Experimental analysis on thermally coated diesel engine with neem oil methyl ester and its blends

Research output: Contribution to journalArticlepeer-review

Abstract

Depletion of fossil fuel has created a threat to the nation’s energy policy, which in turn led to the development of new source renewable of energy. Biodiesel was considered as the most promising alternative to the traditional fossil fuel. In the present study, raw neem oil was considered as a principle source for the production of biodiesel and converted into Neem Oil Methyl Ester (NOME) using two stage transesterification process. The chemical compositions of NOME was analysed using Fourier Transform Infra-Red Spectroscopy (FTIR) and Gas Chromatography- Mass Spectrometry (GC-MS). Baseline readings were recorded with diesel, 25NOME (25% NOME with 75% diesel) and 50NOME (50% NOME with 50% diesel) in a direct injection, four stroke, water cooled diesel engine. Thermal Barrier Coating (TBC) was considered as a better technique for emission reduction in direct injection diesel engine. In the present study, Partially Stabilized Zirconia (PSZ) was used as a TBC material to coat the combustion chamber components like cylinder head, piston head and intake and exhaust valves. In coated engine, 25NOME showed better brake thermal efficiency and declined brake specific fuel consumption than 50NOME. Decreased exhaust emissions like CO, HC and smoke were observed with 25NOME in coated engine except NOx. [Figure not available: see fulltext.]
