Abstract:

The modern world needs an innovative solution in the non-renewable energy field, because of its excessive usage. Due to rapid reduction of non-renewable energy sources, along with rising demand for energy is a matter of serious concern. This paper provides a better solution for this non-renewable energy problem. It is a hybrid technique in the energy field with good quality by decreasing the pure content and increase the subordinate content which must have the similar property of pure content. Biodiesel generally derived from the biological source and it can be used as an alternative fuel for diesel engines, because it has certain unique property like diesel. Biodiesel can be used as a direct replacement of diesel fuel or it also can be used as a blending element for diesel fuel in a compression ignition engines. In this paper, the biofuel called Calophyllum Inophyllum oil can be effectively blended with diesel through transesterification process. The Calophyllum Inophyllum blended with diesel at various proportions such as 20%, 40%, 60%, and 80% are tested for performance and emissions in a single cylinder variable compression ratio four stroke diesel engine test rig. The experimental results show that for 80% blend with a compression ratio of 18:1 has increased the performance of the engine, particularly the brake thermal efficiency and the CO and smoke emission levels are also found to be reduced considerably when compared to existing diesel fuel.
