BIOCOMBUSTIBLES LÍQUIDOS EN COLOMBIA Y SU IMPACTO EN MOTORES DE COMBUSTIÓN INTERNA. UNA REVISIÓN

In the last centuries, the human being has been forced to use different sources in order to guarantee his energetic demand. it is for this reason that through the time technologies to exploiting fossil fuels have been developed, without taking into account the environment deterioration. furthermore, this indiscriminate exploitation has brought natural resources to their depletion. these factors have promoted the study of energies environmentally “friendly”. in this sense, biofuels seem to be a viable alternative to fossil fuels. this article is focused on the study of liquid biofuels in Colombia (bioethanol and biodiesel) by means of a detailed bibliographic revision. it is done to establish the state of the art of this technology. Moreover, the consequences of using them in internal combustion engines, particularly on those based on Otto and Diesel principles, are assessed.
