Diseño y construcción de un banco de pruebas para la comprobación de electrobombas de gasolina en motores de combustión con inyección indirecta

Abstract

This document describes the process of building a test bench to test gasoline electric pumps in order to verify and give guarantees of this through tests such as voltage, amperage and fuel flow in liters per minute, these tests will allow us to know the state in which is the electric pump to be subsequently installed in the vehicle with total security. The design of the bench is done using computer aided design tools (CAD) in this case, Autodesk Inventor ensuring that the final design is detailed and accurate for the work to be done. In addition to helping us reduce the time required for the preparation of drawings and possible improvements in the design before its final construction. Stainless steel was used for the construction of the bench to avoid corrosion and maintain durability, especially since the equipment is operated with gasoline. If the electric pump, due to different circumstances, is operating at higher or higher values than those specified, the amperage and voltage increase, causing the electric pump to heat up and subsequently burn out. Most gasoline electric pumps handle a range of 30-40 psi which will be easy to check on the test bench. The original electric pump proved to be the most efficient and reliable, maintaining a constant high flow rate with moderate increases in amperage and voltage and indicated lower consumption in all tests. Its performance indicates a high quality of construction and components, reflecting a positive and consistent relationship between voltage, amperage and flow.
