Análise da viabilidade financeira da aplicação de kit GNV em veículos leves

Abstract

Due to the increase in fuel prices and the global trend with concern for emissions of pollutants, this work has the objective of analyzing the economic and environmental viability of light vehicle flex engines for conversion of natural gas use. The study becomes possible since natural gas has the same physico-chemical characteristics pertaining to spark combustion engines. The methodology used to achieve the fuel cost reduction objectives was based on four criteria: Simple and Combined Payback, Net Present Value and Internal Rate of Return. Through the Minitab Software, future values for fuel prices were estimated to obtain return on investment. Two scenarios were created, the first with the substitution of gasoline for NGV, and the second with the substitution of ethanol also for NGV. Considering the criteria studied, it was observed that despite the increase in the cost of NGV in the last year, there is still a return on investment in the conversion kit within two years and also a reduction in fuel costs.
