ANÁLISE DA INFLUÊNCIA DO DIENITRO NO CONSUMO DE COMBUSTÍVEL EM ÔNIBUS DIESEL DA GRANDE FLORIANÓPOLIS

Abstract

In urban society the transport of people and goods has always been associated with the generation of some form of pollution, whether atmospheric, noise or visual. Managing the urban environment is a major challenge: preserving environmental resources and also ensuring decent living conditions for the current population and for future generations. In the age of motorized and carbonized transportation, vehicles are the main source of air pollutant emissions, especially in large urban centers and important ozone precursors. An important advance in minimizing vehicle emissions and fuel consumption was the introduction of additives in the Brazilian market. This paper aims to analyze the influence of Dienitro on fuel consumption in diesel public buses in greater Florianópolis, as well as the pollution generated by vehicles. Measurements of kilometers per liter of diesel were taken, before and after the addition of Diesel with Dienitro, in part of the Emflotur (Florianópolis Public Transportation Company EIRELI) bus fleet that operates the collective transport from Biguaçu to the island of Florianópolis. Six buses were selected: 1 bus that uses Diesel S50 and EGR system, as well as 5 buses that use Diesel S10; where 2 of these vehicles use the EGR system and 3 the SCR system. As a result of the Dienitro additive of diesel bus engines, it generated a significant increase of kilometers driven per liter of diesel by up to 7.4% and, consequently, a reduction in greenhouse gas emissions.
