Investigation of the combustion and emissions of lignin‐derived aromatic oxygenates in a marine diesel engine

As a hard-to-decarbonize sector, the shipping industry is experiencing demands to accelerate transition from fossil fuels alternative low-carbon fuels, significantly reduce negative impacts on environment. Biofuels are regarded as one of solutions for decarbonization in marine sector. This paper introduces lignin-derived drop-in biofuel, 2-methoxy-4-propylphenol (2M4PP), non-edible feedstocks and investigates engine performance using its 10% (by volume) blend with standard diesel fuel (DF) at variable speeds loads. Results show insignificant difference between in-cylinder pressures proposed DF. The diesel-2M4PP emits less carbon monoxide (CO) nitric oxide (NOx) than DF all by up 39.6% 10.7% respectively, although brake-specific consumption (BSFC) higher. A Ricardo wave model, which validated experimental data 2400 rpm speed full load, investigated adjusting injection pressure, timing, duration nozzle diameter. optimal parameters, i.e., 214 bar 6° 41.4° duration, 0.37 mm injector orifice, lead best improved brake power, reduced NOx emissions, limited influence BSFC hydrocarbon emissions compared © 2021 Authors.
