Presently, there is a substantial worldwide need to replace fossil fuels with renewable energy sources. The greenhouse effect is considered to be one of the adverse outcomes of fossil fuels, resulting in an increase in global temperatures. Biodiesel is a feasible alternative to fossil fuels that can be produced from a variety of organic sources. Researchers are investigating the application of nano-materials to power systems in order to alter the properties of fuel in compression chambers. The objective of this project is to replace diesel fuel with a blend of diesel and biodiesel produced from waste cooking oil (WCO) by a catalytic transesterification reaction (CTR). CTR converts WCO into methyl esters by gradually adding a tiny quantity of alcohol over one hour at a reaction temperature of 65 °C. A fuel blend will be formulated to fuel a four-stroke direct injection engine, comprising 40% diesel, 60% biodiesel, and various quantities of CuO nano-material. The engine will maintain a consistent speed of 1400 revolutions per minute (rpm) without the need for forced induction, and it will experience varying amounts of workload. The experiment involved testing different fuel mixtures, including pure diesel, B40 (60% biodiesel and 40% diesel), 50b40 (60% biodiesel, 40% diesel, and 50 mg of CuO), 100B40 (60% biodiesel, 40% diesel, and 100 mg of CuO), 150 (60% biodiesel, 40% diesel, and 150 mg of CuO), and pure diesel. An investigation has been carried out to examine the impact of copper oxide on the performance of engines and the release of emissions. The experiment's results suggest that diesel engines can function with varying mixtures of fuel, biodiesel, and CuO nano-material, while keeping the same operating parameters. The collected data indicates a 10% enhancement in brake thermal efficiency, an 11.6% reduction in exhaust temperature, and a 6.66% drop in brake specific fuel consumption.
