Impact of Biodiesel Blending on Emission Characteristics of One-Cylinder Engine Using Waste Swine Oil

Abstract

The influence of biodiesel blending on the emission parameters of a one-cylinder engine using waste swine oil was investigated in this research. This research focused on particulate matter, nitrogen oxides, hydrocarbons, carbon monoxide, and carbon dioxide emissions at various engine speeds and biodiesel mixing percentages. According to the results, increasing the amount of biodiesel in diesel blends might result in considerable reductions in particulate matter emissions while potentially raising nitrogen oxide emissions due to biodiesel’s higher oxygen content. Engine speed considerably affects hydrocarbon and carbon monoxide emissions, with biodiesel mixes benefiting more at higher engine speeds. This study also discovered that when the amount of biodiesel in a fuel blend grows, so do carbon dioxide emissions, but brake thermal efficiency drops. These findings indicate that using waste swine oil biodiesel as a fuel source has both advantages and disadvantages in terms of engine emissions, and more study is needed to optimize biodiesel consumption and reduce nitrogen oxide emissions.
