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.

Advancements in In-Cylinder and After-Treatment Strategies for Mitigating Pollutants from Diesel Engines: A Critical Review

“…However, with long-term use, serious issues arise, such as those arising from oil thickening, injector depositions, and cold start in winter seasons, are observed. These small variations add up to alterations in performance and emissions of biodiesels. , The higher oxygen and aromatic content in the fuel, the higher the combustion temperature along with a high cetane number, and viscosity, with high bulk modulus being inherent characteristics of most biodiesels, and these just happen to be the properties triggering NO x formation …”

Investigation of the Impact of Castor Biofuel on the Performance and Emissions of Diesel Engines

“…It can be obtained from plants, animal fats, and waste edible oils [3]. Compared with diesel, biodiesel has an oxygen content of around 9-12%, which can effectively reduce the exhaust emission temperature and CO, HC, smoke, and other exhaust emissions [2,4,5]. Polycyclic aromatic hydrocarbon emissions (PAH) are hazardous due to their toxicity, and biodiesel does not contain aromatic compounds, which can reduce the emission of toxic gases [6].…”
