In this study, aluminum particles were added to diesel fuel in amounts of 75 and 150 ppm, with a particle size of 15 micrometers and a purity of 98.95 %. A magnetic stirrer was used to achieve homogeneous mixing of aluminum particles in diesel. In order to prevent aluminum particles from settling, fuel mixtures were stirred for 45 minutes for every 2 kg of fuel mixture. Fuel mixtures prepared to prevent settling were used immediately to avoid affecting the experimental results. The experiments were conducted at torque values of 100, 150, and 200 Nm, with a constant 660 rpm. The experiments initially started with pure diesel. Then, they continued with diesel fuels containing 75 and 150 ppm of aluminum additives, respectively. Positive effects of aluminum addition on engine performance were observed. The highest efficiency was obtained with the fuel containing 75 ppm of aluminum additive. The fuel with 75 ppm of aluminum additive provided efficiency increases of 4.57 %, 2.90 %, and 2.23 % compared to pure diesel at torque values of 100, 150, and 200 Nm, respectively. Although the fuel with 150 ppm of aluminum additive showed less efficiency improvement compared to 75 ppm, it still provided efficiency improvement compared to pure diesel. Improvements in NOx, CO, and HC emissions were observed in experiments conducted with aluminum particle-added fuels. The aim of this study is to increase the efficiency of diesel engines and reduce exhaust emissions by using aluminum particle additives.
