2-Methylfuran (2-MF) has emerged as a promising renewable alternative fuel, primarily due to its sustainable production processes and potential significantly reduce soot emissions. However, when blended with diesel, it presents challenges, including an increase in NOx emissions, which is attributed the lower cetane number (CN) of M30 blend. This study investigates effect adding 2-ethylhexyl nitrate (2-EHN), enhancer, blend (30% 2-MF by volume), on combustion characteristics exhaust Experiments were conducted using modified four-cylinder, four-stroke, direct-injection compression ignition (DICI) engine featuring common rail fuel injection system. The was evaluated under different load conditions, brake mean effective pressure (BMEP) ranging from 0.13 1.13 MPa, while maintaining constant speed 1800 rpm. incorporation 1.5% 2.5% 2-EHN into enhanced performance, indicated reduction maximum rise rate, shorter delay (ID), extended duration (CD). Furthermore, brake-specific consumption (BSFC) reduced 2.78% 5.7%, thermal efficiency (BTE) increased 3.54% 7.1%, respectively. Moreover, inclusion led significant Nox 9.20–17.57%, most observed at 2-EHN, where hydrocarbon (HC) decreased 7.93–21.59%, carbon monoxide (CO) 12.11–33.98% compared without 2-EHN. Although slight emissions higher concentrations levels remained than those pure diesel. results indicate that addition can effectively mitigate trade-off between low oxygenated fuels.
