Bio diesel fuel BDF is obtaining recognition in Japan as a renewable fuel which can be used as an alternative fuel without any modifications of diesel engine. We are making and testing bio diesel fuel (BDF) made from an alcohol (reagent methanol or industrial ethanol) and waste edible oils (soybean, palm oil, mixture of beef tallow and rapeseed oil). The test quantities of the six BDFs (methyl and ethyl esters) were processed in a batch type reactor. We experimentally evaluate a performance and exhaust emissions of a single -cylinder, four stroke direct-injection type diesel engine with no modifications operating on BDFs. Comparison of each fuel in engine performance and emission tests are reported in present paper.
