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. rosacea treatment 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 Fuel1. 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.
