This study investigates the performance and emission behavior of borax decahydrate nanoparticles when blended with biodiesel commercial diesel fuels in engines. Experimental tests were conducted at five different engine power levels: 1 kW, 2 3 4 5 kW-to evaluate impacts these fuel blends on performance, emissions, energy efficiency, exergy, exergoenvironmental parameters. The data collected demonstrated a general trend where higher output led to increased heat generation. Among tested blends, D40W50P1 achieved efficiencies 15.236%, 15.466%, 18.290%, 25.606%, 24.258% respective levels, highlighting positive effect nanoparticle addition performance. inclusion particularly improved diesel/waste cooking oil blends. results also revealed that D50W50 blend performed optimally whereas D40W50P3 showed notable improvement, achieving an efficiency increase 12.10%. Furthermore, sustainability index values consistently above 1, indicating favorable environmental energetic balance for all lowest recorded was 1.123, observed blend. In terms analysis, D40W50P2 carbon dioxide (CO₂) emissions 311.69 kg/month kW 786.34 kW. These highlight potential additives not only improve but contribute reducing emissions. indicate boron can enhance while CO₂ Additionally, improvement reveals boron-based from both economic perspectives. findings serve as important reference future research industrial applications related alternative additives.

With conventional fuels dwindling and emissions rising, there is a necessity to develop assess innovative substitute fuel for compression ignition (CI) engines. This study investigates the potential of magnesium oxide (MgO) nanoparticles as sustainable additive enhance performance reduce used cooking oil (UCO) biodiesel–diesel blends in CI MgO were biosynthesized using Citrus aurantium peel extract, offering an environmentally friendly production method. A single-cylinder engine was test diesel (B0), 20% biodiesel blend (B20), B20 with 30 ppm (B20M30) 60 (B20M60) nanoparticles. Engine parameters (brake thermal efficiency (BTE), brake-specific consumption (BSFC), exhaust gas temperature (EGT)) emission characteristics (CO, NOx, unburnt hydrocarbons (HCs), smoke opacity) measured. The B20M60 showed 2.38% reduction BSFC 3.38% increase BTE compared B20, significant reductions HC, CO, opacity. However, NOx increased by 6.57%. green synthesis method enhances sustainability, promising pathway cleaner more efficient operation UCO biodiesel, demonstrating effectiveness
