Process Parameters on Performance

Economic development in developing countries has
led to huge increase in the energy demand. Thus the energy
security has become key issue for our country. Biodiesel, as an
ecofriendly and renewable fuel substitute for diesel has been
getting the attention of researchers all over the world. The
present work deals with the preparation of Corn oil methyl ester
i.e. biodiesel from raw corn oil through transesterification
process, and then its performance and emission analysis are
carried out by varying the four parameters such as compression
ratio(16,17,18,19,20) blending ratio (B20,B40,B60,B80,B100),
load (0-10) and water flow rate (50,60,70,80,90) in a diesel engine.
Significant improvements in engine performance and emission
characteristics are observed.
Corn oil methyl ester (COME) results increased NOX emission;
however the level is still lower than diesel even at high
temperatures. Also the esterified corn oil can be used in diesel
engines with reduced smoke, hydrocarbon and carbon monoxide
emissions without major detoriation in engine
performance.Biodiesel has become more attractive because of its
environmental benefits. The cost of biodiesel however is the main
obstacle to commercialization. With cooking oil as raw material,
viability of a continuous transesterification process and recovery
of high quality glycerol as a biodiesel by-product are primary
options to be considered to lower the cost of biodiesel.
