Implementação e análise de um sistema de gerenciamento eletrônico aplicado a motores de ciclo Otto

Abstract

With the use of electronic injection, it was possible to develop techniques that helped drivers achieve lower fuel consumption and emissions, as well as improved drivability. Among these, we can highlight the cut-off, which cuts off fuel injection when the control unit interprets favorable conditions for it to do so. An example of this is when the vehicle is traveling at speeds above 50 km/h with gear engaged, such as on a long downhill slope, and does not require the engine to work to maintain that speed. The engine does not “turn off” because the transmission is connected to the engine, causing the weight of the vehicle on the plane to maintain its work. The general objective of the work consists of studying the implementation and analysis of an electronic management system seeking new perspectives related to the efficiency of the combustion engine, showing the gains in terms of economy and efficiency. The specific objectives include: understanding how an internal combustion engine works with an Otto cycle; discuss the electronic injection engine management system and finally demonstrate the efficiency of the GX-35 engine used for this experiment. Verifying and attesting the results obtained through this improvement. The results achieved showed that the electronic injection management system studied in this work is capable of managing an Otto cycle engine and going beyond, allowing better technical characteristics according to the needs of the research
