Özet

This research investigates the application of Extended Coherent Flame Model-3 Zones (ECFM-3Z) to assess the performance and emissions of rapeseed oil methyl

ester (ROME). Experimental tests were carried out using a Lombardini 3 LD 350 model single-cylinder diesel engine, at 1600–3000 rpm with 200 rpm speed

increments, under full load conditions. For numerical analysis, STAR-CD/ESICE software was employed. Methyl Oleate (C19H36O2) was predicted as the surrogate biodiesel based on Gas Chromatography (GC) analysis and average mass calculation. Notably, the numerical analysis revealed a remarkable similarity in brake power

between the experimental and computational investigations. In the range of 2400–3000 rpm, the biodiesel's performance exhibited a maximum deviation of 5%, primarily

attributed to pumping, thermal, and friction losses. In terms of emissions, carbondioxide (CO2) emissions were consistent with the findings of the experimental study,

with a maximum disparity of 10%. However, carbon monoxide (CO) emissions ranged from 57% to 65% lower than those observed in the experimental study, while nitrogen

oxide (NOx) emissions exhibited a reduction of 63% to 84%. In contrast, oxygen (O2) emissions were notably higher, ranging from 93% to 117% compared to the

experimental study, and exhaust temperatures were elevated by 33% to 49% in comparison to the experimental results.
