- Summary:
- One alternative to fossil fuels is the use of bioethanol in internal combustion engines. However, the application of this renewable fuel in compression-ignition engines is limited due to its low cetane number. This barrier, however, can be overcome by using additives that enhance this property. Consequently, additized ethanol emerges as a promising option with significant potential for decarbonization and improved combustion efficiency. In this context, the present study numerically investigated, using the CONVERGE CFD software, the use of additized ethanol in a compression-ignition internal combustion engine used in marine transportation. As a comparative baseline for each investigated setup, cases involving conventional diesel fuel were also analyzed numerically. The reaction mechanisms used for modeling the combustion of both additized ethanol and conventional diesel were validated against experimental data available in the literature. Di-tert-butyl peroxide (DTBP) was the studied cetane improver used in this study, blended with ethanol at weight fractions equal to 0%, 5% and 10%. In addition to the additive content in ethanol, the study also evaluated, through a sensitivity analysis, the impact of fuel injection strategies, including variations in injection timing (from 6 to 0 degrees before top dead center) and engine load levels (25%, 50%, 75%, and 100%). Key combustion, performance, and emission parameters were analyzed, including ignition delay, heat release rate, thermal and combustion efficiency, and emissions of CO₂, CO, NOX, CH4 and CO2eq. The results indicate that additized ethanol is a viable fuel for compression-ignition engines
