Reduction Of Fuel Consumption Of Fleets Of Small Trucks Used In Csn Mineração

CSN Mineração S.A. is the second largest exporter of iron ore in Brazil and is among the five most competitive in the market. Casa de Pedra currently has an approximate production capacity of 30 million tons per year. The fleets of small trucks 6x4 and 8x4 models are responsible for the ore movement, traveling an average distance of 10 km between origin and destination. 116 trucks of this size are used in CSN Mineração for the handling of products. Every month this fleet consumes an average of 550,000 liters of fuel. The objective of the work is to do a fuel consumption analysis by truck through the embedded telemetry system. The reports generated through this system provide the specific consumption of each equipment and also the specific consumption of each Driver. As reports are generated it is possible to assess which equipment had a higher specific consumption and, in this case, the respective trucks with greater consumption are directed to the Maintenance team for analysis and action in the event that a problem is identified in the equipment. At the same time, the analysis of the drivers who had the highest specific consumption and conducted a practical and theoretical training, addressing the techniques for a safer and therefore economical direction, is carried out. In 2019, the economy of fuel consumption type S10 was 204 thousand liters, which represents 9% of all consumption foreseen for the period.
