Electric Fuel Injection Engine Reliability Problems in Developing Countries, Cape Verde Case Study

Abstract

Due to the need to reduce greenhouse gas emission rate, nowadays vehicles are manufactured in different types of fuel injection, one example is the engines with electronic injection and management. This vehicles present several advantages for the environment and it reduces the amount of fuel used in the vehicle, becoming more economic, what is also important due to the prediction for decrease of the available quantity of fossil fuel. The mechanical injection vehicles are no longer manufactured what make the electronic fuel injection engines to begin to be introduced in Cape Verde. The biggest problem in Cape Verde, when it comes to maintenance of vehicles, is the fact that the majority of mechanics working in vehicles maintenance, learned with the practice, very few of them had the opportunity to study. These new vehicles require staff with a certain level of knowledge. Mechanics and workers generally have an elementary school education; or have never finished high school. Many of them began working as apprentices and were trained on the job by more experienced staff. As a result, most of their skills were acquired on the job in practical "hands-on" contexts without any theoretical training. This paper aim to study the state of the art related to maintenance problems and strategies in electronic fuel injection engines, as well as the study of problems faced in Cape Verde with the maintenances. This paper will propose a solution for a reliable maintenance, for these devices in countries with lack of technical support focusing in the study of case in Prai city, Cape Verde.
