Biodiesel offers similar power to petroleum diesel fuel. Biodiesel has a higher cetane number than most U.S. petroleum diesel fuel. In testing of more than 50 million on-road miles and many marine and off-road applications, biodiesel shows similar fuel consumption, horsepower, torque and haulage rates as petroleum diesel. Biodiesel provides significant lubricity improvement over petroleum diesel fuel. Lubricity results of biodiesel and petroleum diesel using industry test methods indicate that there is a marked improvement in lubricity when biodiesel is added to petroleum diesel fuel. Biodiesel levels as low as one percent can provide a 65 percent increase in lubricity. Compatibility of biodiesel with engine components. The switch to low sulfur petroleum diesel fuel has caused most OEMs to switch components suitable for use with biodiesel. Biodiesel can be used in existing engines and fuel injection equipment with little impact to operating performance. Biodiesel is considerably less hazardous than petroleum diesel. Pure biodiesel (B-100) does not ignite until 150 ° C (300 ° F), petroleum diesel burns at 50 ° C (120 ° F). Biodiesel is also significantly less toxic than petroleum diesel and is more biodegradable. This reduces the negative impacts of spills. Biodiesel is four times as efficient as diesel fuel in utilizing fossil energy. Biodiesel yields about 3.2 units of fuel for every unit of fossil energy consumed in the lifecycle. By contrast, petroleum diesel yields only 0.83 units of fuel product per unit of fossil energy consumed. EPAct Benefits. Congress approved the use of biodiesel as an Energy Policy Act (EPAct) compliance strategy. The legislation allows EPAct-covered fleets (federal, state and public utility fleets) to meet their alternative fuel vehicle purchase requirements simply by buying 450 gallons of B-100 and burning at least a 20% blend. Biodiesel’s lack of polluting emissions is the most dramatic difference between it and petroleum diesel. B100 achieves a reduction in emissions from petroleum diesel. Specifically:
