Higher Combustion Efficiency of Biodiesel

The oxygen content of biodiesel improves the combustion process and decreases its oxidation potential. The structural oxygen content of a fuel improves its combustion efficiency due to an increase in the homogeneity of oxygen with the fuel during combustion. Because of this the combustion efficiency of biodiesel is higher than that of conventional diesel, and the combustion efficiency of methanol/ethanol is higher than that of gasoline.

A visual inspection of the injector types would indicate no difference between biodiesel fuels and conventional diesel in testing. The overall injector coking is considerably low. Biodiesel contains 11% oxygen by weight and no sulfur. The use of biodiesel can extend the life of diesel engines because it is more lubricating than petroleum diesel fuel. Biodiesel has better lubricant properties than conventional diesel.

The higher heating values (HHVs) of biodiesels are relatively high. The HHVs of biodiesels (39 to 41 MJ/kg) is slightly lower than that of gasoline (46 MJ/kg), conventional diesel (43 MJ/kg), or petroleum (42 MJ/kg), but higher than coal (32 to 37 MJ/kg).
