Performance assessment and emission characteristics of a c i engine fuelled with used cooking oil bio fuel blends and the impact of hho gas addition on combustion

Abstract

Biodiesel is a valuable alternative for diesel fuel usage and the newlineinevitable resource depletion and pollution problems of the globe. A large newlineamount of used cooking oil (UCO) produced around the world and a very newlinemeager amount of UCO is being recycled. The mankind can tap the energy newlineavailable from the UCO and can reduce the usage of petroleum products as newlinefuel for automobiles and lubricants for machinery operation to considerable newlineextent and will provide amicable solution to the economic and environmental newlineissues. The UCO can be collected from the stakeholders to reuse as a newlinebiodiesel otherwise it will end up as a waste in the sewage. newlineUCO based biodiesel production is important because it can be newlinechanged into other useable form using easy chemical treatment process called newlinetransesterification. This process provides the biodiesel with properties newlineanalogous to diesel. Biodiesel has zero sulphur content and offers a significant newlinereduction in carbon monoxide and hydrocarbon emissions. newlineUCO based biodiesel were used to improve the performance and newlineemission characteristics of a variable compression ratio (VCR) four stroke newlinemulti fuel engine. Because of their lower carbon monoxide and hydrocarbon newlineemissions, diesel and used cooking oil blends are increasingly being used as newlineprimary fuel. In this work, additional hydroxyl (HHO) gas is being introduced newlineinto the combustion process of standard diesel fuel blended with used cooking newlineoil to see the effects on brake specific fuel consumption, brake thermal newlineefficiency, and emission characteristics. newline newline
