Effect of Using Borax Decahydrate as Nanomaterials Additive Diesel Fuel on Diesel Engine Performance and Emissions

In this study, borax decahydrate as a fuel additive was studied in a diesel single-cylinder engine. Borax decahydrate was dissolved in 500 ml of methanol, 5 gr, 15 g and 25 g, and methanol was added 10% to diesel fuel. To be 90% Diesel + 10% Methanol (D90M10) 90% Diesel 10% Methanol + 1 g Borax decahydrate (D90M10B1) 90% Diesel 10% Methanol + 3 g Borax decahydrate (D90M10B2) 90% Diesel 10% Methanol + 5 g Borax decahydrate (D90M10B3) four different fuel mixtures were tested. The experimental test measured in-cylinder pressure, heat release rate, fuel consumption, power, torque, exhaust gas temperature, smoke opacity, and exhaust emissions. Due to the rich oxygen content of borax decahydrate, it has been observed that it provides a reduction in emissions, excluding NO x emission. There was an increase in exhaust temperature, NOx and CO 2 emissions and a serious decrease in HC, CO, brake specific fuel consumption and smoke opacity values
