's effectivity also shows good results as far as the converting the amount of energy necessary for the production, into mechanical energy is concerned. What still has to be done, is a consensus has to be found, between the production of Ethanol and the production of foodstuffs.

EU-Ethanol-production has increased sevenfold in 5 years.

The way that Ethanol behaves with water is also interesting, this also influences the mixture of premium petrol and Ethanol. If the mixing ratio between Ethanol and water amounts to 96,5- to 3,5 Vol%, then the common boiling point is around 78C. Substances having the same boiling point cannot, e.g., be separated through distillation. A little more than 4 Vol%, that is the amount of water that the hygroscopic Ethanol takes on, if it gets the chance.

Basically, Ethanol should be water-free at the filling station.

Should Ethanol and premium petrol be mixed, the latter is not mixable with water. One can e.g., determine whether there is (too much) water in the tank, a distinction can easily be made by dribbling it onto a paper filter. So, the petrol does not take on any water, the Ethanol does, in both E10 and E85. If both E10 and E85 are sated with water and then mixed together, water can even be diverged because together with the mixing, the solubility is altered. 10/13

Basically one could remove water from the tank with E85.

Indeed, even a one-off contact with Ethanol has a lasting corrosive effect.               Top of page               Index
