Diseño y construcción de un banco de comprobación de inyectores mecánicos para el taller de maquinaria pesada

Abstract

The Heavy Machinery shop at Automotive Engineering Career of ESPOCH, does not have a mechanical injectors test bench, generating failures in the diagnosis and proper functioning of these injectors. In addition, the high cost of a test bench makes its acquisition difficult, therefore the objective of this Technical Project is the Design and Construction of a Mechanical Injectors Tester for the Heavy Machinery shop at Automotive Engineering Career of Escuela Superior Politécnica de Chimborazo. The methodology implemented had an inductive, deductive, and experimental approach, its construction is based on a simple design supported by mathematical calculations and analysis of the feasibility of acquiring the appropriate resources and materials. It will focus on data collection to reach conclusions or generalizations about the design and construction of the bench, so that it will be able to perform tests on the injectors such as drip tests, discharge time, injection form, opening pressure and calibration. By means of these methodologies it was possible to determine the validation of the mechanical injector test bench, thus assuring its capacity to measure accurately and reliably and evaluate the critical parameters of the injectors, which highlights its essential role in the diagnosis, maintenance, and repair of injectors in diesel engines. Finally, the development of a user and maintenance manual for the mechanical injector tester not only ensures optimal and safe operation, but also demonstrates professionalism and commitment to the quality of the tester.
