#5 of 170 Biodiesel and WVO or SVO by moparbad May 28, 2004 (9:19 am)
Diesel engine can run on biodiesel which is a product of transesterfication, waste vegetable oil, or straight vegetable oil. Biodiesel is interchangeable with petroleum derived diesel and require no different tanks or modifications for distribution or use. Using WVO or SVO requires special equipment in a vehicle. Separate tank, and heating element at a minimum and the vehicle typically uses regular diesel during the start of vehicle and prior to shut down.

It's more than $2 a gallon. Two dollars! What do those big, heartless oil companies think they are selling us? Bottled water?

#9 of 170 Does anyone know the emissions profile of biodiesel by bhill2 Jun 28, 2004 (12:17 pm)
I know that biodiesel has advantages over diesel in the emissions department, but how does a diesel engine burning 100% biodiesel compare in emissions to a ULEV or SULEV gasoline engine, or an engine running on CNG?

Replying to: bhill2 (Jun 28, 2004 12:17 pm) EPA's A Comprehensive Analysis of Biodiesel Impacts on Exhaust Emissions will help you. http://www.epa.gov/otaq/models/analysis/biodsl/p02001.pdf Biodiesel reduces Perticle Matter and CO2 but increases more dangerous NOx. 100% biodiesel blend fuel has about 10% less energy than petrol diesel. So, you are looking at energy density of the gasoline. Dennis Replies to this message: bhill2 (Jun 30, 2004 12:22 pm)

Replying to: usbseawolf2000 (Jun 28, 2004 4:45 pm) Thanks, Dennis. Although I didn't closely read all 126 pages of the report you gave the hyperlink to, the table that you included in your post gives a pretty good idea of the answers to my question. The report noted that the data were largely based on pre-1997 heavy-duty highway vehicles (largely semis I imagine)that had few emission control devices (for instance, NOX adsorbers). I wonder if the NOX increase could be prevented with such devices. Since the other pollutants decrease dramatically, and biodiesel is renewable and domestically produced, it might be worth the effort. Bob

LOOK AT WHEN THAT ARTICLE WAS PUBLISHED. IT IS GROSSLY OUTDATED. AND VERY, VERY, VERY MISLEADING. PERHAPS YOU SHOULD PUBLISH THE FOLLOW-UP ARTICLE. THE ONE STATING HOW MUCH THAT ONE PARTICULAR PLANT HAS CLEANED UP THE SMELL. I drive by that plant on the way to work every day. So there is absolutely nothing you can claim about it that I can't clarify for people. The regulators and the required action was very swift, since ethanol is mandatory in Minnesota. 100% of the gas in the metro area is a mix with gas. And because of that, we are proving the benefits from it... both from cleaner air and the fact that the production has become more efficient. BIODIESEL IS DIRTIER THAN DIESEL, WITH RESPECT TO NOx (SMOG) EMISSIONS. Would you like me to publish a link to the proof of that, again? JOHN
#13 of 170 Future fuels Ethanol vs. Biodiesel by moparbad Jul 19, 2004 (6:06 pm)
Wow, I sure hope that hybrid drivers concerned about emissions are not foolishly burning ethanol blended gasoline! http://news.minnesota.publicradio.org/features/200209/23_losurem_- ethanol/index.shtml VOC's in the news in MN. People making the ethanol choice are contributing to toxic emissions. Other problems with ethanol. Ethanol is highly volatile (increased smog from evaporation of gasoline). Ethanol can not be transported using traditional petro pipelines due to water absortion and separation from gasoline. Requires massive tax subsidies. Requires modifications to existing engines. Biodiesel is not highly volatile. Biodiesel can be transported in the same pipelines as gasoline or diesel. Biodiesel does not require blending and can be used as 100% biodiesel. Biodiesel requires no modifications to existing diesel engines. Biodiesel receives fewer tax subsidies than ethanol. Biodiesel is the smart choice for the fuel to power future vehicles, not ethanol.

hybrid advantages: 1) Lower Nox and P articulates Diesel advantages: 1) Less greenhouse effect ( esp considering fuel evaporation ) 2) No environmentally questionable battery pack 3) Renewable and net zero greenhouse with biodiesel 4) Established diesel engine longevity. Fuel economy, i think we have to say is a tossup, esp as some reviewers have claimed to have gotten the same MPG out of a prius and an (automatic) mercedes e320CDI--and that's a much bigger, heavier, and faster car. Cost--diesel, it seems. A TDI jetta is cheaper than a civic hybrid when equipped similarly, and honda is admittedly subsidizing the hybrid. Speculating that it will cost massive amounts to clean up potential future emissions standards is double speculation--euro diesel standards are already high, and diesels are cost-effective there. As i don't need a car right now, i can wait a year or two until there's an audi, c-class, or 3-series diesel available here. dave Replies to this message: john1701a (Jul 20, 2004 4:20 am)
