Experimental Study On Performance And Emission Of Diesel Engine Fuel Blended With Iron Oxide Nanoparticle Additives

Abstract

Energy Scarcity, Pollution, And Performance Are The Big Current Issues Due To The Growth Of The World Population And Consumption Of Energy. Availability And Effective Energy Conversion Are The Key Issues That Directly Influence Any Nation Socioeconomic Status. The Diesel Engine Is One Of The Energy Conversion Devices Widely Used In Transportation Sectors. However, Its Thermal Conversion Effectiveness Is Low Due To The Low Thermal Conductivity Nature Of Diesel Fuel And High Thermal Losses During The Process. Various Researchers Improved Thermal Properties Of Diesel Fuel By Combining With Antiparticle To Increase Its Thermal Conductivity And Hence, Combustion Efficiency. Adding Nanoparticles, Particularly Iron (Iii) Oxide Nanoparticles, To Diesel Fuel Can Augment Performance, Minimize Emissions, And Reduce Fuel Consumption. However, Inappropriately Increasing The Concentration Of Iron (Iii) Oxide Nanoparticles Can Affect Engine Performance And Increase Emissions. This Is Due To The Reduction In Convection Heat Transfer, Sediment Formation, And Calorific Value Reduction. Thus, The Objective Of This Study Was To Investigate The Optimal Concentration Of Fe2 O3 Nanoparticles In The Diesel Blend Fuel. The Mixture Of Iron (Iii) Oxide Nanoparticles Blended Into Diesel Fuel Was Prepared Using Three Different Concentrations (50 Ppm, 100 Ppm, And 150 Ppm). Tween80 Surfactant Was Added To The Mixture For Stability, And Various Characterizations Were Conducted To See The Particle Distribution Within The Diesel And To Control Sedimentation. Increasing The Load Up To25 Kg, Brake Torque And Brake Power Increased, While Those Above 25 Kg Decreased. The Specific Fuel Consumption Sfc Decreased Up To A Load Of 25 Kg And Decreased Above 25 Kg. Additionally, The Exhaust Gas Temperature Linearly Decreased As The Load Increased. A Compression Ratio Of 16 Demonstrated Improved Performance Compared With 15 And 17Compression Ratios. At 150 Ppm Fe2 O3 Nano Diesel Blend, Reduced Uhc Emissions By 29.20%At 0 Kg Load, Increased Egt By 36.0% At 50 Kg Load, Reduced Sfc By 27.88% At 25 Kg Load, And Reduced Nox Emissions By 20.8% At 75 Kg Load. Compared To That In The Case Of Diesel Fuel Alone. At 100 Ppm Fe2 O3 Diesel Blend, Reduced Harmful Emissions By 37.5% For Co At 0 KgLoad And By 33.0% For Co2 At 75 Kg Load. Also Increased Brake Torque And Brake Power By30.0% And 24.0% At 75 Kg And 25 Kg Loads, Respectively, Compared With Diesel Fuel Alone. In Conclusion, The Optimum Concentration Of Fe2 O3 Is 100 Ppm For Both Emission Reduction And Performance Improvement Cases.
