Biodiesel – it is a type of renewable energy, a substitute for fossil fuels that has gained interest from scientists, technologists and investors. It is used as an automotive fuel and it has similar properties to petroleum diesel. Biodiesel can be directly used in existing diesel engines with minor or no modifications. Moreover, Biodiesel would result in the reduction of emitted un-burnt Hydrocarbons (HC), Carbon Monoxide (CO), Sulfur Dioxide (SD), particulate matter in auto emission and will be in the line with the objectives of the Auto Fuel Policy of the Govt. of India.
