        abstract = {The increasing demand for energy and environmental concerns has driven the search for sustainable alternative fuels. This study evaluates the performance of a compression ignition (CI) engine using a blend of 20% yellow oleander methyl ester and 80% diesel (Y20) enhanced with carbon nanotubes (CNTs). CNTs were added at 25, 50, and 75 ppm and stabilized using a non-ionic surfactant (Span 80). Engine performance, combustion, and emission characteristics were analyzed under varying injection pressures. Results indicate that the Y20 blend with 50 ppm CNTs (Y20C50) delivered optimal performance, with a 9.63% increase in brake thermal efficiency and a 20.57% reduction in brake specific fuel consumption. Emissions of hydrocarbons, carbon monoxide, and nitrogen oxides were significantly reduced. Additionally, ignition delay and combustion duration decreased, while cylinder pressure and heat release rate improved. Overall, CNT-enhanced Y20 blends show strong potential for improving CI engine performance and reducing emissions.},
