Abstract

Increasing consumption of petroleum fuels all over the world and limitations to the extraction of it has led to measurable increase in its prices per liter. Also, a concern towards its environmental effects is limiting its use. This is asking for an alternate fuel source which will provide a comprehensive solution. Biodiesel is one of the alternatives which are being widely studied. Production of biodiesel from oil seeds is limited by crop land displacement. Production of biodiesel from algae is a promising option. As it is cultivated in ponds, there will be no crop land displacement and its yield is more than that of oil seeds. The present work aims to focus on the performance of a diesel engine with algae oil as fuel. In order to use the oil in engine, its blends with the petroleum diesel were prepared. The properties of algae oil and its blends were tested and the results were compared with properties of neat diesel. It is found that, the properties of neat algae oil and its blends are very close to the properties of neat diesel. Also the calorific value of the blends of algae oil is very close to neat diesel. The results of the tests are inspiring for the aim of this project. The prepared blends were used to run a variable compression ratio engine and its performance is studied. The result shows small reduction in torque, brake power and brake thermal efficiency. Also the specific fuel consumption increases with increase in blending ratio. The emissions of CO, CO2 and HC decreased with slight increase in emission of NOx. B10 blend shows good overall result. However it can be concluded that, algae biodiesel can be blended with straight diesel up to 20% to use in a diesel engine without any modification.
