The depletion of non-renewable energy, emissions of harmful gases to the atmosphere and the impact of fuel consumption in road transport of cargo in Brazil, are motivating the study proposed by this work.
In order to reduce fuel consumption, field tests were conducted, where tests were performed for three main segments of heavy transport in the state of Rio Grande Sul We used different combinations of engine power and ratio gear.
The test vehicles were operated on a test route that has similarity to the main trade routes of the state that is Porto Alegre - São Paulo, where consumption showed differences between the settings, always indicating the best specification, validating the methodology applied.
