Abstract
Biofuels play an important role in meeting the world demand for liquid fuels, mainly for environmental reasons, largely due to their lower level of pollution with their burning and processing. This paper aims to perform a theoretical analysis of a compression-ignition internal combustion engine using the bio-oil produced from a microwave-assisted pyrolysis process. The combustion process of the bio-oil is modeled in the Chemical Equilibrium for Applications (CEA NASA) software. Physical characterization and gas chromatography coupled with mass spectrometer of the bio-oil are performed, which shows a chemical composition of carbon (39.1%), hydrogen (4.8%), oxygen (20.2%), and an LHV of 7781.98 kJ/kg. From these results, the energy and exergy modeling in a diesel engine is performed, varying the λ-factor from 0.8 to 1.2 for two situations: one using the bio oil/diesel blends in the ratio of 25%-75% and pure diesel oil. The results show the feasibility of energy and exergy performance for the bio-oil used.
