Saving Money and Saving the Environment Knowing the Biodiesel efficiency
Biodiesel efficiency is the term used to know the effectiveness of biodiesel in certain cases. Many researchers are doing more studies to improve the overall performance of biodiesel. And there are still a lot of studies to be done not just to make the biodiesel as an alternative to petroleum diesel but to replace it.
When we talk of fuel efficiency of biodiesel, in some cases it shows better performance than of petroleum diesel because biodiesel reduces engine friction. For vehicles running on biodiesel, biodiesel contain about 10 percent less energy per gallon than diesel fuel.
Biodiesel performance shows a slight difference in energy showing a bit lower. But a higher cetane number as compared to average diesel fuel used around the globe.
Biodiesel has approximately 12 percent less energy than conventional diesel. Diesel fuel contains 42 megajoules per kilogram while as compared to biodiesel it contains only about 37 megajoules per kilogram.
The reduction of energy in biodiesel is partially offset by 7 percent average increase in the combustion efficiency of biodiesel. On average biodiesel shows a result of 5 percent decrease in power, torque and fuel efficiency. On the other hand, most vehicles that use biodiesel do not affect its performance.
So where does biodiesel get its energy? The answer is from the sun. Biofuel is a type of fuel whose energy is derived from biological carbon fixation. The primary energy of biodiesel which make up vegetable oils is from the hydrocarbon bonds.
Biodiesel can also increase the life of diesel engines because of its lubricating properties. Biodiesel replaces the exhaust odor typical of petroleum diesel with a pleasant smell.
Biodiesel efficiency testing is done by researchers to increase the overall performance of biodiesel. Tests show that using biodiesel as fuel to vehicles reduces Greenhouse Gas emissions. Biodiesel’s exhaust is free of lead, halogens, sulfur dioxide, and has reduced particulates, carbon dioxide, unburned hydrocarbons, and carbon monoxide.
Compatibility of biodiesel in some engines must be observed. In certain cases biodiesel can affect the fuel hoses and fuel seals of an engine over time. A research done by the Agricultural Research Service involving mixing additives with biodiesel could solve the problem.
When we say biodiesel blend it means a mixture of biodiesel to diesel fuel. A mixture of 5 percent biodiesel and 95 percent diesel is known as B5. While a mixture of 20 percent biodiesel and 80 percent diesel to conventional diesel is called B20. But it can be a pure biodiesel and it is called B100.
When talking of performance of biodiesel blends for example B20 often times there’s no modification or maybe minor modifications are made to engines that uses this kind of fuels.
B20 is also appealing for fleet use because it reduces emissions and is reasonably priced. But there is a minor issue concerning the use of pure biodiesel, which is its ability to degrade different types of elastomers in certain engines. Fuel pump seals and rubber fuel hoses has to be swapped with elastomers that can fit them perfectly.
