Eeduction of CO and CO<inf>2</inf> emissions to the environment with B5 and B10 mixes of biodiesel based on algae (chlorella)

Abstract:

This article presents an experimental study to evaluate the emissions of polluting gases in an engine using diesel of fossil origin and mixtures with biodiesel based on algae at 5 and 10%, denominated B5 and B10, respectively. The results show that CO emissions reduce up to 8.1% with the use of B5 and 11% with B10 throughout the range of revolutions tested, with the exception of 1500 rpm. In the case of CO2, an increase in emissions is generated with a maximum of 5% using biofuel, except in idling with B5 and at 3000 rpm using B10. NOx emissions have a high idle increase of 37% using B5 and 21.4% using B10, while in the rest of revolutions they do not exceed 4.1%.
