Experimental Investigations on effective utilization of Waste Cooking Oil Methyl Esters in A Thermal Barrier Coated Compression Ignition Engine

Abstract

Currently waste utilization is one o the challenging tasks in the world In this study an attempt was made to effectively utilize waste Cooing Oil CO as a fuel for the compression ignition engines The investigation as arried ot in a single linder ater ooled diret inetion diesel engine it a maximm poer otpt o In te irst pase o te or te test engine as tested it CO and diesel as el at dierent load onditions s as and and aseline data as reorded In te seond pase o te std CO as onverted into its esters COME and tested at te same load onditions In te tird pase o te or engine omponents ere oated it Termal Barrier Coating TBC and tested it COME In te ort pase COME as onverted into its emlsion COMEE and tested it a TBC engine In te inal pase COME as lended it nanolids s as Iron oxide COMEN and tested in te TBC engine It is ond tat diret tiliation o neat CO reslted in inerior perormane and inreased aron ased emissions as ompared to diesel el Exast Gas Temperatre EGT and Smoe Opait o CO ere notied to e OC and respetivel ereas it as OC and respetivel it diesel el at pea load ondition oever Nitri Oxide NO emission o CO as reorded loer tan diesel el at all te load onditions On tiliing COME as el EGT as reded to OC at te pea load ondition Emissions s as Smoe Opait dro Caron C and Caron Monoxide CO ere also on te loer side as ompared to CO at all load onditions Te Pea Pressre PP and eat Release Rate RR rate o COME ere inreased as ompared to CO at all te load onditions Enanement in te perormane omstion parameters o COME is mainl de to te drasti redtion in visosit o CO ater onverting into its esters oever inreased NO emission as notied it COME as ompared to CO at all te load conditions.
