This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Resumen: En la actualidad la facultad de Ingeniería Mecánica de la Universidad Tecnológica de Pereira cuenta con equipos para la medición del desempeño efectivo de motores de combustión interna de baja cilindrada, pero no para motores de alta cilindrada. Para dar solución a esta problemática se diseña y construye un banco de pruebas que cumple con las exigencias requeridas para medir las curvas de desempeño de un motor Hércules G1600. El equipo de análisis consta de un freno electromagnético o retardador modelo CFK-65, el cual genera diferentes cargas de frenado que están en dirección contraria al giro del cigüeñal del motor. Para dar transmisión desde el motor se instala un acople flexible tipo junta universal marca FT-CAR, junto con dos acoples fabricados para unir el cardán a cada uno de los componentes. La estructura del banco de pruebas esta diseñada de tal forma que se puede sostener cualquier tipo de motor, esto se debe a que tiene tres grados de libertad que se adaptan al tamaño de motor. Buscando satisfacer las necesidades primordiales para generar la fase investigativa por parte de los alumnos, el banco medirá la velocidad angular originado en el cigüeñal del motor y el par con respecto al tiempo para crear la cuerva de desempeño del motor. Para medir la velocidad angular se instalará un encoder de 96 pulsos por minuto, éste estará acoplado mediante una polea a la volante del motor. Para medir el par se instalará una celda de carga de 200 kg posicionada simétricamente al eje de giro del dinamómetro, de tal forma que ésta a partir de su deformación censa una fuerza, la cual acompañada de una relación matemática permite determinar el par. El freno electromagnético a partir de un flujo de campo magnético que se genera en las bobinas, logra atravesar los sectores del disco de inercia al interior del dinamómetro, lo cual genera fuerzas electromotrices inducidas en dirección contraria al movimiento, generando el efecto de frenado requerido...

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Resumen:La potencia, la velocidad y el par de torsión, entre otras propiedades de desempeño del motor, resultan en la actualidad objeto de estudio de gran importancia. Es sumamente útil la realización de bancos de pruebas para la obtención de datos reales. En este documento, se muestran los resultados del diseño y construcción de un banco de pruebas para un motor de combustión interna desarrollado en la Universidad Tecnológica de Pereira con fines de investigación y docencia. Se describen en él, las partes y las características más importantes del banco y los componentes que se diseñaron y construyeron para el mismo. A tal fin, el motor se hace girar a distintas revoluciones y a diferentes cargas, para luego obtener las curvas de potencia y par versus rpm, simulando así las cargas que se generan en un motor estando funcionando dinámicamente pero analizándolas siendo estático. La realización de este trabajo de grado se basa en la adecuación de un sistema de freno de disco convencional adaptado a la volante de un motor Hércules Engine de 2,7 L; se describe también el montaje de diferentes partes, como la mordaza, pedal de freno, bomba mecánica para el sistema de frenado hidráulico; adecuación de los relojes de velocidad y de presión, para el posterior estudio de las condiciones de trabajo bajo diferentes regímenes de carga así como para la observación de las gráficas arrojadas.

Book excerpt: Introducción: :En este informe se recogen los trabajos de recuperación, actualización y puesta en funcionamiento del banco de pruebas (freno Prony) construido por estudiantes de la Facultad de Ingeniería Mecánica de la Universidad Tecnológica de Pereira en el año 1976 [1] con propósitos didácticos, para motores de hasta 15 kW, buscando aumentar la capacidad didáctica del laboratorio de motores de combustión interna. El banco de pruebas base fue dotado con sistemas que permiten medir las variables necesarias en el estudio de los motores: consumo de aire, consumo de combustible, revoluciones del cigüeñal y par. Estos elementos permiten calcular la potencia al freno, la eficiencia mecánica, la relación aire combustible, el consumo específico de combustible y el de aire...

Download or read book Climate Change Policy written by Michael Bothe and published by Eleven International Publishing. This book was released on 2005 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the research results of an interdisciplinary study on climate change policies by the Enforcing Environmental Policy (EEP) Network, a project supported by the Human Dimension Potential Programme. Contributions are from highly qualified economic and legal specialists based at research institutes across Europe. The book gives answers to several questions related to the implementation of the international rules on climate change, most notably the Kyoto Protocol. It analyses ways and means to facilitate and encourage compliance with the objectives of the Kyoto Protocol. It is addressed to policy-makers, academics, business-sector and stakeholders throughout and outside Europe. Due to its interdisciplinary approach, this work is a distinctive and unique product compared to the existing literature on the subject. The effective implementation of climate protection and clean air policy requires an understanding of the political, legal and economic structures and constraints facing policy makers - and this is exactly what this book offers.

Download or read book The Future of Development written by Gustavo Esteva and published by Policy Press. This book was released on 2013-10-09 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: On January 20, 1949 US President Harry S. Truman officially opened the era of development. On that day, over one half of the people of the world were defined as "underdeveloped" and they have stayed that way ever since. This book explains the origins of development and underdevelopment and shows how poorly we understand these two terms. It offers a new vision for development, demystifying the statistics that international organizations use to measure development and introducing the alternative concept of buen vivir: the state of living well. The authors argue that it is possible for everyone on the planet to live well, but only if we learn to live as communities rather than as individuals and to nurture our respective commons. Scholars and students of global development studies are well-aware that development is a difficult concept. This thought-provoking book offers them advice for the future of development studies and hope for the future of humankind.

Available in PDF, EPUB and Kindle. Book excerpt: Our Unsustainable Life: Why We Can't Have Everything We Want With the concept of the Imperial Mode of Living, Brand and Wissen highlight the fact that capitalism implies uneven development as well as a constant and accelerating universalisation of a Western mode of production and living. The logic of liberal markets since the 19thCentury, and especially since World War II, has been inscribed into everyday practices that are usually unconsciously reproduced. The authors show that they are a main driver of the ecological crisis and economic and political instability. The Imperial Mode of Living implies that people's everyday practices, including individual and societal orientations, as well as identities, rely heavily on the unlimited appropriation of resources; a disproportionate claim on global and local ecosystems and sinks; and cheap labour from elsewhere. This availability of commodities is largely organised through the world market, backed by military force and/or the asymmetric relations of forces as they have been inscribed in international institutions. Moreover, the Imperial Mode of Living implies asymmetrical social relations along class, gender and race within the respective countries. Here too, it is driven by the capitalist accumulation imperative, growth-oriented state policies and status consumption. The concrete production conditions of commodities are rendered invisible in the places where the commodities are consumed. The imperialist world order is normalized through the mode of production and living.
