The latest European regulations require the use of biofuels by at least 10% as energy source in transport by 2020 to reduce the worldwide pollutant emissions. The combination between ethanol and gasoline provides a promising and in a same time a challenging approach. Ethanol has attractive properties based on the fact that this fuel can be produced from renewable energy sources without any modification on the engine. This biofuel was used as an alternative fuel due his higher evaporation heat, octane number and flammability temperature. In this study the pollutant emission (CO, CO2, HC, NOX) of a gasoline direct injection engine was investigated with an LPS 3000 chassis dynamometer together with the STARGAS 898 gas analyzer. Different studies for traffic operations were analyzed by using the LPS 3000 stand maintaining a constant traction.

Keywords: bioethanol, chassis dynamometer, emissions, gas analyzer
