While looking closely at biodiesel fuel, you will find that its chemical and physical properties are extremely similar to all of the petroleum based diesel fuel, in relationship to its operation within the diesel or compression ignition engines. Because of this, biodiesel may be used within diesel engines without all of the other expensive alterations to the fuel system or engine. In addition to all of the savings in cost, there are several other notable benefits of using the biodiesel that includes:

1. Biodiesel fuel is non-toxic, biodegradable, and essentially free of aromatics and sulfur.

2. Biodiesel fuel is safer to transport and handle.

3. Biodiesel fuel has less noxious emissions than when compared to the diesel that is petroleum based, and it virtual eliminates acid rain which causes sulfur dioxide.

4. Operates in any unmodified, conventional diesel engine.

5. High octane number.

6. Improved lubricity.

7. Improved conductivity especially when compared to the ultra-low sulfur form of diesel fuel.

Overall, the best advantage of biodiesel fuel is going to be that it is a renewable fuel source, whereas all of the petroleum fuels are considered to be limited. For this reason alone, biodiesel fuel has a steadily increasing popularity.

The Disadvantages Associated With Biodiesel Fuel

1. Lower energy content: Neat biodiesel fuel has an energy content that is eleven percent lower than the energy content of diesel fuel that is petroleum based, which results the engine operation experiencing a power loss. In turn, the engine adjustment that is required for power losses may lead to violating the anti-tampering provisions of the EPA.

2. Engine operation problems: All of the engines today are designed in order to operate on petroleum fuel. The higher percentage and neat biodiesel fuels may cause a wide variety of several different engine performance problems, which includes: injector coking, fuel filter plugging, sever degradation of engine lubricant, elastomeric seal hardening and swelling, and piston ring breaking and sticking.

3. Handling and Storage: The long-term storage problems are known to occur from the biodiesel fuel's poor oxidation. When at low temperatures, biodiesel fuels may thicken and plug the fuel filters. Biodiesel fuel is also subject to microbial growth which causes fuel system corrosion, operation problems and premature plugging of the fuel filter.

Overall, these are the advantages and disadvantages that are associated with biodiesel fuel. In the event that you are interested in learning more about biodiesel fuel, there is a ton of information online that you are able to use as valuable resources. Online you will be able to find any information you could ever imagine about biodiesel fuels, you just have to make sure that you take the time to read it carefully until you understand each aspect.
