Diseño y construcción de un banco de pruebas semiautomático para la determinación de fallas de inyectores en autos a gasolina

Abstract

The degree project work “Design and construction of a prototype test bench for determining injector failures in gasoline cars” is prepared by applying the knowledge acquired during training in professional life with the purpose of designing, developing and program equipment capable of verifying the status of gasoline vehicle injectors in an economical way, with a solid structure. This degree project aims to demonstrate the ability and creativity when designing machinery used in daily life, without the need to depend on external agents since we are creators of the test bench in order to see the state of the gasoline injectors, it began with an analysis of alternatives to take design variables for an efficient test bench, followed by a mechanical study to determine the type of material to use, SolidWorks software was used for the mechanical design and make the plans. of each component for its mechanical assembly, together with an electrical design that provides the correct location of the sensors, and actuators present in our bench, together with the free Arduino language programming in order to carry out tests in different work cycles, in small, medium and high with this it is possible to simulate the behavior of a vehicle, at the same time it provides the level of the liquid provided by the injectors through ultrasonic sensors and the information is presented on an LCD screen, demonstrating the status of each of them. Injectors in real time Finally, functional tests were carried out to determine the work cycles are the same in the injectors at the same time, together with the sensors which gives me the correct information on the gasoline level, present errors that affect the measurement of the liquid were corrected. That may affect the determination of injector failures, the test bench is in operation to make constant improvements in order to correct and innovate in the automotive field.
