Engine Performance Tests Using Polanga Biodiesel Blends

Abstract

Abstract: In the present world it is essential to find an alternate fuel source due to the increased industrialization and depletion in natural resources. The method of obtaining biodiesel from various sources and blending them with diesel is adopted in many economically developed and developing countries around the world. This research includes the utilization of Polanga blends with diesel in CI engine. The physical properties like density, kinematic viscosity and calorific value were measured for different blend. The performance and combustion characteristics of B0, B10, B20 and B30 blends of Polanga bio diesel have been studied and it is found out that the blends of biodiesel could substitute in the place of pure diesel and be used as an alternate source of fuel in the near future, thus saving the natural resources for the future generation. Performance parameters like brake thermal efficiency, fuel consumption, brake specific fuel consumption, brake power and exhaust gas temperature are evaluated in laboratory. The emission characteristics like CO and CO2 per cent was also studied. Field performance test of power tiller with attached cultivator operated by both diesel and bio diesel was done to know the working speed, actual field capacity, average time of operation, theoretical field capacity, field efficiency, fuel consumption and energy requirement. The energy consumption for cultivating 1 hectare land was found to be 18.15 MJ/ha for diesel where as it decreased from 17.4 MJ/ha to 16.61 MJ/ha from B10 to B30. From the study, the bio diesel blend gives satisfactory result in both laboratories as well as in field test.
