Biodiesel

[Doorman]

Returning to an earlier comment, how do the Brazilians overcome these inherent problems encountered with the use of biodiesel?

Lots and lots of info here: http://www.lowimpact.org/factsheet_biodiesel.htm I cannot vouch for it.

These above problems (cold starting, pump failure, filter bunging up) happen with SVO (straight veg oil) and WVO (waste veg oil - recovered).

 

Suspect the biodiesel in Brazil is Ethanol from sugar cane?

I believe you could be right Ships Cat, thank you.

Sno prob, Doorman. I think the confusion is common, and distinctions are muddied.

 

I don't think you can grow enough sugar cane to provide Ethanol for the rest of the planet any more than the planet can spare land to do it with rapeseed for SVO either.

 

Algae is the only way to go, and they've just about cracked it, it's about surface area and large areas are easily achievable, they defo have the algae producing fuel.

Very interesting reading and evidence of man's and woman's ability to evolve in order to sustain mobility via the combustion engine.

 

Thanks again! :-)

You mean they dont all make it in their garden sheds and take it in buckets to the Co-op

Brazil uses methanol to replace petrol; grown from sugar cane, rathet than biodiesel produced from the various veg oils.

^{My two pennies!}

 

^{I have used various oils in the past in car engines, you must have the correct type of fuel pump, on a car it was the Bosch, anything made by Lucas will end in tears, maybe not at first but give it time and it will go pete tong!}

 

^{I have used Cod liver oil, Evening primrose oil, Shark liver oil, Flaxseed oil and even flavoured oils such as lemon oil, orange oil and fruits of the forest oil... If it had oil it in i would pour it in.}

 

^{In the winter you are advised to mix with Diesel or petrol to thin it out, i have used neat all through the winter of 2011/2012 but only due to commuting 240 miles a day for work, starting the engine was hard, most mornings i had to jump start it.}

 

^{For me it was worth it, i covered over 30k miles in 6 months and would never have been able to afford the fuel, but it caused some issues with my old BMW and in the end did go boom in a big way.}

 

^{Knowing what i know, i would not run a narrowboat engine on the stuff, its just not worth the hassle.}

 

^{Plus it gets everywhere and smells, trying to keep things clean when using oil is not easy!}

 

^{Hope this helps!}
