What are your thoughts on biodiesel vehicles? Are they in our future? Will french fry oil finally have a good home?
#2 of 170 Nasty old grease
May 25, 2004 (5:35 pm)
What is the byproduct of biodiesel?
Surely if I stop by the local Taco Bell and get their nasty old grease for fuel and pour it into my car something will be left behind.

I've heard that biodiesel fuel is not a good choice for easy starts so it's best to use regular diesel fuel for the first few minutes then you can switch to biodiesel, true and if so how that accomplished ?
#4 of 170 Two fuel tanks

Refer to post #498 at Hybrids vs. Diesel thread for a good explanation of how to switch between diesel and cooking oil. Expensive to install an extra fuel tank, but you might get the used cooking oil free from some restaurants. As for biodiesel, you would just use the existing tank, no problem. However biodiesel blends up to 20% are recommended rather than running 100% biodiesel, from what I have read. I would add that I have no personal experience with this.
#5 of 170 Biodiesel and WVO or SVO

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.

There isn't enough free used cooking oil / soybean oil for us all but kinda like hybrids bio-diesel is there for those willing to look for it - snip - Ostaszewski: Driving the global economy on french fry oil - Have you seen the price of gas lately? It's more than $2 a gallon. Two dollars! What do those big, heartless oil companies think they are selling us? Bottled water? Milk?

#9 of 170 Does anyone know the emissions profile of biodiesel
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?

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.
