Resumen
In recent decades the population growth in Curitiba and metropolitan region resulted in an increase in the fleet of vehicles in public transportation system, leading to high fuel consumption and consequently emissions. To monitor these emissions in Curitiba, the agency responsible for public transport, carries only the opacity test, which measures the amount of smoke emitted by the bus, so this work bothered to analyze the main gases expelled by the exhaust (O2, CO2, CO , NO, NO2 and SO2) of some fleet vehicles owned by the Redentor LTDA, which has a total of 360 buses. We compared emissions between the different models, different injection systems, vehicle age and type of fuel used. Tests have shown that emission of CO2 and CO concentration was lower in the electronic injection vehicles in relation to mechanical injection, while the parameters of NO and NO2 was not conclusive for this. The biofuel-powered vehicle had lower emissions of gases analyzed in relation to similar features of a diesel-powered.
