Characterization of corn oil biodiesel and its application in diesel engine

Present paper deals with preparation, characterization, and application of biodiesel (BD) prepared from corn oil by using transesterification process. As prepared corn BD is characterized by CHNS, FTIR, (NMR)-N-H, and GC-MS analysis and its properties are compared with fossil diesel. Based on CHNS analysis of BD, high C/H ratio (1.898) and low O/C ratio (0.06445) is obtained and empirical formula of BD is CH1.898N0.000322S0.000047O0.06445. Four-stroke, single cylinder diesel engine coupled with hydraulic dynamometer is experimentally tested by blending mixture (BM) of variable BD composition of BD with fossil diesel. Based on diesel engine performance, among the seven different blended mixtures of BD, BM containing 25% BD is the most efficient composition of BD in BM at all loading conditions (1?5 kg).

Automated summary

This paper discusses the preparation, characterization, and application of biodiesel (BD) derived from corn oil using a transesterification process. The properties of the prepared corn BD were analyzed using various techniques and compared with fossil diesel. The experimental results show that a blend mixture (BM) containing 25% BD is the most efficient composition among the different blended mixtures of BD, based on diesel engine performance.
