Análisis del mapeado de ecu programable que optimice el desempeño y emisiones de un automóvil liviano bajo el ciclo de conducción de Riobamba

Abstract

The objective of this research was to develop programming of a programmable control unit to optimize the performance and emissions of a light vehicle based on the modification of the parameters of the injection and advance maps. The selected control unit was Megasquirt 2 Pro, whose interface was programmed using the TunerStudio MS software, modifying the map parameters. Road tests were carried out within the city of Riobamba, and on a dynamometer, the data obtained through a gas analyzer was collected, taking into account the different states of the engine. The torque and power curves were obtained before and after the implementation of the unit of control to analyze the results obtained and optimize fuel consumption. As a result, a decrease in fuel consumption from 0.3952 to 0.3617 gallons was obtained. In the case of the hp power, the factory one has 5% more hp than the programmable computer. Programming of a programmable control unit was developed to optimize the performance and emissions of a light vehicle based on the modification of the parameters of the injection and advance maps. It is advisable to take into account that all the electronic and mechanical systems of the vehicle are in perfect condition, as well as the measuring equipment, before carrying out any test drive.
