Implementation of a Programmable Electronic Management System for Internal Combustion Engines

Several injection and ignition systems have been developed and tested since the invention of the internal combustion engine. As environmental regulations have become more stringent over the years, an electronic injection and ignition systems of the mixture air/fuel was implemented in the vehicles. Since then these systems have constantly been improved with the inclusion of devices, sensors and actuators that help them work more efficiently, both to gain power and for the enforcement of environmental laws in force in each country. For the correct operation of the engine electronic management it is extremely important to develop a software that can perfectly control the inputs (sensors) and outputs (actuators) information. The task of adjustment and calibration of the software requires a programmable module, which is connected to the vehicle and tested with various settings until an ideal fit between performance and emissions can be reached. This paper proposes the implementation of a programmable electronic management system that can replace the original system of the vehicle without exceeding the limits of pollutant emissions described in the Brazilian legislation. To achieve this goal, it will be necessary to analyze the behavior of the vehicle with its original management system and with the use of specific equipment such as the gas analyzer (emission pollutants), the automotive scanner (parameters of the management system) and the dynamometer (power and torque). Therefore this work presents the methodology, testing, advantages, disadvantages and limitations of implementing a programmable electronic management system for an internal combustion engine.
