Yikes. I wonder what gasoline is considered then.

Actually, according to my uncle who did his PhD on diesel engines, they run much better on ether than diesel. Of course it was $6/gallon, back when diesel was $1/gallon.... And alot of the industrial diesels for power generation are designed to run on natural gas instead of diesel, because of lower emissions and cost. I'm not sure what they do to the injection system to run a gaseous fuel in a diesel engine. > > And, furthermore, if reducing the viscosity of WVO was the primary goal of > producing BD, there are significantly simpler, cheaper, and safer ways to do > it than transestherification. Regarding the emissions of SVO, I have some EPA data from a 1974 Mercedes running on WVO that has never been published. I'll post it here if I can find it again. Some students did the testing on a senior design project that I was overseeing last year, but they didn't realize that the the test car was usually run on biodiesel blend so our base-line test might not be very meaningful. If I recall, emissions were very close to, if not higher for WVO than the base case, except for particulates, which were much less. > > Just my 2 cents, I'm not a pro. > > _______________________________________________ > Biofuel mailing list > Biofuel@sustainablelists.org > http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org > > Biofuel at Journey to Forever: > http://journeytoforever.org/biofuel.html > > Search the combined Biofuel and Biofuels-biz list archives (50,000 > messages): > http://www.mail-archive.com/biofuel@sustainablelists.org/ > > > > _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
