A study on performance, combustion and emission behaviour of diesel engine powered by novel nano nerium oleander biofuel

In connection with the threating environmental pollution and stringent emission norms, the present experimental research studies the effect of utilizing cerium oxide nanoparticle mixed with an emulsion of nerium oleander biofuel (ENOB) on a compression ignition (CI) direct injection (DI) diesel engine. The whole probe was persuaded using a mono-cylinder 4-stroke direct injection CI engine. A novel nerium olender biofuel was extracted and esterified. Later it was converted into the emulsion of nerium oleander biofuel, that ensued in diluted oxides of nitrogen and in reduced smoke opacity emission. However it produced a marginal penalty of CO and HC emission when equated with neat nerium oleander biofuel. Subsequently, the nano particle blended emulsion of nerium oleander biofuel depicted dramatic diminution in CO, smoke opacity, HC, and NOx emission when equated with standard fossil diesel, neat nerium oleander biofuel and an emulsion of nerium oleander biofuel at various power outputs. It was concluded that the nano emulsion of nerium oleander biofuel could be used in direct injection, compression ignition engines without any hardware alterations in the engine.
