Engine characterization study of hydrocarbon fuel derived through recycling of waste transformer oil

摘要: Abstract This work intends to capitalize waste transformer oil (WTO) as a renewable source of fuel in diesel engine, given the cost being used is reduced when using products. Previously, despite its higher viscosity, WTO such or blends with engine. However, current study, efforts are taken chemically treat so bring down viscosity and make it conducive for engine application. As such, pretreated concentrated sulfuric acid subjected alkaline trans-esterification an alcohol alkali catalyst. Interestingly, derived hydrocarbon (HCF) discerned presence cyclo-hexenol oxabycyclo-heptane major constituents, contrary exwastence methyl esters reported other trans-esterified vegetable oils. Subsequently, HCF utilized by optimizing combustion bowl geometry, considering that modification imperative effectively operate high viscous like In this regard, three geometry shapes preferred viz Piston 1 (shallow depth chamber), 2 (toroidal chamber) 3 (hemispherical chamber). pursuit experimental investigation B25 (HCF – 25% 75%) B100 100%), piston showed enhanced performance emission than two configurations. Notably, BTE increased 10.2%, while HC, CO smoke 13.3%, 11.7% 10.1%, respectively, conventional (piston 3) at expense NO X emission.
