Rediseño e implementación de un banco de pruebas de bombas inyectoras diesel para el laboratorio de motores de la Escuela de Ingeniería Automotriz.

Abstract

The redesign and implementation of a test of diesel injection pumps, aims to provide an equipmentof learning that enables to developskills and acquireknowledgeincalibration of diesel injection pumps.The research initiatedwith the collection of information, background and operation of diesel injection system, characteristics and functioning of universal testing benches depending on the current state of the art,components and electronic devices of last generation in control systems.The process started by the redesign of the mechanical structure and modificationof components for linear pump according to safety regulations andby mean of the result of finite element analysis. The hydraulic redesign consists of elements selected under ISO standards and operating tables, thecontrol system of the bench was designed and manufacturedprior to the selection of elements by optimizing resources and adopting currenttechnology elements.It was obtained as functional test benchthat enables thecalibration ofthediesel pump as accurately as possible that incorporatesa wireless, Bluetoothcommunication system and asystem ofautomatic conditioning of temperature for the fluid.Having concluded theresearch,operation and maintenance manuals for the test bench, practical guidesfor accurate operation, were developed, making possible the student achieves abetter understanding. It is recommended to follow the manual operation of the testing bench as well as its maintenance for a better life-timeof the testing bench systems when making practical activities.
