Biodiesel fuel is becoming a popular alternative to regular gasoline and diesel that we all buy at the corner gas station. As biodiesel can be blended with diesel in any concentration, the blend level depends on economics, availability, the desired emissions level, material compatibility and combustion characteristics.
In cold place weather, water freezes to form ice crystals which accelerate the gelling of the residual fuel. This fuel is made out of vegetable oil and costs considerably lesser than the conventional fuel. The main problem with bio-fuels today is the source of the raw materials.
It can be used in compression-ignition, diesel engines with little or no modifications. Biodiesel is outcome of the process called transesterification. Biodiesel has been proven to perform similarly to diesel.
Diesel engines were in fact originally designed in the early 1900's to run on biodiesel made from oil seed crops and not to run on petroleum-based diesel. More information is needed about the potentially destructive elements of first-generation biofuels and the impact they have on the environment.
