The Performance and Emissions of Engines Powered by Biodiesel Derived from Cottonseed Oil

There has been a rapid expansion of the use of biodiesel globally. It is consequently critical to have a comprehensive understanding of how biodiesel influences diesel engine emissions. Using mono-alkyl ester fatty acids of long-chain fatty acids as a renewable feedstock, biodiesel may be produced. Various oils and fats are sometimes used to fuel compression-ignition engines, such as animal fat and vegetable oils. An examination of several biodiesel production parameters was undertaken during the first phase of this research. An examination of blends of clean diesel fuel and biodiesel followed the first phase of the study. Transesterification is the process used to make biodiesel. Cottonseed oil is selected because of its excellent transesterification properties. The catalyst, methanol, or ethanol utilised during transesterification has an impact on biodiesel production. The presented in this article are the ideal conditions for biodiesel production. An optimal yield of 76% of biodiesel can be achieved by combining 20% methanol with 0.5% sodium hydroxide. Experiments with various biodiesel mixes revealed that they lowered particle and smoke emissions while also lowering carbon monoxide levels. In contrast, for biodiesel mixtures, emissions of oxides of nitrogen were increased slightly.
