| Resumo: | Efforts in research and development of new technologies to reduce emission levels of
pollutant gases in the atmosphere has intensified in the last decades. In this context, it can be
highlighted the modern systems of electronic engine management, new automotive catalysts
and the use of renewable fuels which contributes to reduce the environmental impact. The
purpose of this study was a comparative analysis of gas emissions from a automotive vehicle,
operating with different fuels: natural gas, AEHC or gasoline. To execute the experimental
tests, a flex vehicle was installed on a chassis dynamometer equipped with a gas analyzer and
other complementary accessories according to the standard guidelines of emission and
security procedures. Tests were performed according to NBR 6601 and NBR 7024, which
define the urban and road driving cycle, respectively. Besides the analysis of exhaust gases in
the discharge tube, before and after the catalyst, using the suction probe of the gas analyzer to
simulate the vehicle in urban and road traffic, were performed tests of fuel characterization.
Final results were conclusive in indicating leaded gasoline as the fuel which most contributed
with pollutant emissions in atmosphere and the usual gasoline being the fuel which less
contributed with pollutant emissions in atmosphere |
