Diseño de un prototipo de emulador de bajo costo del sistema de inyección electrónica a gasolina LH-Jetronic utilizando una tarjeta de desarrollo programable

Abstract

This study addresses the design and development of a low-cost emulator prototype for the LH-Jetronic injection system, whose purpose is to provide an accessible alternative for educational institutions with limited resources, due to its low manufacturing cost compared to traditional simulation systems. An ESP32 controller module is implemented for the simulation of sensor and actuator signals, as well as a TFT screen, which facilitates the visualization of theoretical characteristics of the elements that make up the system. A web interface is also implemented in which students acquire theoretical knowledge by validating it with a brief questionnaire on each of the elements. After coding the signals, the validation of the similarity of the simulated signals by means of an oscilloscope is acceptable compared to the theoretical ones.
