Full article:

This work analyzes the performance of the MWM 229.4 diesel engine in a 1-D computer simulation with biofuels B20 (20\% biodiesel and 80\% diesel, v/v) and D72B18E10 (18\% biodiesel, 10\% ethanol and 72\% diesel, v/v). The environmental impacts from fossil fuels has driven interest in renewable alternatives for sustainable energy to replace petroleum derivatives in thermal engines. A 4-stroke 3.92L diesel engine was modeled and validated in order to evaluate the engine’s torque, power, fuel consumption and thermal efficiency. The results showed that B20 and D72B18E10 had slightly lower performance compared to pure diesel due to their properties such as lower calorific value and cetane number. However, the presence of oxygen in the mixtures improved the quality and efficiency of combustion, resulting in greater thermal efficiency in some operational conditions.
