Levantamento de emissões atmosféricas por veículos automotores leves

Abstract

Atmospheric emissions, derived from anthropogenic activities, mainly with the presence of compounds chemically harmful to nature, constitute a major problem of current air pollution. And nowadays, with the use of combustion engines, automobiles as our means of transportation, which facilitated the displacement becoming indispensable nowadays for the comfort, time and space. In such a way the present work had as objective to survey the contribution of combustion gases produced by atmospheric emissions by light motor vehicles within the collective of company X by calculating the contributions of atmospheric emissions due to their routine trajectory a vehicle spreadsheet sent by Company X's transportation sector with various models and brands was used. The contributions of emissions of Non-Methane Hydrocarbons (NMHC), Carbon Monoxide (CO), Carbon Dioxide (CO2) and Nitrogen Oxides (NOX) to the vehicles were calculated. Emissions were also simulated for the commuting routine within Company x in Londrina and a trip to Company X in the city of Ponta Grossa and which vehicles have the greatest contribution to the emission of pollutants were identified. Generally speaking, through the emission calculations, the brands that have the largest contribution individually, in the NMHC emission is the Ford Focus with approximately 15.6%, for CO it is the Renault Fluence with 17.5%, for the NOX and CO2 is the Volkswagen Kombi with 24.1% and 16.4% respectively.
