Análise operacional de caminhões a diesel e a viabilidade de implementação de caminhões a gás natural no transporte de combustíveis em Manaus – AM

Abstract

With an increasingly demanding market, especially when it comes to reducing costs—as in the case of road transportation—seeking alternatives that mitigate these costs is of fundamental importance. Accordingly, this course completion work aimed to understand the operation of diesel-powered trucks in the transportation of fuels in the city of Manaus and to assess the technical and economic feasibility of replacing them with trucks powered by compressed natural gas. The research in question, of an applied nature and quantitative approach, was based on a bibliographic review to understand the operational context involving these diesel trucks. Furthermore, real data were collected and analyzed from a local transportation company. Two equivalent models of Scania P-280 trucks were compared—one diesel and one CNG—considering fixed costs (such as depreciation, vehicle tax, insurance, and capital remuneration) and variable costs (such as fuel, tires, and maintenance). The results indicated that the CNG truck presented a lower variable cost, but a higher fixed cost, resulting in a total operating cost 2.23% higher than the diesel model. It is concluded that adopting this technology requires incentives and adequate infrastructure to be viable in the analyzed context.
