| Investigation Of Dtbp (di-tertiary Butyl) Addition Diesel-ethanol Blends Are Mixed With Peroxide At Low Ratios. Cetane Improvement Murat Ciniviz*, İlker Örs+, Bahar Sayın Kul* * Selcuk University, Faculty Of Technology, Department Of Mechanical Engineering Konya, 42003, Turkey Comments @ Hotmail.com Abstract- In This Study, The Effect Of Dtbp Addition To Diesel-ethanol Blends At Low Ratios (%1 And %2) Were İnvestigated. Performance And Exhaust Emissions Of A 4-cylinder Diesel Engine Using These Blends Were Compared With Diesel Only. These Blends Are Briefly Referred To As E10dtbp1 (10% Bioethanol, %1 Dtbp And 89% Diesel), E10dtbp2 (10% Bioethanol, %2 Dtbp And 88% Diesel), E20dtbp1 (20% Bioethanol, %1 Dtbp And 79% Diesel), E20dtbp2 (20% Bioethanol, %2 Dtbp And 78% Diesel). The Results Were Obtained From 5 Different Tests Using These Blends And Compared With The Results Of E10 And E20. As A Result, The Most Significant Effect Obtained By Adding Dtbp İs To Reduce Nox Emissions Related To Engine Design. Keywords - Bioethanol, Diesel, Dtbp, Emissions, Performance I. Introduction Diesel Engines, Widely Used İn The Transportation Sector, Operate With A High Compression Ratio And A Lean Mixture Due To Their High Fuel Economy And High Thermal Efficiency. Their Reliable Operation, Durability, Compatibility, And Low Maintenance Requirements [1]. Despite Fulfilling This İmportant Role, They Suffer From Producing Large Amounts Of Co, Hc, And Especially Nox, Pm Emissions. These Emissions Are Responsible For Environmental Pollution And Therefore İncreasing Costs And İncreasing Demand For Diesel Fuel, Are Looking For Alternative Fuels To Run Diesel Engines. Ethanol İs An Alternative Fuel Produced From Renewable Sources And Has The Potential To Reduce Pm Emissions İn Diesel Engines. However, Direct Use Of Ethanol İn Diesel Engines Leads To Some Disadvantages Such As Low Heating Value, Poor Lubrication Properties, Etc. [2]. Considering These Shortcomings, Different Applications Of Blending Ethanol With Diesel Have Been Technically Accepted As One Of Them. Research Related To Diesel Burning İn Engines Using Ethanol-diesel Fuel Blends At Different Ratios Generally States That Nox Emissions Will Remain The Same Or Very Similar. Slightly Decreasing Co Emissions, İncreasing Hc Emissions With The Use Of Ethanol-diesel Fuel Blends. Also, Higher Brake Thermal Efficiency And Lower Fuel Consumption Levels Are Due To The Heating Value Of Ethanol İn Engine Operation As Stated İn A Statement Made By The United Nations (usa), Ethanol-diesel Fuel Blends Provide A Solution To Low Heating Value, Poor Lubrication, Etc., Faced With Low Cetane Number, Making Combustion Highly Unstable And İgnition İs Delayed Longer, Which Requires More Time For The Fuel Combustion Process [1]. Cetane Number İs A Measure Of The Fuel's Auto-ignition Ability İn Diesel Engines And Varies With The Molecular Structure And Composition Of The Fuel, And Can Be İncreased By Reducing The Aromatic Content. Of The Fuel By Hydro-treating Or By Adding Cetane İmprovers. Adding Cetane İmprovers To Diesel Fuel İs A More Preferred Way To İncrease The Cetane Number Due To Cost-effectiveness Compared To Treating With Drugs [7]. Cetane Improvers Can Be Classified As Peroxides, Nitrites. Nitrates, Nitroso-carbamates, Tetra-azoles, And Thioaldehydes [8]. Dtbp (di-tertiary Butyl Peroxide) İs A Peroxide Based Cetane İmprover And İs Known To Be An Effective Cetane İmprover As Reported By Villes, Et Al. İn The 1940s [7]. Unlike Others, İt Has Not Been Widely Used Due To İts High Costs, Dtbp Has Been The Subject Of Many Studies Especially Aiming To Reduce Emissions Because İt Contains Nitrogen Compounds. Some Of These Studies Refer To Dtbp As A Cetane İmprover. Improvements Are Presented Below. Kumar And Raj Conducted An Experimental Study To İnvestigate The Effect Of 0.4% Addition Of Dtbp To Be5 And Be10 Diesel-bioethanol Blends. They Used Dtbp To İncrease The Cetane Number And Oxidation Stability Of The Blends To İmprove The Thermal Efficiency Of The Engine. Be5cn0.4% Was Quite High While Be10cn0.4% Was Quite High Similar To The Base Fuel (be0). Be5cn0.4% And Be10cn0.4% Had Higher Brake Power And Brake Torque Than Be5 And Be10 Respectively. Nox And Hc Emissions Were Reduced For The İmproved Blends At The Average Speed Range For Total Engine Speed And Co Emissions [1].
