The attractive features of bio-diesel fuel are:
➢ It is a plant derived, not petroleum derived, and such its does not increase levels of CO2, a ‘greenhouse’ gas.
➢ It can be domestically produced and reducing petroleum imports.
➢ It is biodegradable.
➢ Relative to conventional diesel fuel, its combustion products have reduced level of particulates, carbon monoxide, sulfur oxides, hydrocarbons etc.
➢ Vegetable oils can be used in diesel engines as they have high octane number and calorific value very close to diesel.
