SUMMARY:

Two fuels with different compositions are produced from sugarcane: farnesane and a variety of biodiesel. Emission limits were adapted from specific emissions (g/kWh) to emissions index per kilogram of fuel consumed (Emissions Index [g/Fuelkg]) and emissions index per kilogram of CO₂ emitted (Emission Combustion Index [g/CO₂kg]). The purpose of this change is to achieve more precise results for NO_x, CO, and THC emissions from these two biofuels. It was proven that NO_x emissions for biodiesel were reduced in most operating modes compared to mineral diesel, while farnesane showed small reductions. For CO emissions, farnesane obtained values very similar to mineral diesel, while biodiesel presented a considerable increase. As for THC emissions, a reduction was observed for biodiesel, especially at high loads; however, these emissions for farnesane were higher than the reference diesel. For the three types of contaminants studied, it is remarkable the differences between the indices and the standardized limit for NO_x emissions. Nevertheless, adapting specific emissions for emissions indices proved advantageous for biofuels
