This study evaluates the performance and emission characteristics of Tamanu Methyl Ester (TME) biodiesel blended with Graphene Oxide (GO) nano additives at concentrations 25, 50, 75 ppm. Engine tests were conducted on a standard compression ignition engine under varying load conditions. Results indicate that TME20 blend 50 ppm GO (TME20+GO50) demonstrated optimal performance, achieving 4.8% improvement in brake thermal efficiency 12.6% reduction smoke opacity compared to diesel. The inclusion enhanced combustion through improved heat transfer catalytic activity, resulting reduced CO HC emissions. Notably, NOx emissions decreased by 10.19%, attributed GO's oxygen vacancies its role moderating peak temperatures. identifies TME20+GO50 as viable sustainable alternative conventional diesel, offering cleaner Future research should focus long-term operational effects further optimize their potential.

Abstract This study aims to operate a CRDI‐equipped single‐cylinder CI engine in dual fuel mode with pilot‐ignited WCB and port‐injected NH 3 fuel. The current experimentally investigates the influence of various AEFs on performance, combustion, pollutant emissions at peak load (4.14 bar BMEP @ 1500 rpm) conditions constant speed. obtained results showed that AEF was limited due its inherent combustion properties. Under aforementioned operating conditions, we achieved maximum 44.89% AEF. achieves BTE 29.33%. Moreover, operation, switches from diffusion phase operation rapid controlled as increases. ICT reduces 1488 1443 K when increases 0% 44.89%, respectively. Although injection notably decreased CO 2 , HC, CO, smoke by 57.14%, 60.26%, 71.42%, 67.59%, NOx increased 16.21% compared operation. BSEC dual‐fuel is 13.07 MJ/kW‐hr, which slightly higher than biodiesel mode, 12.17 MJ/kW‐hr. ICP, HRR, ID were 2.6 bar, 4.64 J/deg., 5 CAD, CD phasing reduced 9.3 CAD 7.98 However, turbulence within cylinder fluctuates significantly, COV IMEP reaching 5.23% an 44.89%.
