Biodiesel Blend, Fuel Properties and its Emission Characteristics Sterculia Oil in Diesel Engine

In the wake of current energy scenario, major research is focused on sustainable energy solution with major emphasis on energy efficiency and use of renewable energy sources. Diesel engines have proven their utility in the transportation and power sectors due to their higher efficiency and ruggedness. Depending upon the availability and production capabilities, biodiesel is derived from a large variety of oilseed. Sterculia bio fuel is identified and proved to be the best alternative to the diesel engine. Laboratory tests were carried out to determine the properties like specific gravity, kinematic viscosity, cloud point, pour point, flash point, fire point and calorific value of the fuels used. The overall performance and emission tests have given good results except for the NOX component of the emission, which is a potential cause for smog and acid rain. This paper also focuses on the reduction of this component to a great extent with the implementation of a technique called Exhaust Gas Recirculation. In this method the water cooled exhaust of the engine is circulated back to the inlet manifold to crack the harmful NOX. This makes the bio diesel a completely emission free alternative.
