Experimental Investigation Of The Effect Of Jatropha Straight Vegetable Oil (Jsvo) Fuel On Small Scale Diesel Engine Lubricating Oil Properties And Hardware

Abstract

Current Demand Of Transport Fuel Requires Exploring Every Possible Plant Resource Of Engine Fuel Which Can Deliver Satisfactory Performance, Emission, Combustion And Engine Durability. Straight Vegetable Oil (Svo) Is An Alternative Fuel Of Petroleum Diesel, And Mainly Used To Reduce The Environmental Impact Of Emission Without Modifying Engines. Until Now, Much Of The Primary Research Has Focused On Process Technologies To Produce Straight Vegetable Oil As A Fuel From Different Sources Such As Palm, Sunflower, Rapeseed And Jatropha Curcas. There Have Also Been Studies Looking At The Impact Of The Use Of Svo On Exhaust Emission, Engine Performance, And Fuel Economy And Fuel System Compatibility. There Is Limited Data On The Effect Of Svo Use On Engine Lubricant Which Is Necessary To Investigate Usability Of Different Fuels And Their Impact On Engine Hardware And Lubricant Properties Due To Oil Contamination In Combustion Engines Which May Affect The Critical Components And Functions Of Lubrication Necessary To Maintain Engine Performance And Useful Service Life Of The Engine. This Research Work Presents Experimental Investigation Of The Effect Of Jatropha Straight Vegetable Oil (Jsvo) Fuel On The Engine Lubricant Properties And Hardware. An Endurance Test Were Made According To Is:10000 (Part Ix)-1980 ForA Total 75 Hours On Two Brand New Identical Robin Dy23-2d Air Cooled Single Cylinder Diesel Engines With Two Types Of Fuel (Jsvo And Diesel Fuel) While The Engines Use The Same Engine OilSae 30 According To The Manufacturer Recommendation. The Engine Oil Samples Were Drawn At Interval Of 25 Hours And Tested With Astm Standard Test Methods D93, D189, D445, D482,D947, D2270, D2709 And D4052. The Test Results From The Engine Oil Sample Were Analyzed ForThe Basic Lubricating Oil Properties (Kinematic Viscosity, Viscosity Index, Density, Carbon Residue, Water And Sediment, Total Acid Number, Flash-Point And Ash Content) And It Is Found That The Variation In These Properties Not Much With Jsvo When Compared To Diesel And The Viscosity Of Oil With Jsvo Is Within The Range Prescribed For Lubrication Oil Sae 30. So It Can Be Conclude That Usage Of Jsvo Doesn?��?T Affect Much The Lubrication Oil And It?��?S Possible To Use Jsvo As A Fuel. From The Analysis Of The Wear It Is Observed That The Wear Of The Parts In Combustion Chamber Are Higher For Jsvo Which Is Due To High Carbon Deposits.
