New biodiesel from neem oilhas a higher viscosity and density than conventional petroleum-derived diesel fuel. It has a lower energy density or calorific value. However, neem biodiesel mixed with petrochemical diesel fuel up to 20% by volume produces a product with a viscosity very close to that of conventional diesel fuel, making it more suitable for use in internal combustion engines.
The mixed bioproduct had little effect on the specificbrake fuel efficiency. However, this reduced smoke and also resulted in lower carbon dioxide emissions. These are two important factors when choosing biodiesel over petrochemical diesel. In particular, analysis of the generated carbon dioxide shows that the use of 20% biodiesel biodiesel neem resulted in savings of more than 0.14 kg of carbon dioxide emissions per kilowatt-hour of energy generated. Thus, neem biodiesel has the potential to become a green fuel.
