Effect of 2,5-dimethylfuran-diesel blends on the performance and emissions characteristics diesel engines

This paper investigates the effects of blending 2,5-dimethylfuran (DMF) with diesel fuel on the performance and emissions of a heavy-duty Hyundai D6AC diesel engine. The fuels studied include pure diesel and DMF–diesel blends with volumetric ratios of 10%, 20%, 30%, denoted as DMF10, DMF20, DMF30, respectively. Simulated using AVL BOOST software. The results indicate that increasing DMF content leads to reductions in engine power by 2.37%, 4.75%, 7.16%, and torque by 2.39%, 4.77%, 7.18%. Conversely, brake specific fuel consumption increases by 2.22%, 4.71%, 7.38%. In terms of emissions, CO decreases by 9.05%, 15.82%, 19.90%, and soot by 3.6%, 11.49%, 20.72%, while NOx emissions increase significantly by 46.39%, 92.88%, 140.25%, corresponding to the DMF blending levels.
