Experimental Investigations on Performance and Emissions of a C.I. Engine Fuelled With Milk Dairy Waste Scum Oil Biodiesel

The present research work proposes to study the transesterification process of milk dairy waste scum oil and its suitability as a fuel for CI engine by conducting performance and emission tests. This study was carried out in two steps, production of milk dairy waste scum biodiesel followed by performance and emission tests on a single cylinder, four-stroke CI engine with water cooled system at a fixed engine speed of 1500 rpm and at different load conditions. The impact of milk dairy waste scum oil biodiesel and its blends as a fuel on brake-specific fuel consumption, brake thermal efficiency and brake-specific energy consumption and exhaust gas emissions has been investigated and presented. From the experimental results it is concluded that the performance and emission characteristics of B20 are satisfactory compared to all other blends. Hence, blend B20 can be used as an alternative fuel source in CI engine without any modifications in engine hardware.
