Summary:

In this study, an attempt was made to investigate the influenceof Iron Oxide Nano particle on the performance, emission andcombustion characteristics of Low Heat Rejection (LHR) dieselengine operated with methyl esters of Waste Cooking Oil (WCOME). Inthe first phase of the work, single cylinder, direct injectiondiesel engine test rig was developed and tested for its baselinereadings with diesel at different power output. In the second phaseof the work, test engine was operated with WCOME and tested for itscharacteristics. Test engine was modified to operate in the LHRmode in the third phase of the work. Engine's cylinder head,valves and piston crown were coated with lower thermal conductivitymaterials namely, 200 microns of Yttrium Stabilized Zirconia and100 microns of Nickel, Chromium and aluminium alloys. LHR enginewas tested with WCOME and tested for its characteristics in thefourth phase. Finally WCOME was blended with 50 ppm of iron oxidenano particle (WCOMEN) and tested for its performance in LHR engineand results were compared. It comes to know that, inclusion of theIron Oxide Nano particle has significantly improved the stabilityas well as the viscosity of the WCOME. This has been clearlyreflected in the engine's characteristics operated with WCOMEN.BTE of the LHR engine operated with WCOMEN was found as 30% whichis quite higher than WCOME and near to diesel fuel operated withunmodified diesel engine. All the carbon based emissions were foundto be reduced with WCOMEN in the LHR mode. It could be due to thecombination of thermal barrier coating and presence of iron oxidenano particles which ensures complete combustion of injectedWCOMEN. However, it is interesting to note that, even with LHRmode, Oxides of Nitrogen Emission was on the higher side withWCOMEN. Thus it can be concluded that, diesel engine can beoperated with WCOMEN in LHR mode for better performance andemission characteristics with a penalty of increased oxides ofnitrogen emission. Finally, inclusion of Iron Oxide nano particleshas significant impact in the flow properties of WCOME and helpedto improve the engine's characteristics.
