Study of Performance and Emission Analysis of Dual Biodiesel Fuelled on LHR Diesel Engine Supported by EGR System
Journal Title: International Journal of Mechanical and Production Engineering Research and Development (IJMPERD ) - Year 2017, Vol 7, Issue 6
Abstract
The present experiment deals the effects of Exhaust Gas Recirculation (EGR) system on the performance and emission characteristics of LHR engine using Manilkarazapota methyl ester-eucalyptus oil blends. The surfaces of the cylinder head, piston, exhaust and inlet valves of a four stroke direct injection, single cylinder diesel engine has been coated with partially stabilised zirconia (PSZ) by the plasma spray method. The coated engine was tested with the MZME30Eu70 (Manilkarazapota methyl ester 30% and Eucalyptus oil 70%), MZME30Eu70+10%EGR and diesel. The presence of EGR system creates low oxygen content for combustion and reduces the NOx emission. The graph depicts that addition of 10% EGR gives the best performance in BSEC, BSFC, BTE and emission wise when coupled with LHR engines. The brake thermal efficiency of PSZ-coated engine fuelled by MZME30Eu70 with EGR is 3.8% higher than that of uncoated engine fuelled with MZME30Eu70. Most notably NOx emission rate is decreased, by the presence of the EGR and BSFC is brought under acceptable limit.
