Desarrollo e implementación de manuales de usuario y guías de práctica para bancos de comprobación de bombas de inyección e inyectores electrónicos en la carrera de Ingeniería Automotriz Sede Quito

Abstract

This technical project seeks to determine the processes necessary to create instructions for use on CR1014, CRS300S, EPS208S test benches. The objective is to establish a base of manuals and practice guides for students of the Automotive Engineering course at the Quito campus, to promote the development of knowledge on CRDI injection systems. The methodology used presents a detailed technical analysis of CRDI test benches, followed by the drafting of manuals and guides based on the results of quick tests, which were performed in an estimated time of 10 to 15 minutes per bench, in order to assess the feasibility and functionality of the documents produced, in addition to collecting comments from teachers to have a better approach to the injection benches. The CR1014 bench is designed to test injectors and pumps operating at a high pressure condition of 1400-1600 bar, measuring injection flow, on the other hand the CR300S bench allows testing only injection pumps measuring flow at high precision minute per cycle, besides operating at conditions close to 1400 bar, on the other hand the EPS208S bench, is an equipment exactly for injectors measuring volume per cycle and working at a pressure of 1000-1500 bar, being efficient for electronic injection systems. Finally, with the information gathered, comparisons are developed with the three injection benches, for which outstanding results are obtained in the CR1014 bench, being the most complete at the moment of carrying out the different tests, since it can be used to evaluate pumps and injectors. Unlike the EPS208S and CRS300S benches, which are carried out individually. When presenting comparative values, injection time data of 2.5 milliseconds is obtained, giving a flow rate of 4.16 L/min and 0.4 ml per cycle respectively. The implementation of these manuals allows the training of students in a practical way, contributing with methodology to the career of Automotive Engineering and in turn, providing a better vision about the equipment that the university has in order to have a correct professional training.
