However, the country is not ready to adopt this technology on a large scale. In this way, this document proposes the development of the Quality Function Deployment (QFD) methodology in order to define and categorize Engineering Characteristics (EC) of an electric hybridization kit for motorcycles in the Colombian context. The proposed kit is oriented to the Street\sport segment, with an engine displacement between 111 c.c and 135 c.c. Besides, a technical and competitive analysis of the kit, with direct competitors in the Colombian context, based on the requirements provided by a multidisciplinary group of engineers and potential users is presented. Finally, the results obtained from the methodology implementation are classified according to the PDS categories proposed by Pugh for a further stage of product design. © 2018 Institution of Engineering and Technology.

Departamento de Ingeniería de Diseño; Ingeniería de Diseño (GRID)Design and implementation processes of a functional model of an electric hybridization kit for modification of a manual transmission motorcycle are presented in this paper. Considering the complexity of the development and the need to integrate different disciplines of engineering and design, the design process follows the VDI Guideline 2206 and proposes the use of the V-model. Requirements stated by a multidisciplinary group of engineers and potential users are presented as the starting point of the design methodology, followed by a conceptual design phase, and a detail design process according to three specific domains: mechanical engineering, electronic engineering and information technology. In order to achieve fuel economy and fewer emissions, a control with three different driving modes [Internal Combustion Engine (ICE) mode, Hybrid Mode and Regenerative Mode] is proposed including an intelligent switch between a 125 c.c ICE system and a 1000 W BLDC electric motor. Finally, a functional model of the modification kit is assembled on the motorcycle and its functionality is verified. The results show a considerable decrease in the use of the ICE, identifying the electric modification kit as a viable solution for the environmental problem generated by the motorcycles segment. © 2020, Springer-Verlag France SAS, part of Springer Nature.Ítem Estudio de pre-factibilidad para la conformación de una comercializadora de refrigerantes orgánicos para vehículos de motor de combustión interna localizada en la ciudad de Medellín(Universidad EAFIT, 2013) Chavarriaga Duque, Sebastián; Londoño Márquez, Nathaly; Álvarez Hernández, Juan EstebanSe hizo un estudio de pre-factibilidad para identificar y analizar los elementos claves para establecer una empresa comercializadora de lubricantes refrigerantes en la ciudad de Medellín -- Los refrigerantes se clasifican de acuerdo a su composición química y de esto depende su rendimiento y calidad -- Los refrigerantes son esenciales para la vida útil del vehículo y actualmente no existe una oferta de productos con altas especificaciones para nuestro mercado -- Los refrigerantes orgánicos contienen unas características especiales de funcionamiento, calidad, rendimiento y composición que los hacen diferenciadores en el sector -- Esto ofrece una oportunidad de negocio para satisfacer un mercado poco explorado en la ciudad de Medellín -- El mercado objetivo para el cual se ofrecerá el producto mencionado, se estima en 6 mil vehículos que pertenecen al 7% del total circulan en la ciudad de Medellín: tipo automóvil, campero y camioneta; además tienen una antigüedad no mayor a 10 años y pertenecen a los estratos 4, 5 y 6 -- El montaje de esta empresa requiere una inversión inicial de $86 millones de pesos para compra de equipos de oficina, mercancía e insumos, trámites legales y adecuaciones a un local y bodega comercial -- De los cuales el 50% será aportado por socios y el restante se financiará a través del Fondo Nacional Del Ahorro a un término de 5 años -- Según el estudio organizacional, inicialmente la empresa estará conformada por un administrador de ventas, un administrador operativo y un auxiliar de bodega y se conformará como una Sociedad por Acciones Simplificadas -- A través de la evaluación económica y financiera del presente trabajo de calculó que invirtiendo 86 millones, es una empresa que puede pagar dicha inversión y generar un valor adicional por 272 millones en un término de 5 años de la evaluación -- Ésta misma evaluación se hace sin el cálculo de los valores a la perpetuidad de los ingresos -- Es decir genera una Tasa interna de retorno superior al 74%E.A, superando el Costo del Capital Ponderado del proyecto, el cual es de 7,2% -- A partir del análisis de los diferentes factores de mercado, técnicos, legales y económico financieros evaluados, identificamos que éste proyecto empresarial es viableÍtem Estudio de prefactibilidad para la creación de un Centro de Servicios Técnico-Mecánicos, para vehículos automotores terrestres que operan con motores tipo Diesel(Universidad EAFIT, 2009) Piedrahita Llano, Juan Camilo; Fernández Durango, Jorge Andrés; Castaño Jaramillo, Cesar AugustoÍtem Estudio prospectivo tecnológico de combustibles alternativos para automóviles(Universidad EAFIT, 2009) Gärtner Escobar, Felipe; Londoño Velásquez, Santiago; Mora Gutiérrez, Luis AlbertoÍtem Evaluation of two strategies NMPC into HIL applied to the operation of an internal combustion engine(Springer-Verlag France, 2018-02-01) Chica, J.A.V.; Torres, A.G.D.; Chica, J.A.V.; Torres, A.G.D.; Universidad EAFIT. Departamento de Ingeniería de Producción; Ingeniería, Energía, Exergía y Sostenibilidad (IEXS)The hardware in the loop (HIL) platforms constitute an accelerated engineering design medium that subsequently reduces the risk of failure in the implementation process. This fact is enhanced when the designer is faced with extremely complex tasks and when design errors can lead to destructive and costly testing. The design of complex algorithms such as non-linear controllers applied to electronic control units of combustion engines, is a task of higher complexity level, and tests with incorrectly adjusted drivers can result in engine breakdown. This document reports the performance and effectiveness of a two-HIL scheme as an interactive design platform used for the design of electronic control units ECU, for internal combustion engines. The implementation and adjustment of two NMPC strategies aimed at optimizing the operation of the engine from three fronts: energetic, economic and environmental, involving independent and simultaneous objectives, give an account of the usefulness of the interactive design scheme. © 2017, Springer-Verlag France.Ítem Implementación de un sistema de simulación de carga y un sobrealimentador eléctrico en un motor de combustión interna para estudiar su desempeño(Universidad EAFIT, 2011) Solarte Henao, Stevens Mauricio; Hermández Lordui, Mónica PatriciaÍtem NMPC controller applied to the operation of an internal combustion engine: formulation and solution of the optimization problem in real time(Springer-Verlag France, 2018-02-01) Chica, J.A.V.; Torres, A.G.D.; Acosta Maya, Diego Andres; Chica, J.A.V.; Torres, A.G.D.; Acosta Maya, Diego Andres; Universidad EAFIT.

Departamento de Ingeniería de Procesos; Procesos Ambientales (GIPAB)This work develops a systematic methodology able to identify the desired work points, the metamodels were evaluated varying air–fuel ratio, ignition timing, compression ratio, and combustion duration using design of computer experiments and RSM. It provide the possibility to determine optimal control parameters, according to selected objectives and operating constraints. This methodology is able to automatically identify the optimal engine calibration with less computational effort. Only in this way, the reliability of an integrated metamodel/optimizer approach can be included in a general-purpose that is to identify the engine calibration that minimizes motor vehicle emissions according to European emission standards (European Union in Off J Eur Union 50, 2007). As long as it improves mean effective pressure and reduces exergy destruction due to heat transfer and combustion process. Since, in internal combustion engines, more than 30–40 % of fuel energy wastes through the exhaust and just 12–25 % of the fuel energy converts to useful work. So, researchers are motivated to recover the heat from the waste sources in engines using the ways which not only reduce the demand of fossil fuels, but also reduce the harmful greenhouse gases and help to energy saving (Hatami et al. in Neural Comput Appl 25(7–8):2079–2090, 2014). The advantages of this contribution include the ability to study a wide range of parametric space and to independently evaluate physical and chemical processes, and detailed in-cylinder information, which is normally not available or is inaccessible in experiments. The uncertainty of the information in this unexplored design region can be quantified. Finally, the problem of optimizing involves three optimization fronts, energetic, economic and ecological (Chica and Torres in Int J Interact Des Manuf 12(1):355–392, 2018). © 2019, Springer-Verlag France SAS, part of Springer Nature.
