Boat Forum / Building / December 2007Bio-diesel additive
I just saw in the news today that my state is in the process or requireing all diesel fuel sold to contain 2% bio-diesel. Then push the limit to 5% in a set time period. My first thought was "Hold On". That might make sense to help with our foreign dependance on oil. But I don't like the idea of having this additive in my boats diesel fuel. Doesn't anyone know for certain the effects these bio-diesels may have on our marine diesel? Am I worring for nothing?

Brian Whatcott Altus OK >Bio-diesel offers improved lubricity. No real surprise, they still use castor oil for lube, because it is better in some ways [and not because it's cheap: it's not] Casady >>Bio-diesel offers improved lubricity. > >No real surprise, they still use castor oil for lube, because it is >better in some ways [and not because it's cheap: it's not] > >Casady It won't come as a surprise to you, I don't suppose: Castrol is called Castrol because they SOLD Castor oil. Still available - years ago, I would fill up an MGA just for the lovely smell. Though WWI pilots sitting behing castor lubricated rotaries, would throw up at times - it has an emetic effect apparently.

Heavy equipment, automotive use, and truck use have left no issues to deal with. High percentages (in excess of 50%)will cause corrosion is some steel lines and destroy rubber hoses and gaskets. But 5% should cause no issues.

I have a Daewoo L136 engine which was recently certified, following dyno trials, to run on both pure biofuel - veg oil - and bio diesel by the Dutch Maritime and Coastguard Agency. Engines are to be fitted into a dutch trawler. > I just saw in the news today that my state is in the process or > requireing all diesel fuel sold to contain 2% bio-diesel.

Bio-diesel isn't much different. >> I just saw in the news today that my state is in the process or >> requireing all diesel fuel sold to contain 2% bio-diesel.

The original Rudolf Diesel design was planned to use powdered coal. Bruce-in-Bangkok (Note:remove underscores from address for reply) > The original Rudolf Diesel design was planned to use powdered coal. But, it wouldn't work. So, he turned to peanut oil, which ran like an otto. Sorry for the pun, but isn't "automobile" a play on the Otto combustion cycle? Could nano powdered coal be made to work in a Diesel? Effectively? Efficiently?

You'd need to run about 250 RPM to make it work well.
