Different solutions have been proposed to reduce air pollutants and greenhouse gases to combat the severity of environmental pollution. Research on alternative fuels in the transportation sector can utilize existing infrastructure while minimizing pollution. This study aims to assess engine performance and emission changes by varying the blend ratios of OME2, an E-fuel-based fuel. Experiments were conducted by adding OME2 to a spark ignition(SI) engine, followed by a numerical analysis using GT-Suite. Results showed that increasing the OME2 energy ratio led to a decrease in engine output(up to 9.27 % reduction in IMEP). However, it also improved thermal efficiency(up to 3.67 % increase) due to enhanced combustion. Moreover, the addition of OME2 resulted in a maximum reduction of 35.67 % in NOx emissions. Thus, utilizing OME2 as an alternative fuel can be an effective and environmentally beneficial approach. |
