Treven,
A motor ingests air and fuel into the combustion chamber , the air contains mostly nitrogen along with the reqired oxygen for combustion . The nitrogen in the presence of combustion combines with the fuel byproducts to form nitrouse oxide and nitric acid both corrosive, if theres sulphur in the fuel there will also be sulphuric acid in the exhaust along with sulphur dioxide. Now modern engines run lower compression ratios to reduce the nitrous products in emissions , with diesels this is not possiable, hence the tightly controlled electronuc injection systems now in use on new diesels. Our model diesels welll we just still live in the dark ages, and continue to produce toxic pollutants.
Reg,
Both my cheap vegi oil and olive oils came out clear after the modification , just like andy's- maybe we cooked ours longer and drove out the excess water??
I havent contacted my bio chemist yet re specifics , I've been busy organiseing accomodation in the city for my son while he's at trade school, hope to get an email away sometime this week with a list of questions.
Andy,
Your 10% lube runs with olive oil and castor are interesting. Might the slowing and stopping with the castor be due to laquers forming due to higher combustion temps?
Castor can be stabilised to reduce/stop laquer formation by addition of SMALL amounts of vitamine "E".
Glad you gave the modded oilive oil a try Andy, its performance looks good with the benefit of easier starts with low/no ether fuels, not sure I'm game to run only 10% tho

, I did try 20% and was happy with it.
