Influential study of oxygenated additives in waste cooking biodiesel blends on diesel engine performance

The rapid increase in energy demand brought on by the global population boom has led to a surge in the popularity of recycling waste materials into usable energy sources. That is to say, turning trash into usable energy will soon be a hot topic. More and more people are becoming aware of the benefits of biodiesel as a way to lessen their environmental impact by replacing their regular diesel fuel with a cleaner alternative. Usually, biodiesel is produced by mixing vegetable oils with animal-based oils. Because of its low production cost and low environmental impact, waste cooking oil (WCO) is suitable for biodiesel research. Using oxygenated fuels appears to be a practical strategy for lowering engine pollution. The purpose of this study is to examine the effects of varying amounts of diethyl ether (DEE) additives and waste cooking oil biodiesel on the efficiency and emissions of a diesel engine. Emission parameters were evaluated in comparison to those of pure diesel, and results were optimized for various load conditions and mixtures of oxygenated additives. The engine efficiency of WCO and DEE blends of 20% was found to be around 5.2% greater than that of standard diesel, while fuel consumption was reduced by 15%. Additionally, additives lowered CO emissions by 7-9% and HC emissions by 9%. The data were subsequently evaluated using the design of experiment tool, "Full Factorial Design" to establish the most optimal running condition with fuel consumption of 0.2720kg/kWh, hydrocarbon of 50ppm and carbon monoxide 0.277% at maximum load circumstances by the 20% fuel mixes.
