The aim of this work was to evaluate the emission of nitrous oxide (N₂O) using a diesel engine at laboratory scale without a catalytic converter with diesel/biodiesel blends (%) of 95:5 (B5), 90:10 (B10), 85:15 (B15), 80:20 (B20), 75:25 (B25), and 50:50 (B50). Measurements of N₂O in the exhaust gas were made using an experimental setup based on photoacoustic spectroscopy using a quantum cascade laser that was validated to be selective and sensitive in the range from 1.7 to 2.72 ppmv. According to the experimental results, the lowest N₂O concentration was found to be in the B5 diesel/biodiesel blend. Also, formaldehyde and methane compounds were detected qualitatively, indicating the possible presence of these chemicals in the combustion of diesel/biodiesel blends.
