Diseño y construcción de un módulo electrónico para predicción de consumo de combustible en un sistema de inyección electrónica a gasolina

Abstract

This technical work was carried out to predict the fuel consumption of a car to different tests. Under DIN 70030-2 standard and specific consumption on the road was necessary to build an electronic module, in response to the common problem of consumption in vehicles that have already run more than 100 thousand kilometers or older than six years. This module type does not exist in the national market, and importing it would be too expensive. That is why electronics were incorporated into the study process in the car. The use of programming software and the open-access resources for research allowed perform the data mapping lines and proceed to implement the electronic components they will interact with the Arduino board. Because it has a high potential for integration with different technologies such as sensors, GPS modules, and led screens to allow an experimental measurement of fuel consumption. The development of the design and the module construction allows the implementation of accessible technology materials, properly exposed to multiple tests in all electronic work and engineering projects investigation. These tests were carried out inside a Volkswagen Gol 1.6 2012-year vehicle with the proper connection of the electronic module. Three tests were carried out under natural and load conditions on the vehicle (rain, air conditioning, maintenance carried out days before the test, total weight, roads with peaks and valleys, traffic conditions, among others). This was developed inside and outside Riobamba city, obtaining a consumption within the normal operating conditions for both the CEPE and EPA standards, bearing in mind the error rates and percentages. It is recommended to analyze the obtained data with the international manufacturer's standards. Which are close to reality considering a correct installation of mobile elements and operation of the electronic module.
