description Currently, the Laboratory of Experiments of the Antonio Nariño University (Puerto Colombia Headquarters) has an internal combustion engine which is not operational and in need of maintenance, as well as its start-up for academic, scientific and research activities. This directly impacts the results of academic experiments carried out by students who. This generates a failure for the future engineer of the Antonio Nariño University, since a Laboratory is closely related to the reproduction of engineering experience that the future graduate will face in the industry. In this sense, knowing the operation and characteristics of an internal combustion engine becomes a relevant factor in the student's training. In addition, its use constitutes a recovery of a fixed asset of the institution. In this order of ideas, this degree project proposes to recover and start this engine, evaluating the associated thermodynamic processes, implementing a gravimetric system for the measurement of specific fuel consumption, among other activities.

En este sentido, conocer el funcionamiento y características de un motor de combustión interna, se torna un factor relevante en la formación del estudiante. Además, su utilización se constituye en una recuperación de un activo fijo de la institución. En este orden de ideas, este trabajo de grado propone recuperar y poner en marcha este motor, evaluando los procesos termodinámicos asociados, implementando un sistema gravimétrico para la medición del consumo especifico de combustible, entre otras actividades.Ingeniero(a) Mecánico(a)PregradoPresencialProyectospaUniversidad Antonio NariñoIngeniería MecánicaFacultad de Ingeniería Mecánica, Electrónica y BiomédicaPuerto Colombia BarranquillaMotores de combustión internaInternal combustion enginesDesarrollo experimental del análisis termodinámico de los procesos y parámetros asociados al motor de combustión del laboratorio de experimentos de la UAN Sede Puerto ColombiaTrabajo de grado (Pregrado y/o Especialización)http://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85EspecializadaORIGINAL2021_RobinsonLopezyJesusPeralta2021_RobinsonLopezyJesusPeraltaTIGapplication/pdf1720748https://repositorio.uan.edu.co/bitstreams/c80d1042-ab26-4765-8d90-4851fe42261f/downloadf878fa37a642c213413c04ceefef2fc6MD512021_JesusPeralta_Acta2021_JesusPeralta_ActaActa Jesusapplication/pdf161981https://repositorio.uan.edu.co/bitstreams/05352adf-e29c-4222-addb-5feb4a286663/download3311b3963606718caf85f6955f04ffd0MD522021_RobinsonLopez_Acta2021_RobinsonLopez_ActaActa Robinsonapplication/pdf160603https://repositorio.uan.edu.co/bitstreams/b02804e2-7eb7-4509-8fbb-d3b236ce97b9/download29704c77812f29dac392b6252d62a3b0MD532021_JesusPeralta_Autorizacion2021_JesusPeralta_AutorizacionFormato autorización de autoresapplication/pdf1089801https://repositorio.uan.edu.co/bitstreams/a28ba4ff-d82a-455b-944a-1d3629dbabdb/downloadf829c618fb0bcb93511406b05f8aab0eMD572021_RobinsonLopez_Autorizacion2021_RobinsonLopez_AutorizacionFormato autorización de autoresapplication/pdf892194https://repositorio.uan.edu.co/bitstreams/4a3b5941-bba0-4e5f-843d-bb8c01b90949/download70f7b1295b6ca28974db5013600ba9f4MD58CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml; charset=utf-8811https://repositorio.uan.edu.co/bitstreams/9c89ee35-6790-4a0d-8f2c-27f709e80a2f/download9868ccc48a14c8d591352b6eaf7f6239MD59TEXT2021_RobinsonLopezyJesusPeralta.txt2021_RobinsonLopezyJesusPeralta.txtExtracted texttext/plain97152https://repositorio.uan.edu.co/bitstreams/50a10622-c6cb-48d1-84fc-bb265f3d12db/download25cc486bac03ab774211e79de60d26baMD5102021_JesusPeralta_Acta.txt2021_JesusPeralta_Acta.txtExtracted texttext/plain1700https://repositorio.uan.edu.co/bitstreams/fc6870ff-fa56-4d24-963e-566c2978d2e0/downloadfa8c717adc5f96748f3792cd982dd47eMD5122021_RobinsonLopez_Acta.txt2021_RobinsonLopez_Acta.txtExtracted texttext/plain1700https://repositorio.uan.edu.co/bitstreams/b6c173ce-6da1-4c72-bbec-4020e3a86aac/download2d6a5a39553a95a28a31049d8739a52aMD5142021_JesusPeralta_Autorizacion.txt2021_JesusPeralta_Autorizacion.txtExtracted texttext/plain6https://repositorio.uan.edu.co/bitstreams/824153aa-253e-4a25-bb4e-444a2c32d707/download6d93d3216dc4a7f5df47d4876fbec4d3MD5162021_RobinsonLopez_Autorizacion.txt2021_RobinsonLopez_Autorizacion.txtExtracted texttext/plain6605https://repositorio.uan.edu.co/bitstreams/72e78602-ba1d-4f86-bba1-ae43ddf33540/download5a49f787ab4bc54873837b345d6c2081MD518THUMBNAIL2021_RobinsonLopezyJesusPeralta.jpg2021_RobinsonLopezyJesusPeralta.jpgGenerated Thumbnailimage/jpeg10657https://repositorio.uan.edu.co/bitstreams/b508548d-e686-48e7-9f79-a4048b8a3d11/download06689ab13b005aec3ffc9365b3eadf9fMD5112021_JesusPeralta_Acta.jpg2021_JesusPeralta_Acta.jpgGenerated Thumbnailimage/jpeg15656https://repositorio.uan.edu.co/bitstreams/eecdc7a4-8948-424b-a823-ea29a78cb56c/download02e8c4c84b8f5a51e0cfb70a163c065bMD5132021_RobinsonLopez_Acta.jpg2021_RobinsonLopez_Acta.jpgGenerated Thumbnailimage/jpeg15691https://repositorio.uan.edu.co/bitstreams/e2f63445-f2bf-47da-8fa8-1755c694d63f/download9beae5091c2371251256414d4d724efdMD5152021_JesusPeralta_Autorizacion.jpg2021_JesusPeralta_Autorizacion.jpgGenerated Thumbnailimage/jpeg13727https://repositorio.uan.edu.co/bitstreams/0c594edd-c3ca-4a10-8575-3c97f16d38aa/downloada97c8faaf78780a1d8abff1a4120eb38MD5172021_RobinsonLopez_Autorizacion.jpg2021_RobinsonLopez_Autorizacion.jpgGenerated Thumbnailimage/jpeg15952https://repositorio.uan.edu.co/bitstreams/f5475d97-f85b-4fda-b527-8f451cdc2be3/download5de55a92f9a8b8432bb9b08a611f877eMD519123456789/6033oai:repositorio.uan.edu.co:123456789/60332024-10-09 23:07:15.918https://creativecommons.org/licenses/by-nc-nd/4.0/Acceso abiertorestrictedhttps://repositorio.uan.edu.coRepositorio Institucional UANalertas.repositorio@uan.edu.co
