Performance Evaluation And Emission Characteristics Of Used Cooking Oil Biodiesel Blended With Nanoparticles In Diesel Engine

Abstract

Worldwide Increases In Energy Demand And The Depletion Of Petroleum Reserves Have Risen Oil Prices And The Use Of This Fossil Fuel Causing Environmental Degradation. The Declining Petroleum Reserves And Environmental Concerns Are A Primary Problem Related To Fossil Energy. A Substitute Energy Source That Has The Potential To Be Developed In Ethiopia Is Biodiesel. Used Cooking Oil Is A Potential Feedstock For Synthesizing Biodiesel. Production Of Biodiesel Reduces Environmental Pollution And Human Health Risks. A Lot Of Previous Research Work Was Reviewed To Realize The Behavior Of Biodiesel In A Diesel Engine. Since Biodiesel Has Some Disadvantages Like Higher Density, Higher Viscosity, Lesser Heating Value, And Short Shelf Life, Etc. At Present Days With The Development Of Fuel-Borne Catalysts, Modifying Fuel With Nanoparticles To Enhance Its Properties Is Attracting The Attention Of Researchers. In This Thesis Work, An Experiment Was Conducted To Evaluate The Performance And Emission Characteristics Of A Diesel Engine Run By Biodiesel-Diesel Blend With MetalOxide Nanoparticles. This Work Proceeds Through Different Phases Such As Biodiesel Production By Transesterification Reaction, Characterization, Modified Fuel Preparation By Using An Ultrasonicator, Testing Performance And Exhaust Emission Of Sample Fuels In Diesel Engines, And Compare It With Baseline Diesel Fuel. Sample Fuels Prepared For Testing WereB100, B15, And B15 With Nanoparticles. The Engine Performance Test Result Has Shown That The Average Bp Of B15c80a40m30, B15c80a20m50 Fuel Was 3.57%, 3.08% And The Average Bsfc Of B15c80a50m20 Fuel Was 10.4% Lower Than B0. The Mean Output Bt OfB15c80a40m30 Fuel Was 2.5% Higher Than Pure Diesel Fuel. Related To Exhaust Gases Emission Test Result Has Shown That The Average Co And Hc Emission Of B15c80a40m30Fuels Was 25.7% And 20.18% Lower Than B0. The Mean Co, Co2 And Hc Emitted ByB15c80a50m20 Was 25.7%, 9.04%, And 20.2% Lower Than B0. The Average O2 EmissionsOf B15c80a40m30 And B15c80a20m50 Were 1.93% And 1.95% Higher Than B0,Respectively. From Performance And Emission Test Results It Can Be Concluded ThatB15c80a40m30, B15c80a50m20, And B15c80a20m50 Can Be Used As Alternative FuelsIn Diesel Engines, Respectively.
