摘要：Adding nanomaterials to diesel fuel can improve the quality of fuel combustion and reduce pollutant emissions depending on the additive. Researchers have studied many nanomaterial additives. This study investigates the effects of adding nano-Al 2 O 3 and nano-TiO 2 to diesel fuel. These nanoparticles were added to Iraqi diesel in four mass fractions (25, 50, 100 and 150 ppm). Results showed that adding the nanomaterials significantly affected the ignition and increased the maximum pressure inside the cylinder. The addition of nano-TiO 2 and nano-Al 2 O 3 also increased the brake thermal efficiency of conventional diesel from 18.9% to 24.25% and 20.45%, respectively. The maximum pressure inside the cylinder under total load conditions reached 62 bar and increased to 63.2 and 60.4 bar after the addition of 25 ppm of nano-Al 2 O 3 and nano-TiO 2 , respectively.
