Utilización de software automotriz para la reducción de emisiones contaminantes de un vehículo a inyección electrónica mediante la modificación de la memoria flash sin afectar su torque y potencia en la ciudad de Riobamba

Abstract

This experimental work aimed to modify the cartographic maps of the original programming of an ECU belonging to an electronic injection vehicle; through the use of automotive software called RACE EVO and NEW TRASDATA. Focusing on the variation of the lambda factor and different work parameters. In addition, using an exhaust gas analyzer and automotive dynamometer, to make comparisons of results. In practice, exhaust gas emission data, torque values, and maximum power reached the same as those carried out in the equipment mentioned above. The different tests served to form an initial database managed as maps references for reprogramming. Subsequently, the ECU was read through the DIMSPORT team, the same as that allowed the extraction of original maps. RACE EVO software carried out modifications of certain parameters where four maps of performance, each with major performance changes. The first three are obtained with the variation of the value of the lambda factor, where maps were generated with 0.86, 1, and 1.06 respectively, on the fourth map. In addition to the lambda factor, parameters such as injection pulse, ignition advance variation, etc. After gathering data, we proceeded with the information filtering and processing using MiniTab statistical software. It concluded that, by modifying the cartographic programming maps of the engine computer, where the value of the lambda factor was altered and work parameters reducing considerably the emissions of polluting gases with stable values of torque and power. It is recommended to consider various types of software and hardware to reprogram the ECU data, to perform a deep analysis for such studies.
