Performance& Emission Characteristics on Single Cylinder Diesel Engine using Calophyllum Inophyllum Biodiesel

Increasing usage of automobile vehicles has resulted in exponential demand of the fuel mainly the petroleum products like gasoline and diesel oil, which are depleting very fast. Also the cost of fuel is increasing continuously. This necessitates looking for the other sources of energy like renewable sources for all transport vehicles. Biodiesel is such promising alternative source of fuel energy which can be used in conventional Compression Ignition Internal Combustion engines with little or no modification of the engine design. Though edible vegetable oils can be used for the production of biodiesel, its usage jeopardizes food supplies and biodiversity. So the non-edible oils are also thought as alternative fuels for automobiles. One such oil is Calophyllum Inophyllum oil. In this project work, experiment al study has been carried out on Kirloskar single cylinder CI engine using diesel- Calophyllum Inophyllum blend to evaluate the Calophyllum Inophyllum biodiesel as an alternative fuel for CI engine. Blends with 20% (B20), 40% (B40), 60% (B60) and 80% (B80) of Calophyllum Inophyllum biodiesel are used to study the engine performance and emission characteristics of the CI engine. The results are compared with those obtained for pure 100% diesel (neat diesel).It is observed that the performance and emission characteristics of unheated of B20 Calophyllum Inophyllum biodiesel blend i.e. 20% of Calophyllum Inophyllum biodiesel and 80% diesel fuel by volume) are found to be close to neat diesel.
