Análise do consumo de combustível de um automóvel de passeio em trajeto com faixas elevadas para travessia de pedestres e trajeto livre

Abstract

In this work is presented basic concepts of internal combustion engines (ICE), factor which influence fuel consumption, and a study about the impact of the elevated pedestrian crossings over a passenger car’s fuel consumption. Tax incentive governmental programs such as the Inovar-Auto and the Rota 2030 aim to optimize the Brazilian energy matrix and reduce environmental impacts, measured via technical standards. However, the real-world fuel consumption and emissions may drastically vary upon external factors such as climate conditions, traffic, driver behavior and road conditions. The study found that the automobile spent 52 s (14,7%) and consumed 21,2% more, to travel along a 5400 m route containing 4 elevated pedestrian crossings, compared to a route free of crossings. Alone, each crossing added, on average, 13 s (63,7%) to the course. Furthermore, each crossing caused an increase of 96,2% in fuel consumption, equivalent to R$ 0,064, compared to a free course of the same distance. Due to the significative impact, the installation of speed reduction dispositive must be carefully studied.
