    Diseño y construcción de un banco de pruebas de motores monocilindricos de cuatro tiempos a gasolina

    A test bench was designed and built to study the operating variables (power, torque, speed, fuel consumption) of a four-stroke single-cylinder Gasoline internal combustion engine according to the theory of mechanical design; in which tests were carried out modifying the operating speed of the engine, making measurements of fuel consumption, torque and power. Solidworks software was used for the design of the bench and its respective static analysis. The engine used is an AKT 110 cc semi-automatic with four gears. As a result of the tests, the curves that relate fuel consumption, power, torque with engine speeds in each of the gears were obtained.

    Evaluación energética de la cogeneración mediante un motor de combustión interna acoplado a un sistema de refrigeración por absorción usando biogás como combustible
    (2021) Avilez Olea, Juan Rafael; Peréz Dickson, José Camilo; Rhenals Julio, Jesús David
    Cogeneration systems are now increasingly appearing in the industrial and commercial sector, since their implementation brings with it a number of energy, economic and environmental benefits. This makes a study of the general operation of the cogeneration system implemented with a biogas-fueled ICM and coupled to an absorption refrigeration system, which is a very useful application of this type of system. The objective of this work was to perform an energy analysis of the entire cogeneration system. The development of this strategy begins with the definition of the operating parameters in the engine, and then the modeling of the system using the ASPEN HYSYS® computational tool. Subsequently, a parametric analysis of the output variables in the system is presented. The results show that if an adequate selection of the methane composition in the fuel is made and the optimal operating parameters are adjusted in the ICM, good results can be obtained, being possible to implement them in real industrial applications.
