Análisis y optimización del desempeño y emisiones de un vehículo con ecu programable bajo el ciclo de conducción de Riobamba

Abstract

The objective of the following investigation was to modify the parameters of the injection of fuel in the motor through the implementation of a programmable control unit. Its purpose was to avoid wasting fuel, taking into consideration that the automotive manufacturers do not perform their studies of the zone where the vehicle will function. This modification had as its base the data gathered on the functioning of the motor in routes previously established within Riobamba city. Within this route, data was collected employing a gas analyzer taking into account different states of the engine so this way it could determine which stages are efficient and which ones are not. The torque and power curves were obtained before and after the maps modification so that this way the obtained results could be analyzed. The controlled, selected unit was Megasquirt 2 Pro. The same adapted to the different sensors and actors of the injection system of the vehicle. The software TunerStudio MS was used for the modification of the different functioning parameters to achieve the objective of fuel optimization. As a result, it was obtained the decrease in fuel consumption from 0,265 to 0,1786 gallons in the course of the route, and decreasing 8% in engine power. The obtained data allowed generating a new map to decrease the consumption of the fuel and contaminating gas emissions. It is recommended that the vehicle possess an adequate communicating system so that this way has access to the electronic management of the motor in real-time to obtain information. It is recommended to verify previous studies of the mechanical and electronic systems that intervene in the management of the motor so that it is in optimal conditions contrary to fixing such defects.
