Um estudo sobre sistemas de injeção eletrônica e mecânica de combustível dos motores a diesel nos navios da Marinha do Brasil

Abstract

An engine is a machine that transforms a type of energy in mechanical energy, for that, it’s necessary to have a injection system for the fuel, that is in the tank, reach the cylinder. The mechanical and electronic injection systems, on diesel engines, are composed with different parts, have nonidentical impacts over the environment, have distinct costs, quality of workmanship and spare parts. For this reason, this study was developed to discuss those caracteristcs and investigate which one of the systems has the best use on Brazilian Navy ships. To be accomplhised, the research was based on manuals, articles and a interview to collect relevant data to the theme. The result after this study found that the Brazilian Navy has to keep improving workmanship qualification, upgrade machinery on it’s bases, manuals and publications referents to maintenance and establish partnerships with companies and manufactures of maritime engines.
