Reacondicionamiento e instrumentación del sistema de inyección GDI del banco motor Yes01 3111 enfocado a la simulación de fallos en cascada para el laboratorio de motores de la carrera de Ingeniería Automotriz de la sede Quito

Abstract

Vehicles in recent years have a large amount of electronic instrumentation that aims to control engine operation to achieve greater efficiency by minimizing fuel consumption and the amount of pollutant emissions produced by a MEP, because thanks to the implementation of sensors, actuators and electronic control units can know the status of the engine during operation actively adjusting various parameters to meet these objectives. The communication between sensors, actuators and electronic control units incorporated in the vehicles is possible thanks to the wiring harnesses, which are therefore of vital importance for the correct operation of the various vehicle systems, especially in the engine. The technological advances implemented in the vehicle have not only been electronic, but they go hand in hand with innovation in mechanical systems, an example of this is the GDI direct fuel injection system which makes use of mechanics to raise the fuel pressure by means of pump and electronics for the system pressure census and control of the injector operation, all focused on improving engine performance. Knowledge about GDI direct fuel injection systems becomes important since in Ecuador they underwent an exponential growth in the market since 2015, as several vehicle brands such as Hyundai, Kia, Mazda, Volkswagen, began to include this system in their vehicles, especially high-end vehicles. The implementation of the project allows to recreate failures in sensors and actuators of the G4KJ motor in the Yes01 3111 bench through the elaboration of a cascade failure generator, using analytical, deductive and descriptive methodologies that allow to interpret the manufacturer's connection diagrams and to generate new ones where the implemented elements are included, describing their expected operation.
